Here's a robot video that I found interesting:
To demonstrate the possibilities of the Kinect system, Microsoft put together some boxing robots - basically borrowing from the Rockem Sockem Robots created decades ago by Marvin Glass and marketed by the Marx Toy company.
The Microsoft implementation was OK, as far as it goes, but didn't really capture much of the excitement, noise, and energy of other boxing robot demonstrations. It was like Microsoft understood the concept logically, but their heart wasn't really in it.
To make matters even more difficult, the demonstration took place in a tent that was open to ambient sunshine on several sides. That resulted in the Kinect sensors being flooded with light, both visible and IR, sometimes during the day. While I was watching, several times over the three days I was at Maker Faire, the system had difficulty in locking in on the operators - typically young kids lined up for a chance to try their skill. Of course this wouldn't be a problem for systems setup indoors, or for Kinect units operating in your living room.
