This video makes me want to build robots. (2MB mpeg)

From David P. Anderson’s nBot Balancing Robot site. The Segway is amazing, but this is more inspiring.

Update: Michael Buffington wrote to remind me about the LegWay, a two-wheel balancing robot built from Legos. Also neat, but there is something about the videos of Mr. Anderson watching his little robot move around that’s just a fantastic display of everything I love about making stuff.
