Most of the time we see a Wii mote controlling something tangible, it's more for entertainment value like an airsoft gun
. The Casmobot lawnmower, developed by scientists from the University of Southern Denmark, is actually quite useful if you loathe outdoor chores. It can be steered into grass-cutting action via the tilt of the controller synced with Bluetooth. Alternatively, you can drive it for a lap around the border of the yard and then put it on autopilot to mow inside the designated zone. We wouldn't run in front of it while its in motion, though, it's probably not as forgiving of interruption as a roomba. Researcher Kjeld Jensen also suggested applying the same technology to your grandmother's wheelchair, but we really don't think she'd appreciate that. See it for yourself in the video after the break.
