I youtube'd arduino and found this great video of a hexapod and thought it was intreasting.
The second video is a slightly differnt robot (i think) but the same idea.
I also have a question if anyone can anwser, i know the picaxe 28x1 is only able to control 2 motors with forward/ backwards. but this is a hexapod. Is it just that the servo cables are Y-splitted and the front and rear legs are run off the controller track? Or can the arduino control more servos. a little confused
