How to make a bike-like vehicle with legs instead of wheels?
For Halloween, I'm going to be riding a unicorn, and the unicorn is basically two bikes but with leg-like poles instead of wheels. This is basically like a hexapod robot, but with four legs instead of six and pedals instead of motors. I already know where to get the parts and stuff, but need to figure out how to make a working leg mechanism. Anyone have any ideas on how to make it walk?
