Building and programming walking robots is easier to start than it may seem, and lots of fun. You won't build another Boston Dynamics Big Dog or MIT Cheetah, but you can easily build a simple bipedal Bob robot, or make a stuffed toy sheep walk around on four legs. I'm going to show several robots that I have build, and give some hints for building your own.
