Two Kinects: surprisingly functional!

The Kinect is a really handy sensor for robotics.  We’ve been talking about having one Kinect mounted on the wall, to impose a simple global coordinate system; and separate obstacle detection Kinects mounted on each robot.

Surprisingly, multiple Kinects don’t seem to interfere with each other too badly–the Primesense dot detection is smart enough to preferentially recognize its own dots over the dots from the other kinect.
