E-2 is my first walker I built. He walks as he drags his lower body with him. I used a k'nex servo driver
to move his arms around. If I rearange his legs a certant way I can make him break dance! I got the parts for free,my friend gave me all the parts. The hard part was making the wheels attatched to his body. I needed to connect one part of the wheel holder to the other conection stick. If you have any questions email me at chrisam@sbcglobal.net
