CM1 Smart Fridge Everyone’s kitchens can be busy places and we like to leave notes for people, to have a calendar shared with others, to show photo’s, postcards, drawings and memories made together. We like to check news and weather on the way out in the mornings and use the internet for recipes, videos and just entertainment in the evenings. This fridge offers a new way to do all of these by taking a device we’ve all got already plugged in 24-7 and opened 15-20 times a day to bring all these features to your kitchen.

Concepts & Development Prevent twist by creating grooved shape in the extrusions and countersinking fixing methods to eliminate pontential harm to user
Deciding on fixings A clevis pin & r clip fixing method was chosen, as it removes the need for the fixing method to be maintained since it does not gradually wear like a nut & bolt. 16
Calculated lengths of extrusions needed in telescopic joints to create goal sizes required and ensured it complies with all relevant British Standards. BS 8462:2005 & BS EN 748:2013
1800N
*ANSYS Simulation* British Standards states that a crossbar should not deform more than 10mm when tested under 1800N. By including a factor of safety of 2, max deformation was 5mm. Ansys (FEA) was used to calculate and find the ideal crossbar structure. It was found that having corners of the crossbar intruding into the centre crossbar by 1590mm, resulted in a max deformation of 4.8mm, which met the specification. 17

PetRo
The earliest version of the PetRo concept was in 2000, a caltrop shaped omnidirectional modular robot. The (long-term) aim of PetRo was to reach a throwable and self-assembling design, which could be used for a wide range of applications such as search & rescue and inspection & surveying. The initial ideas and developments were conducted in 2000-2001, since then prototypes I, 2 and 3 have been developed. We are currently developing the concept into a series of demonstration prototypes. The main motivation behind the project was the need to deliver a robotic platform that allows for field applications away from controlled environments, requiring both reconfigurability and high-mobility. We also wanted to minimise the handling and care required by the robot, with the long-term aim of a throwable robot.
23
3D printing and testing parts allowed us to improve their overall strength and the types of fits they had with other components, subsequently allowing the testing of selected stepper motors and drivers. Other things we began to test were the end plate communication, specifically how each module will communicate with each other. We decided to use asynchronous communication to send data between the two modules since they will not be on the same local clock, so this method will help to synchronise the start and end of each byte sent.
I have been working on the ‘Petro 3’ modular robot prototype, helping to lead a design team focusing primarily on the mechanical and control systems of the robot. To create the prototype, we used a variety of CAD software. The project enhanced my skills in technical writing of documents, using 3D CAD models and creating complex animations and renders. We’ve presented the prototype robot at the ‘RO-MAN’ conference in Edinburgh, U.K. 24

Coupling
A
A modular approach offers many benefits. The availability of redundancies allows damaged modules to be discarded, thus improving reliability. This redundancy is also a contributor to addressing a potentially limiting power supply, by allowing the re-distribution of power amongst modules. Another benefit is the adaptability of the robot, which goes as far as reconfigurability in terms of overall architecture and thereafter offer variability in gaits and motions available. 26

A third benefit, specific to pet application, is the metaphoric growth potential the robot possesses, achieved by adding modules to the assembly - an interesting fact from a commercial perspective. The bi-modular configuration yields a dog-like appearance, inspired by the body language and expressions from dogs’ body movements. We see this language as a means to provide feedback that is intuitive, natural and can potentially reinforce an empathic connection between user and robot in an analogous pet-owner relationship.
A screenshot of the animation of PetRo expressing fear (Shoulder in green, Hips in red).
We focus on the following emotions: anger, curiosity, disgust, fear, happiness, and sadness. All, but one (curiosity) are basic emotions, evidenced by the functional neuroanatomy of the brain. Contrary to what has been said in literature, we do not consider surprise as a basic emotion. Furthermore, while curiosity is not a basic emotion, we have added it due to its highly relevant proposed functions of the robot. We also include the following artificial moods: ready and low--power. 28
PetRo has multiple applications including companion pet, search and rescue, and in general applications where it is difficult to predict the theatre of operation in which the robot will be used.
PetRo’s Multimodal Emotional Language was presented at IEEE RO-MAN 2016, The 25th IEEE International Symposium on Robot and Human Interactive Communication.

Six Northumbria University students, including myself, created Woodcut and Co, a start-up wooden gifts manufacturer and retailer located in Newcastle-upon-Tyne. With an initial cash injection of ÂŁ200, we were able to fund our business start-up without any external investment, making this business idea viable whilst still attending university. By using a laser cutting machine and locally sourced wood, we created our product range. As well as our leading classic and seasonal product collections, we also aimed to offer a unique, personalised product service to customers, exploiting a niche in the market compared to other sellers. 32

The 9004 Britax Rear Combination Lamp has been a widely sold rear light all over the world for the last 20 years, catering to commercial vehicles as their go to aftermarket lamp. As the years have passed, technology has changed and so has the company that owns the 9004, creating a need to redesign the product. The new design incorporates the latest in lighting safety and technology, addressing issues such as suitability and technology trade-offs, reduced product depth and has helped to secure a promising future for not only the product, but for the company as well.

Company Background & Takeover Britax, a car safety equipment company, which has been in business since 1939, was officially taken over by ESG in April 2017. ESG is the world’s largest manufacturer of commercial and emergency vehicle warning and safety products. Their aim since taking over Britax is to rebrand all of their products to their main commercial brand, ECCO, and redesign products to better meet the their brand and values, such as product quality, design and innovation.
Research & Consulting Experts Initial research and consulting experts from CS Auto Electrical Parts UK helped to find out users key needs & wants from the 9004.

C o nc e pts & D eve lop m e nt Before major factors like cost and viability were introduced, a concept classification tree and mind mapping were used to introduce every possible idea and new technology that could be applied to the 9004. A morphological chart followed, creating individual concepts from these ideas.
LED Technology was chosen to be taken forward after all factors were considered. OLED Technology will be considered in the future when it becomes more viable.

Sweeping Indication
Casing Development Case fixings for the base and lens were then developed, identifying that no maintenance was required for the new technology. Sustainability and end of life considerations were used to help to also choose a fixing. After testing and more research, the most effective snap joint was used in the lens and used the base as a lip for the snap feature.
The selected snap joint can still be molded using just a two part mould and doesn’t require any extra moulding actions Sweeping indication fully activates 90ms before a standard halogen bulb

A global game of tag that can be played wherever, whenever Tag, also called touch or tig, is a children’s game in which the player who is “it” chases the other players, trying to touch one of them, thereby making that person “it.” I knew that I wanted to take my interests further into wearable tech, so I decided to create a game of tag on a much larger scale. The idea was that the game would be played throughout your everyday life, so whether you were at work, or at college, you would still be playing and could be tagged at anytime.
New Jersey, US 45
P roto ty p in g & Test i ng The idea for my first prototype was to use a micro-controller to record the data from each player. Capacitive touch sensors would be placed in the shoulders of each player, and would be used to detect users touching one another, sending that data to the cloud. The game dashboard would then ask the cloud for data, with the data received back being sorted and displayed on the page to the user. Capacitive Touch Diagram Waiting for player number...
