Let's Make Robots!

Have any of you seen this little thing? I was looking at it at the store and it looks awesome. The arms and legs are flexible; you can move them around and there don't seem to be any gears. I wonder if there is some sort of "tendon" thing going on. I want to try to hack one, but at $60, that's a bit much.

I pulled apart a robot dinosaur with a flexible neck and tail. Basically it used a setup similar to the cables on a bicyle used for brakes and to change gears. The cables were tensioned with a spring so that no damage was done if the limbs got stuck or were forced into different positions.

Ebay has it for roughly $8.50 here
