Video of robot that balances an inverted pendulum

Eric says
Picture 1-99 This video shows a balancing robot moving with such fluidity and apparent emotion, that it almost seems alive.

Magnus Linderoth and Kristian Soltesz, students of Lunds University in Sweden, posted a video last winter of their "inverted pendulum" robot. I only found it recently because I saw a post in MAKE about double pendulums and searched for more in YouTube. The robot in the video tries desperately to keep a rod balanced in the air like a broomstick. As the researcher meddles with the robot, it responds with various tactics.
