Made a wooden ramp walker robot and making it walk forward and backwards. Because the feet are so poorly made it makes abrupt turns. Need to make some new feet.
Rotating head on a ball bearing seems to help stabilize the walker and keep it oriented but haven't really proved it - just seems obvious from observations.
