This project is no longer maintained as I will instead focus on a Balancing robot kit, the Balanduino. For more information see the new repository: https://github.com/TKJElectronics/Balanduino and the Kickstarter campaign: http://www.kickstarter.com/projects/tkjelectronics/balanduino-balancing-robot-kit.

This is the remote control code, I use it to control my balancing robot. See code at: http://mbed.org/users/Lauszus/programs/BalancingRobotPS3/. The Arduino use the PS3 Controller Bluetooth Library for Arduino i created: https://github.com/TKJElectronics/USB_Host_Shield_2.0. It's pretty simple. It just sends the data via the serial port to the mbed, when then reacts to the commands.
