For the past two years, our robots utilized an ARM microcontroller to communicate with the servos. For 2013, we are going to update this system big-time with these new features:
- multi-channel communication to servos (allows to talk to torso, left and right leg independently for increased communication speed)
- on-board 9 axis IMU
- two ARM M4 microcontrollers, one to handle the IMU and one to handle servo communication and motion execution
- up to 5 buttons and LEDs for manual control of the robots
- piezo for simple sound output (e.g. warning of low battery)
- imprinted logo 🙂
A first prototype was developed and successfully tested for the Berlin United Racing Team, an updated model has just been finished (picture below) and awaits final programming.
