A Nintendo Wii-remote along with bluetooth communication and an arduino gives us this magical cart with a wireless steering wheel.
These cool people are staunch DIY-ers and would love to see the community build more such vehicles.
The cart has two motors which use a chain to drive each of the rear wheels. A pair of H-bridge controllers let the Arduino interface with them. It’s also has a Bluetooth module that makes it a snap to pull accelerometer data from the Wii remote. The front end looks like it uses rack and pinion steering, but you won’t find a pinion or a steering column. Instead, a linear actuator is mounted parallel to the rack, moving it back and forth at the command of the Arduino.
The only downside I spot is the Battery life. I am sure that would be worked out too! Till then – Kudos to the inventors! I smell futuristic looking vehicle controls here.
