Soccer A robot - overview
Features
This kit enables the user to build a soccer robot, which can be used for RoboCup Junior Soccer (RCJ) Lightweight competition. This kit is designed for future enhancements. Robot's features:
- Arduino compatible.
- 4 omni-wheel drive. It can move in any planar direction, rotation around Z axis at the same time.
- 3 composite line sensors.
- 4 lidars (lasers).
- CAN Bus architecture.
- A parformant IMU Bosch BNO055 (accelerometer, compass and gyroscope).
- eFuse, protecting microcontroller's voltage input.
- 3 powerful switching regulators, for future enhancements.
- Digital voltmeter.
- 6 switches.
- Bluetooth Classic, Bluetooth LE, and WiFi.
- 2 user definable LEDs.
- Motor controller for 4 motors ,stronger than the ones in this kit, for future enhancements.
- 8x8 3-color display.
- Sensor for RCJ active IR ball.

Target usage
2 robots per each of 2 teams are needed for RCJ Soccer Lightweight. A RCJ compatible arena and a RCJ active IR ball are also needed. Each team tries to score as many points as possible, pushing (or kicking) the ball into opponent's goal. The robots mustn't cross white border lines. They have to have idea where the ball is, where the goals are and, if possible, where they are. According to these data, they develop a strategy how to approach the ball from behind and then push it towards the goal. On the other hand, they have to defend their goal. The robots are fast. It is challenging to perform all the operation when they travel fast.
You will have to develop the program and later adjust robot's construction in order to achieve better results. This construction's intention is not to make a perfect robot, but to enable students to start building robots for RCJ competition.
This kit will be redesigned.
