Bionic Methods for Quadruped Robot Design and Control

Bionics has greatly improved the development of quadruped robot, in the paper we propose three bionic methods for the quadruped robot. These methods have been used for control method design, gait design and control architecture design. The quadruped robot control method has been divided into two parts, because the four-legged animals change their trot speed by adjustment of step length in swing phase and maintain their balance in support phase; control architecture is derived from the four-legged animals nerve system; gait of quadruped robot is based on event driven, and its trot gait is the same as German shepherd. Simulations and experiments are performed, which prove bionics design to be realizable for the quadruped robot.
