Abstract – this article reports the experience of the development of a robot dancer during a teaching activity and the prominence obtained by him later in a robotics Tournament culminating with winning the second place in the ITR 2018 (International Tournament of Robots). First is the motivation for building the robotic prototype as evaluative activity to a course of integrated course to high school, as well as the importance of educational Robotics entered the course through this activity. The work deals with the experience of the students during the construction of the robot and the participation in the competition. The robot was built with recyclable materials, a simple hardware and programming if you’re using Arduino technology. In the final considerations is presented the improvement achieved in the educational performance of students involved as well as the awards achieved by the team of students. Keywords – teaching activity, robot, dance, tournament experience.

Experience of educational robotics applied to robotics tournament
I. INTRODUCTION Currently search for learning environments more and more dynamic and interactive, are recommended courses models that allow the learners greater contact with technology [1]. To this end, it was proposed in class of Microprocessor Systems from third year electronics technician course integrated into the high school of XXX the construction of robots themed (application) free, since to use as the Arduino microcontroller platform [2]. Among various designs chosen by the students, he obtained the idea of a group of five students to develop a robot, or better, “the girl robot” that could play the popular Brazilian rhythm choreography, funk, through their movements. The project of students at first did not have any pretense of participation in events, internal or external to the institution, but only meet demand proposed by the teacher of the discipline mentioned. By means of this activity was possible to observe that the educational robotics has a very important feature that is to offer the learner the option to set up and program your own robotic system, through their comments and your own practice [3], that is, a search for learning and research, these characteristics that favor a really significant learning [4].
Along the robotic prototype construction apprentices were getting grilled about the existing robots dancing competitions in Brazil and then came the desire to improve the project in a way that makes it competitive enough to participate in one of these events. In addition, what made this project so interesting was the fact that the robot dance a way to allow the expression of creativity, always present when it comes to technology and robotics. In addition, robots dance to providing fun and interaction between people and robots, through knowledge of the operation of sensors, microcontrollers and actuators [5].
II. CONSTRUCTION OF THE ROBOT A. The physical structure and the mechanical part The girl robot, affectionately dubbed by “RobôNita” in allusion to the famous Brazilian funk singer Anita, was thought to move very flexible. It would be necessary for this purpose to be built of a light material, yet tough to be transported to events. Couldn’t be too big, should allow the movement of the knees, hips, butt, head and arms. Soon, we opted for the construction of a kind of Tin doll, which can be seen in Figure 1, which was essentially built with recyclable materials: can of soda, sponge, steel ladle, spoon, pieces of CDs and foil. For the construction of the eyes of “RobôNita we used two LEDs (light emitting diodes) in blue and the mouth an aluminum spring, thus setting a friendly face for your presentation.
