This is the fourth robot that our team built at Marista Sant´Ana School, in Uruguaiana - Brazil. The team members include Eduardo José Bruxel de Sá, Fernando Bruxel de Sá, Lucas Dias da Silva Predebon, Luiza Sanchotene Ceolin, Raquel Forgiarini Saldanha and Younes Maia Younes.

We implemented a holonomic drive-train, capable of moving the platform in any direction (even in diagonals) without changing the orientation of the wheels. The motors are controlled independently by 4 National LMD18200T MOSFET H-Bridges. The robot is controlled by a MSWlogo GUI running on a windows PC. Radio link range is 150m. The voice recognition system allows 3 different operators to control the system using their speech. Accuracy is about 95%.

The robotic arm allows moving small objects (the arm claw opens to 5cm). The maximum lifting capacity is 500 grams. We designed our own board to control all 5 motors present on the manipulator. A CMUcam allows the system to track objects by their color. The robotic arm is capable of picking up these objects automatically. A 16x2 character LCD display system information.
