Sword-wielding, Tennis-playing WiiBot
You knew it wouldn't be long before someone pulled this off. Wonder if there's a blood-thirsty lawyer or three at Nintendo that might have issues with this small "mod"?
"The idea was to take one industrial robot, add a laptop talking to a WiiMote, strap on a tennis racket, have it follow the swings that the user makes, and do it all in a few hours on a Saturday so we could get back to our busy schedules. Of course we had to put on a sword too, and if there was time, maybe an Airsoft gun. Also, we wanted it to fight people, but you can't have everything."
Check the vid - pretty cool. Gotta get me one of those industrial robots for when the dog gets out of line. Heel, boy... I said HEEL!
