Beginning of video is 1/3 power, then full speed.
This is something from years ago that I forgot about. It was a prototype that I made for a toy. I like it a lot. :-) My daughter dug it out of a box yesterday and I remembered that I never showed it on here since it was secret when I built it. It can go forward/reverse and steer. There's a weird differential in it that makes the legs adjust the step length to the appropriate lengths when steering. The head wags side to side to help balance.
I 3D printed it on a BFB 3000 when the dinosaurs still walked the earth.
