The Wii Lawn Mower
At Southern University of Denmark, the robot laboratory "RoboCluster" is making grass cutting much easier than it is today.
Scientists at the lab have incorporated a robotics module into a standard slope mower, which enables it to be controlled with a Nintendo Wii Remote.
What's more, the modified mower (called Casmobot) can also mow all by itself. Just drive around the area you want cut with the Wii Remote, and Casmobot will take care of the rest.
