The manuals and the accompanying practical assignment, that are to be designed, have certain requirements. It has to introduce vibration measurements and BK Connect to the students in such a way that a basic understanding, for future use, of BK Connect is gained. The assignment had to be clear enough that students, when following instructions, receive results comparable to those included in the teacher’s manual. The measurements in the assignments also have to be reproduceable. The practical assignment starts off with a series of questions mostly to get familiar with the program and its capabilities. The students will be introduced to concepts such as importing data, making a frequency spectrum, making a frequency spectrum vs time and changing properties such as the frequency span of these spectra.   The second part is about measuring the vibrations produced by a drill in both a balanced and imbalanced state. This measurement will be done with an accelerometer made by BK. The spectra of these vibration signals can afterwards be analyzed with the use of BK Connect. The two results can

CHARACTERIZATION OF A LASER CHIP DIODE IN TODAY’S WORLD OF INCREASING TELECOMMUNICATION, THE INTERNET IS INDISPENSABLE; ALMOST EVERYONE USES IT. A FAST AND RELIABLE WAY FOR DATA TRANSPORT IS IMPORTANT.

The company VTEC develops and produces lasers that are used to control a light signal in an optical fiber. The assignment for the project is to develop a measurement method that can quickly and reliably determine important laser characteristics. For example, the setup must be able to determine a voltagecurve, a luminous intensity curve, and the optical spectrum as a function of the given electrical current. In the current state of the project, it is possible to create a working setup with which these characteristics can be determined accurately. Also, theoretical research about lasers and measurement methods is conducted for future project groups to continue this project.

FROM VACUUM FLASK TO CALORIMETER IN ORDER TO REPLACE AN OLD CALORIMETER, RESEARCH HAS BEEN DONE INTO A (CHEAPER) REPLACEMENT. THIS PROJECT FOCUSES ON A VACUUM FLASK FROM IKEA, WHICH WAS THOUGHT TO BE A SUITABLE REPLACEMENT.

In the course Engineering Physics there are multiple experiments performed by students in varying scientific disciplines, of which some are reliant on thermal-fluid sciences. In the first and third year there are experiments performed using a calorimeter. These experiments require a certain accuracy, which cannot be achieved with the current calorimeter. This calorimeter is not accurate enough to reach the required five percent maximum error which is demanded of the obtained result in the E&E experiments. A vacuum flask, or insulated container, is bought as a replacement for the old calorimeter. Measurements performed by a research contributor at Fontys University of Applied Sciences Eindhoven indicate that the vacuum flask can be considered as a replacement of the calorimeter. From the results of these measurements, the vacuum is expected to be able to measure the specific heat within an accuracy of two percent. The goal of this project is to develop an experimental setup using the vacuum flask as a calorimeter, to measure the specific heat with an accuracy of two percent or less. Measurements with the vacuum flask have been performed. The cooling curves of the old calorimeter and the vacuum flask containing different volumes of water have been made. From the results the vacuum flask turned out to be more efficient than the old calorimeter and indicated that between a volume of 1 to 1.7 L of water the flask is the most efficient. In order to determine the specific heat, two methods for

10

measuring have been used. In the first method, fluid is present in the flask with a certain temperature and another fluid is added to the flask with a different temperature. By measuring the temperature, the specific heat can be determined. In this method, water has been added to water and ethanol has been added to ethanol. In the second method, a material with a certain temperature is added to a fluid with a different temperature. Either the material or the fluid is present in the flask beforehand, in order to get the flask on the same temperature as the material or fluid present in the flask. By measuring the temperature, the specific heat can be determined. In this method, a block of copper has been added to water and the other way around and a block of copper has been added to oil. Result: Our clients will have a more efficient and cheaper ‘calorimeters’ for first- and third-year experiments.

STRESS RELATED REPETITIVE MOVEMENTS STRESS COULD BE MEASURED IF IT IS POSSIBLE TO DISTINCT UNCONSCIOUS REPETITIVE MOVEMENTS FROM NORMAL MOVEMENTS. THE USE OF MACHINE LEARNING AND USING A MORE STATISTICAL METHOD FOR DETERMINING THESE MOVEMENTS ARE COMPARED TOGETHER.

Now that everyone in this world is getting busier, stress related complaints are increasingly more common. For some people with certain forms of autism it is not self-evident to contact a doctor or therapist when experiencing these complaints. For this group in particular it is important to measure stress without disturbing the patient. Certain forms of autism combined with stress would sometimes result in unconscious repetitive movements. These movements however, could also be found at people without autism. Besides that stress could be measured in vital body functions, it is also possible to measure the discomfort of stress with help of these stress related repetitive movements (SRRM). The starting point of this project were two preliminary researches in which Machine Learning was used to determine two specific types of stress related repetitive movements. With preliminary researches mainly focussing on measuring SRRM that are linked to autism, it is also interesting to measure these movements at people without autism. The daily dose of SRRM could be used as a indicator of stress. This will be measured with use of the accelerometers in a mobile phone, carried in a pocket to minimise the inconvenience of the measurement.

FONTYS UNIVERSITY OF APPLIED SCIENCES

To measure SRRM at people with or without autism, various forms of SRRM are tried to be distinguished from repetitive movements that are not stress related. This determination is done in two ways. One way, the determination is done using machine learning. This method proved to work well on the previous researches. Another way, the determination is done deterministic using various statistical methods. This is done for simplifying the resulting application. The results of the two determination methods will eventually be compared together. After collecting data of SRRM and non-SRRM with help of a self-made MATLAB program and many test subjects, the two methods showed different results. After optimizing the machine learning based determination program in MATLAB, an accuracy of 95.2% for determining the right movement is achieved. After manually analysing the data for creating a deterministic program in MATLAB an accuracy of 70.1% is achieved. In both programs, a safety is build in so that a doubtful movement is more likely to be categorised as SRRM than non-SRRM. However, due to lack of time, the assumption that the data follows a normal distribution is made to the deterministic program. This assumption probably lowers the accuracy of the deterministic program. Further research

is required to determine the actual distribution type of the data. This project has shown that various SRRM could be distinguished from some non-SRRM. This statement is valid for some autism related SRRM as well as some non-autism related SRRM. The determination is proven to be possible with use of a mobile phone, carried in a pocket. Out of the two tested analysis methods, using machine learning turns out to provide the highest accuracy of 95.2%. Determination with use of the more simplistic and statistics based deterministic model only provides an accuracy of 70.1%. This could be increased by doing further research. The research has resulted in two working methods for stress related repetitive movement determination. The Machine Learning algorithm shows the most promising result. Even though it is fully functional, the program is not ready for commercial use. The program needs to be formed into an application for mobile phones to make it useful for caregivers.

NAI KRISTAL REALISATION OF A READOUT SYSTEM FOR A GAMMA RADIATION UNIT THIS PROJECTGROUP IS MAKING AN READOUT UNIT FOR A NAI-CRYSTAL. THIS UNIT IS USED TO DETECT RADIOACTIVE MATERIAL. UMC Maastricht is a hospital that researches in several medical fields, one of which is in the field of radiation. UMC Maastricht has several radiation detection units, also known as scintillator detectors. The purpose of the project is to build a readout system for one of the scintillator detectors (Na-I crystal). The readout system should be able to measure an incident photon and process the total amount of photons in to an energy spectrum. Photons have different energy levels where: E_photon~f_photon. An isotope sends out photons with expected energies. By detecting photons and translate these into electrons by using a photomultiplier tube, the readout system determines the energy spectrum of the isotope.

12

The composed readout system consist of the Na-I crystal which is supplied by a high voltage, UCS-30 (800V). The readout unit is chosen to be digital. This is why an oscilloscope is used as an ADC (8-bits). The oscilloscope sends a signal to a labVIEW program, which converts individual peaks to their amplitude. The number of amplitudes is then plotted against the energy level, this gives the energy spectrum. In this project the energy spectrum of two different isotopes is determined, namely: Co-60 and Cs-137. The energy spectrum is depended on the voltage given by the high voltage. This is why the high voltage is first calibrated before measuring any energy spectrums. Two different calibration are carried out for the UCS-30. First the offset of the UCS-30 is determined. This turns out to be +6.28 V over a range of 100 to 900 V. Secondly the UCS-30 must be stable over time, otherwise the spectrum will rescale over de x-axis. The maximum error found when doing a time-depended measurement is 0.17 % at 900 V.

V results in a rescale to a larger energy spectrum (shifts to the right). Lastly the spectrum of both Co-60 and Cs-137 are determined with an high voltage of 800 V. For Cs-137 a peak is expected at 662 keV. The measurement of Cs-137 show a peak at 660 keV. The same is done for Co-60. Here the expected peaks are found at 1173.2 and 1332.5 keV. The measurement of Co-60 show the two peaks to be around 1175 and 1135 keV.

It is only expected that the x-axis will rescale when changing the high voltage. To check the change of the energy spectrum when introducing a change in the high voltage, the high voltage will be put on 700, 800 and 900 V. The measurements show the following: when lowering the high voltage to 700 V, the x-axis rescales to a smaller energy spectrum (shifts to the left). 900

Result. Our client is researching faster and has better ways to detect radioactive material. The setup that we have made is a digital one. It is more user friendly than working with an analog setup. It is also adjustable because the analog components are ‘programmed’ in labview. For using the labview program, only a ADC is necessary for converting the analog signal to a digital one.

RUTHLESS INNOVATING PLANET A SHOWPIECE FOR GLOW 2019

Every year Fontys is asked to organise and create a showpiece to show at the annual light festival GLOW in Eindhoven. This year the group of students that works on this showpiece is interdisciplinary. Students come from the Mechatronics, Engineering and Engineering Physics departments of Fontys University of Applied Science in Eindhoven. The project is guided by Ellen Moerman, teacher and Fontys employee, and Tom Weerts, GLOW production manager. The project is supported partly by KAW Architects Eindhoven. After a period of brainstorming and idea-elimination, one idea has been chosen to become the GLOW showpiece. The showpiece is called Ruthless Innovating Planet. This showpiece will be built to tell a story about energy misuse and the effect of the overconsumption of fossil fuels. Its message is a strong one, fitting in this time where people regularly make statements about the environment. From the Middle Ages, through the Industrial Revolution, to the Age of Technology, people’s goal has been to use the planet’s resources to benefit human welfare. For a long period of time this has not caused major changes in global climate and industrialisation, innovation and welfare went hand in hand. At this point in time however the effects of people’s actions are slowly becoming apparent and society have become more aware of the desperate state of the planet earth. This knowledge has become a fact known to many and is a problem addressed by most of the world’s governments. However, no one is able to provide a solution to this massive problem. The goal of the showpiece is to make GLOW visitors think about how the world revolves mainly about wealth and a growing economy. One of the main motors of the economy is the fossil fuel-industry. Even though much attention has already been given about reducing the consumption of fossil fuels in the past, they are still responsible for powering the majority of worldwide industry. This is also because large amounts of energy is misused in terms of efficiency. Therefore

FONTYS UNIVERSITY OF APPLIED SCIENCES

the message that the showpiece communicates, has to leave a big impact on the GLOW visitors. To accomplish this, the showpiece itself is larger than life. In the first place a large sphere with a 3,2 m diameter is hung above a lake of fake fire which is created with a fire effect using a fog machine and orange coloured lamps. Below the fire, four truck-engines are placed, which seem to fuel the lake of fire. In summary: a sphere is suspended over a lake of fire, produced by the (misused) energy of the four engines. The sphere is constructed as a lattice work that resembles the equatorial and meridian lines of earth as they appear on globes. Therefore the sphere represents earth. It is in fact a somewhat abstract depiction of earth. The message is clear: The planet will soon burn up due to society’s current view on innovation and energy (mis)use.

MONDOMED FOAM THE PROJECT IS A RESEARCH PROJECT IN ORDER OF MONDOMED. MONDOMED IS A MEDICAL SUPPLY COMPANY SPECIALISED IN PVA FOAM. MONDOMED IS ALREADY PRODUCING A PVA FOAM USED FOR MEDICAL GAUZES. MONDOMED wants to make the gauze applicable for abdominal surgery. This means the gauze has to be X-ray detectable. The gauzes currently used are made of cotton and are woven with a barium sulphate doped wire. The barium sulphate is a good X-ray contrast which makes the wire clearly visable on a X-ray. The problem of using the same technique is the implementation of this type of wire in the PVA foam. The focus of this project is thus to make the foam X-ray detectable. We have split the group in to two sub-groups. The first group focusses on possible ways of implementing the barium sulphate wire. This in contrast to the second group which focusses on other ways of making the foam X-ray detectable.

CREATING AN ULTRASOUND DOPPLER PHANTOM OF THE CAROTID ARTERY An ultrasound phantom that mimics the flow of blood through the common carotid artery has been created. Using ultrasound Doppler velocimetry, the speed and pulse of this flow has been measured and compared to a real arterial flow. A teacher at the MBRT (Medische Beeldvormende en Radiotherapeutische Technieken, Dutch for Medical Imaging and Radiotherapeutic Techniques) study at Fontys Eindhoven asked us to create a phantom with which ultrasound Doppler measurements of the blood flow in the carotid artery can be performed. An ultrasound phantom is a device which simulates a part of the body, in this case the carotid artery, so that it resembles the real body part when viewed with an ultrasound scanner. This phantom can then be used by students to practice ultrasound imaging. Ultrasound imaging is a medical technique in which soundwaves of ultrasonic frequencies are transmitted into the body, and the reflected waves are used

SYMPOSIUM ENGINEERING & TECHNOLOGY IN PRACTICE


HEALTHCARE & TECHNOLOGY

to create a 2D image of the body. Conditions and diseases can then be spotted and diagnosed based on the ultrasound images. A Doppler ultrasound measurement uses the Doppler effect to measure the velocity of the blood flowing in the patients veins. By transmitting soundwaves at ultrasonic frequencies into the artery, and measuring the frequencies of the waves that reflect from the blood, the velocity of the blood can be determined. This can be used to diagnose certain arterial diseases, such as stenosis, a narrowing of the artery. The phantom must meet a number of requirements: 1. The materials used to mimic the tissue and blood should allow for a Doppler ultrasound measurement to be performed on the phantom. 2. The phantom must mimic a carotid artery suffering from stenosis. 3. The phantom must be able to pump a blood mimicking fluid through a simulated carotid artery with the rhythm and speed of a beating heart. 4. The phantom must be a closed system that continuously reuses its fluid. 5. The phantom must be non-perishable and reusable. 6. The phantom must be cheaper than existing Doppler ultrasound phantoms. In order to make this phantom materials have been researched that could be used to mimic the blood and surrounding tissue. For the tissue-mimicking material three different substances were tested: gelatine, ultrasound gel pads and silicon. For the blood-mimicking fluid, a combination of water, glycerol and table salt was used based on literature. A hole was created in each of the phantoms that would represent the carotid artery, and a pump system was designed that could pump the blood-mimicking fluid through this phantom artery at the same rhythm of the heart. When tested, the gelatine phantom resembled human tissue accurately on an ultrasound image. However, the gelatine grew mould in roughly 2.5 weeks after creation, and so it could not be used to

FONTYS UNIVERSITY OF APPLIED SCIENCES

create the phantom. While the ultrasound gel pads were somewhat useable as a tissue-mimicking material, the air bubbles within this material caused interference in the ultrasound image. When the silicon was first made, it too had these air bubbles. After using a vacuum chamber to remove these bubbles however, the silicon phantom provided a clear image of the vein, including the stenosis, and the blood flowing through it. It did not however, resemble human tissue visually when seen through an ultrasound scanner. The silicon has also proven to be non-perishable. Two silicon phantoms were made; one with a stenosis and one without. The pump system was created out of a 200 ml syringe and a stepper motor. The syringe was modified to have one inlet and one outlet, with valves controlling the flow. On the plunger of the syringe a rack gear has been bolted. By connecting this rack to a gear attached to the motor, the plunger can be pushed up and down by changing the rotational direction of the motor. The used motor can, according to its specifications, provide a torque of 0.8 Nm. When tested on its own, the pump system proved capable of pumping at a rate similar to that of a human heart. When connecting the pump system to the phantom, the pump proved capable of pumping the blood-mimicking fluid through the phantom at a velocity of around 0.8 m/s at a rhythm of roughly 100 BPM, which is comparable to the blood flow in real carotid artery. The system is fully closed, with no fluid needing to be added or removed while the system is pumping. The system is also considerably cheaper than existing phantoms. However, the turbulence of the flow in the phantom limits the accuracy of the measurements, and this is a problem that remains to be solved. A previous ultrasound Doppler phantom prototype had been created, but this device was large, perishable, and required fluid to be manually poured into the pump during its functioning. Solutions to these problems had to be found. Unlike the previous phantom prototype, the materials used in this device are

completely inorganic with no expiration date, while still providing a clear image of the blood flow. The device is also considerably smaller and lighter than the previous prototype, and the closed system means that no liquid has to be inserted or removed from the phantom. The phantom only needs to be plugged in for it to work, with no further effort required of the user. With the phantom, students at MBRT can be tought how to use the Doppler velocimetry function of their ultrasound scanners without requiring a human subject. The artery of the phantom, which resembles a common carotid artery in diameter, must be located using the scanner. When the student succeeds at this, they can measure the velocity and rhythm of the blood flow using Doppler velocimetry and compare this to a real heartbeat. Two phantoms have been made; one with a narrowing in the artery, which mimics a stenosis, and one with a healthy artery. By not telling students which phantom has a stenosis, it would allow them to learn how to search and diagnose such a condition. The pump can also be programmed to provide various rhythms and velocities of the blood flow, which can teach students to diagnose conditions like arrhytmia (an irregular heartbeat) or hypertension (high blood pressure). Currently the students mostly practice ultrasound on themselves or on other students, and since these students are generally healthy, they do not have the opportunity to practice diagnosing illnesses. By using this phantom, students will be better prepared to help real patients. FONTYS TUTOR Ir.

SHOE TIME THE THEORETICAL BACKGROUND FOR THE ASSIGNMENTS IS THE SAME AS WHAT THE STUDENTS NEED TO COMPLETE IT. THIS CONSISTS MOSTLY OF BASIC VIBRATIONS AND FOURIER ANALYSIS. FOURIER ANALYSIS CAN BE USED TO LOCATE FAULT IN MECHANICAL EQUIPMENT BY MONITORING THE GENERATED VIBRATIONS. 

It is important that the final product meets the user requirements to satisfy the client. The final project deliverables should be: - A prototype of the final product, a shoe with sensors to measure the shear forces and the bending of the foot. This shoe still has to be comfortable to walk. - A report of the designing process. - Measurements and creations of the project. These are the end results of the project that the user wants. To make sure these results will be reached there need to be a view S.M.A.R.T (Specific, Measurable, Acceptable, Realistic, Time) goals defined. GOAL 1: The main goal is to make a prototype shoe which can measure the shear forces of a foot. In the sole of the foot, 6 sensors should be placed. Each of the sensors the middle electrode should stay in a fixed position while the other electrode is free to move. The sensors should be connected to the multiplexer system. So, instead of having one device per input signal, the multiplexer system should combine the input signals and create a one single output line.

16

GOAL 2: The next goal is to make a report where all the specifications of the product and the choices that have been made are described. The report should be readable by the client, the producing company and the tutor of the project. This report is meant to be a roadmap, everybody with an engineering background should be able to produce the same shoe with the same results. GOAL 3: The third goal is to have the drawings of the product so precise that they can be used to produce the unit by another company. This could be measured by letting someone look at the drawings who doesn’t know about the project and let that person decide if the drawings are clear. The drawings need to be finished by the end of the two quarters and be added to the report. Goal number 1 is a very large goal and basically the assignment of this project. This goal can be split into different smaller goals. That can be reached during the project. GOAL 1.A The material selection of each part of the shoes should meet the system requirements of that part. This can be measured by using the requirements list as a checklist. The material selection of all the parts should be done before the end of the first quarter.

MINOR ENGINEERING

GOAL 1.B The research about the shoe design should be finished by week 4. Looking for a design that can be comfortable for the final user so, in this way, the measurements analyzed can be as trustful as possible. If the feeling of the shoe is not comfortable it will make the user walk in a bad way that is translated in bad measurements. The decision of 6 sensors, is looking for the pressure distribution under the foot. Having the main points of pressure in four different areas. Being the fingers area the one with more pressure and more bending. Looking for better measurement in this area, three sensors symmetrically positioned in this area can provide reliable measurements. Some sensors are more focused on normal force, so this time we want to get sensors that can measure shear force for shoes.

FONTYS UNIVERSITY OF APPLIED SCIENCES

Fontys Paramedische Hogeschool gives us the assignment to redesign a shoe prototype that measures the flexing of the foot. This prototype is going to be used by people that have a disease, affecting the way they walk. One of these diseases is diabetes, a disease that has risen from 108 million in 1980 to 422 million patients in 2014 according to data of the World Health Organization.

The assignment is to redesign the shoe, so it could be reliable with the use of new sole material and therefore reduce the error in the measurements. At the same time, a decrease in the dimension of the sensor is needed for a better fit in the sole, adding the possibility of positioning the sensors near the borders of the sole that is the place where the most bending occurs during the walking.

The last prototype generates the sensor that will provide the measurements of the bending, the issues that it had was the reliability of the materials used and the dimensions of the sensor. The issue with the material is based on the same bending that the sole has, making that the silicone started to rip in the zones where the sensor was placed. This prototype was not reliable and not trustful in the measurements and caused as a result, a difference of voltage to what it supposed to be.

The Smart wrist positioning functions by the principle of using two cylindrical wedges, which rotate around their center axis, to regulate the inclination of the upper surface. For the control and programming of the system, it uses a real time control of the servo motors which are connected to a PC based motion controller, the Delta AX864E. Robot Operating System (ROS) is used for the high-level control which has to control all the motion path of the robot. While CODESYS, which is a program to develop control systems is in charge of all the lowlevel controls, whose tasks are to regulate the motors and keep them rotating until a target position is reached. The applications could be any situation where precise positioning or fast movement is needed. - Patient table at hospitals - Milling machine bed - Balancing tables - End actuator for a robot arm. The Fontys Team consist of 3 teams of different disciplines with a tutor and a teacher expert per team. Delta Electronics is working together with Fontys, by sending 2 experts to work alongside the team and by funding the project.

PORSCHE 986 CAN-AM EEN PORSCHE BOXSTER IS EIGENLIJK EEN ONDERGESCHOVEN KINDJE IN DIE FAMILIE. MAAR WAT ALS JE DIE NU VAN EEN ANDERE CARROSSERIE VOORZIET? In samenwerking met het designbureau VanBerlo in Eindhoven en carrosserie firma Van Thull Development uit Oss zijn we de samenwerking aangegaan om een Porsche Shooting Break te ontwerpen, oftewel de cabriolet omtoveren tot een kruising van een coupe en een station met drie deuren. Het heeft heel veel ontwerp en zoektijd gekost, maar naar alle waarschijnlijkheid kunnen we mallen trekken van het prototype aan het einde van de minor. Op de foto’s verschillende stadia van het werk in progress. De auto gaat vanaf nu door het leven als 986 Can-Am Aangezien dit de fraaiste Shooting Break is, is het eigenlijk dus 1. de laatste om te bouwen, alles hierna is immers zinloos. Na de Porsche 917’s hadden bepaalde races, ik kom er zo op, ook geen zin meer en zijn die gestopt. 2. Op de Amerikaanse markt is hij onthuld, Detroit zelfs, en is daar héél goed verkocht! 3. De dichte versie heet Cayman, daar is het een verbastering van. 4. Waar de naam naar refereert is ook een middenmotor auto, sterker, de motorontwerper is ook Hans Mezger, zoek de naam anders maar op, maar net zo legendarisch als Busso bij Alfa. 5. Bij de series werden maar heel weinig beperkingen opgelegd, net als in dit project. 6.

MINOR ELECTRIC DRIVE

TEAM ELEGANCE DESIGNING A COMPLETELY NEW ELECTRIC DRIVE LINE FOR A 1975 DAF 66. WE WANTED TO COMPLETELY REVISE THE ENTIRE DRIVELINE FOR A 1975 DAF 66. WE FELT THAT THE 35 KW MOTOR WASN’T ENOUGH TO KEEP UP WITH MODERN DAY TRAFFIC, WHICH IS WHY WE WANTED TO USE A SIEMENS AC 3 PHASE MOTOR. THIS WOULD INCREASE THE POWER TO 90KW AND WOULD GREATLY IMPROVE DRIVABILITY.

Our existing Lithium iron phosphate battery pack was old, heavy and had quite a few broken cells. It was also difficult to work with in terms of packaging and couldn’t reach the voltage required to drive the new motor. This is why we decided to design our own brand new Lithium ion battery pack. We chose the INR18650-25R cells manufactured by Samsung SDI. They allow for faster charging, and deliver a lot of power compared to other 18650 cells. Going from Lithium iron phosphate to Lithium ion meant we had to buy a new battery management system (BMS) as well. This allowed us to add DC fast charging, making the most of our new battery pack. With the original CVT being designed over 40 years ago, the efficiency is not up to today’s standards. Our goal is to make the DAF 66 future proof. Which means that the DAF 66 also works in the future. It had a energy efficiency of a mere 71% and it produced a lot of noise, which was very apparent since it was no longer drowned out by the engine

FONTYS UNIVERSITY OF APPLIED SCIENCES

sound. Considering this and the fact that it wouldn’t be able to handle the torque from the new electric motor, we had no other choice than to look for alternatives. This alternative was found in a Volvo 340 manual transmission. It’s main advantage is that it would fit without having to do major structural changes to the chassis. It also comes with an integrated differential which is beneficial in terms of packaging. To achieve the optimal balance between top speed and acceleration, we chose second gear as our fixed gear ratio. Because of the broad operational rev range of our electric motor, there is no need for a changing gear ratio. Starting point. With Low emission Zones (LEZ) increasing in both number and size, Classic cars are prohibited from driving in more and more places. Local governments are banning classic cars from city centres in an effort to improve air quality. Should this trend continue, one might even wonder whether classic cars even have a future on any public road at all.

As students at Fontys university of applied sciences, we take this problem to heart and try to solve this during our minor electric drive, which is why we have formed Team Elegance. Team Elegance believes that classic cars are a part of history that should be persevered, not just in museums but also on the open roads and even inside city centres. Our vision is to be able to enjoy classic cars on any public road without harming the environment. We try to achieve this by fitting classic cars with fully electric drivetrains, with our 1975 DAF 66 paving the way for other (future) classic cars.

MINOR BE CREATIVE

FLORAL FLOW (GLOW) GLOW’S ASSIGNMENT IS TO COME UP WITH A LIGHT ART INSTALLATION THAT WILL BE INTERACTIVE AND LIVELY FOR THE VISITORS TO THE EVENT. IN ADDITION, IT IS A BIG WISH TO SAVE ENERGY ON THE INSTALLATION.

Floral Flow is the name of the GLOW student project of 2019. This project is carried out under the minor ‘Be creative’. The student team consists of 4 Mechatronics students and 1 Electrical engineering student. In the first week of the Minor, the Student group: followed a boot camp called ‘blikwisseling’ where the team learned different skills and theory. By learning these new skills, the students are now able to approach a problem with a more creative mindset during the project. Meeting other students was also valuable during this week. The four weeks after the boot camp, the group was introduced to the requirements and wishes of the client and brainstormed possible solutions for the problems. Many brainstorming sessions have led to the generation of 85 ideas. These ideas were then minimized to the best 3 ideas. The client then chose the best idea based on a rough sketch and the explanation of the idea: The idea is to make a few flower boxes with beautiful blooming flowers. They don’t just bloom, water is what these flowers need to grow and light up. Visitors must pump water out of ‘the dommel’ (a canal in Eindhoven) in a big reservoir. The water flows from the

24

reservoir to the water wheel that stands next to the flower pots. Rotating the water wheel eventually causes opening of the flowers. In addition to opening the flowers, the entire installation will also be light up.

With our installation we hope to entertain GLOW visitors and introduce them to light art. We also hope to contribute to greater awareness of GLOW so that the number of visitors increases every year.

A prototype was made from a rough sketch. A prototype is a small model of the final product. Before the prototype can be made, various 3D models and electrical diagrams have been drawn. We also made a material list with all the materials that we needed.

FONTYS TUTOR Harold Benten, h.benten@fontys.nl

To come up with ideas for design, we started brainstorming about various hobbies of our group members. We have also worked with post-it cards to come to our idea.

HANDEX CREATED AS A REHABILITATION DEVICE, THE EXOSKELETON GUIDES THE PATIENT’S HAND, IN ORDER TO REGAIN THEIR FINGERS MOBILITY AND STRENGTH.

The Handex Exoskeleton Therapy Hand is a rehabilitation device created with the purpose of helping people regain their fingers strength and mobility, following a spinal cord injury, stroke or other medical condition that results in the loss of finger mobility. In some of these cases, several arm muscles are still functional, and their activity can be sensed and translated through the exoskeleton into movement.  Built as an anatomically miming structure, the exoskeleton must fit on the hand of the patient, without suppressing the natural movements of the fingers. As potential muscle sensor, surface EMG sensors are taken into account, especially created to record the electrical potential generated by muscles. The muscle cell activity of the forearm/bicep muscles will be sensed, filtered and conditioned, and linked to different hand positions.  The signal will be processed using a microcontroller, such as Arduino, and

FONTYS UNIVERSITY OF APPLIED SCIENCES

sent to the hand actuators, in order to create the desired finger movement. The Exoskeleton Therapy Hand will have two modes – auto mode and manual mode. The auto mode will be triggered by the EMG signal sensed at the level of the muscle. This will activate the system which will guide the patient’s hand in a full fist flexion, followed by full extension and ending in a relaxed position of the hand.  In the manual mode there are two functions. The first function will be controlled by two buttons on the main PCB. By pressing one of the button, the motion of flexing hand will start; by pressing the other button, the motion of extension will start. The second mode will be controlled by using UART communication from computer, commands can be send towards the microcontroller. These commands will be converted by the microprocessor into

movements of the exoskeleton. The most important thing taken into concern for the exoskeleton is safety. For the exoskeleton, multiple methods are used to insure the patient’s safety. When the exoskeleton attempts to over extend or over flex, the mechanical joints will be stopped by both software and mechanical protection.

MINOR ADAPTIVE ROBOTICS

A ROBOT (ARM) WITH CHARACTER A ROBOT (ARM) WITH CHARACTER IS PART OF THE CLOSE ENCOUNTERS PROJECT. THE TOPICS IN SCOPE ARE RELATED TO HUMANROBOT INTERACTION ON THE WORKPLACE AND OTHER ENVIRONMENTS. It can be pointed that collaborative robots are in their infancy stage of development with regards to the pure psychological factor exerted on their human collaborators. The majority of the products on the market have capabilities and movement patterns, inherited from industrial robots which may convey a feeling of danger to the operator. Thus, a novelty manner of interaction should be in place. The main research problem of A Robot (arm) with Character project is: how can collaborative robotics be implemented in a way that they are presented to the end user as a safe, trustworthy and comfortable to work alongside with. The goal of this project is to develop a software package in ROS, which controls a robotic arm (UR5). The robotic arm should be able to move and interact with a human participant. The interaction revolves around a simple game of dice between the arm and the human. The arm should behave in such way that the human perceives it as a sentient entity with emotions and personality. The robotic arm should demonstrate its sentient capabilities, character and its understanding of its environment

26

only by the means of emotion expressed through motion. The project group is the first, working on the software package for A Robot (arm) with Character Project. We will lay the foundations for further development The project might be of interest to companies and clients in the cooperative robotics field. Through the interactions and movement patterns shown in the game between the robot and the human participant, deductions can be made how to implement better, safer and comfortable to work with co-bots.

SCOUT GREENHOUSE IN DE VRAAG NAAR VERDERE OPTIMALISATIE VAN DE PRODUCTIE VAN GEWASSEN IN KASSEN IS HET PROJECT SCOUT GREENHOUSE (SENSORIC DATA CATCHING OF HIGHLY USEFUL TERABYTES) ONTSTAAN.

Dit project is opgezet om aan de hand van micromanagement de opbrengsten in kassen te optimaliseren. Binnen dit project is het doel om naast de focus op de opbrengsten te hebben, ook te kijken naar de duurzaamheid van het verbouwen van deze gewassen. Om het voor het project eenvoudiger te houden, is er aangenomen dat het over tomaten gaat, waarbij dit in een later stadium aangepast zou kunnen worden naar bijvoorbeeld paprika’s. De groei van een tomatenplant is afhankelijk van verschillende invloeden, zoals temperatuur en vochtigheid samen met de juiste hoeveelheid voeding en goede verzorging. Om de optimale groei te houden, moet de boer de groei zelf nauwlettend volgen, inclusief alle externe variabelen die van invloed zijn op de groei. Om dit met een betere efficiëntie en nauwkeurigheid te doen, wordt er een prototype van een industriële robot ontwikkeld die autonoom deze metingen kan uitvoeren. Om dit probleem aan te pakken is er gevraagd naar een systeem, die een camera naar verschillende tomatenplanten kan bewegen, die op verschillende hoogtes en posities staan. De opdracht voor dit project kan opgesplitst worden in twee onderdelen. De lift die al reeds opgeleverd is, en verder afgemaakt is. Dit is de

FONTYS UNIVERSITY OF APPLIED SCIENCES

hoofdopdracht van dit project. Het subdoel is het opleveren van een mobiel onderstel waar deze lift bevestigd kan worden. Hierdoor kan het hele systeem de camera plaatsen in de x-, y- en z-as. Het eindproduct is een rijdend platform met een lift waarop alle benodigde sensoren gezet kunnen worden. Het is gelukt om de lift volledig werkend te krijgen. Ook voldoet het platform aan alle eisen met betrekking tot afmetingen, draagvermogen en veiligheid. Door het uitvoeren van de boven genoemde activiteiten, heeft dit project een antwoord gegeven op de hoofdvraag: Hoe maak je een robot dat in staat is om in een kas te rijden en metingen uitvoeren aan tomatenplanten? Het is gelukt om een rijdend platform te bouwen dat geïntegreerd is met het bestaande liftsysteem. Op dit moment is de robot voorbereid voor de implementatie van software die autonoom rijden mogelijk maakt.

LET’S MOVE IT MOBILE ROBOTS ARE USED MORE AND MORE USED IN A MANUFACTURING OR WAREHOUSING ENVIRONMENT. CURRENTLY THERE ARE DIFFERENT SUPPLIERS OF THESE TYPES OF ROBOTS LIKE OMRON, KNAPP, ETC.

Within the ‘Let’s Move It project’ an automated storage system/robot has been developed which can take boxes containing e.g. screws or 3d printed parts from a shelf and hand it to a robot. This storage system is part of the lectoraat’s smart manufacturing environment in which robots from different manufacturers can take goods and deliver them to a robot cell or a worker. Also a lift system has been developed to take goods from robot height to a UR5 robot that is placed on a table. The boxes could not be transported between storage system to the UR5 robot. For this purpose a MIR robot is available which needed to be made able to take boxes from the storage system to the UR5 cell and back. A transport system needed to be developed that takes in several boxes and can deliver them at several places in the correct order. This system was designed, build and tested in the actual smart manufacturing environment within the lectoraat.

A complete system of machines that are working together. Before this project the machines were working only standalone. The result of this project is the MiR100 working together with the automated storage, docking station and the UR-5 Robot arm. This is for the client beneficial because this project is part of a collabaration between other universities. This way we can develop solutions to work together with mutiplite robots in an SME manufacturing environment.
