The Swirling Brain sent us a link to a really cool video of Anybot's dynamically balancing walking robot, named Dextor. The robot actually balances much like a human, instead of using the more common Zero Moment Point (ZMP) algorithm used by robots like ASIMO. Paul Graham wrote a detailed blog post about about Dextor's first first successful walk. Dextor is a biped robot about 5'10", weighing in at 135lbs. The robot uses air cylinders which provide a spring-like quality similar to human muscles, allowing the robot to achieve more life-like movement.
