A frog robot based on bionic design

Abstract

The application provides a frog robot based on bionic design, wherein a driving unit comprises an air pump, a big calf telescopic air cylinder group, a small calf telescopic air cylinder group, a push rod of the big calf telescopic air cylinder group is fixed to a hinge end of a hinge sliding block module, a big calf connecting rod of a leg unit is connected to a sliding block end of the hinge sliding block module, when the big calf telescopic air cylinder group is telescoped, the big calf connecting rod can be swung in a plane, rotating shafts at two ends of a reduction motor are locked with a small calf connecting rod, one end of the small calf telescopic air cylinder group is fixed to the small calf connecting rod, and the other end of the small calf telescopic air cylinder group is connected to a foot unit through a push rod, when the small calf telescopic air cylinder group is pushed, the body can be kicked on the ground, a control board output end of a control unit provides control signals for the air pump, an electromagnetic valve and the reduction motor, and an input end of the control unit is a power unit, the electromagnetic valve can control telescopic movements of the big calf telescopic air cylinder group and the small calf telescopic air cylinder group, the reduction motor can control rotation of the small calf connecting rod in a plane, and the air pump supplies air for a pneumatic system, and under the joint action of all parts, the body can realize jumping movement.
