This is a Kuka robot which is used for a range of industrial applications. Kuka makes a wide range of robots that can set you back anything from about $10,000 to a lot depending on the model that you choose. According to the guys at US Mechatronics, the Kuka is very responsive to serial inputs; so they did the logical and responsible thing. They hooked the Kuka up to a Wii Remote stuck a tennis racquet in its hand and hit some balls with the thing. Then being the wild and crazy guys that they are, they armed it with a broadsword and had some real fun.
