Principles Of robot Locomotion
If the robot has more than one leg there is the issue of leg coordination for locomotion. The total number of possible gaits in which a robot can travel depends on the number on legs it has. The gait is a periodic sequence of lift and release events for each leg. If a robot has k legs the number of possible events N is, accordant to [1], N=(2k-1)! ... Retrieve Content
