Researchers at the University of Southern Denmark have modified a Wii remote control so that it can control an industrial lawn mower.
"The Casmobot project is about making grass cutting more efficient," said Kjeld Jensen, a robotics researcher at the University of Southern Denmark who developed the system.
It uses a standard Wii remote control that communicates via Bluetooth to a computer and robotics module built into the mower. Actions of the mower are matched to tilt actions of the remote. For example, if you tilt the remote down the mower moves forwards, tilt is up and it moves backwards and so on.
The Wii-mote can be used to control the mower manually or in computer-assisted mode, where the mower is guided around the edge of the area to be cut and then left to finish the job automatically.
