[Brian] has brought together a powerful collection of hardware to build a robot. The end goal is to have a robot that’s controlled by a Wiimote.
The Wiimote communicates over Bluetooth with a Raspberry Pi, which is running a Python script. This script uses the CWiid Python module to communicate with the controller, and [Brian] has detailed instructions on getting the Wiimote working with a RPi. The RPi controls an ATmega based development board over SPI, which drives an h-bridge to control the two DC motors that move the robot.
[Brian]‘s code for this could be helpful for anyone looking to control their RPi with a Wiimote. Since Wiimotes and Bluetooth dongles are fairly cheap nowadays, this is a great way to drop in wireless control to any RPi project, or even to control your media center from the couch.
