Research on Kinematics of Frog-jumping Robot

A mechanism model and a kinematics research method for bionic frog jumping robot were proposed. Based on the study of frog movement, a one-side jumping mechanism model for bionic frog robot was proposed. The kinematics equations of robot's hindlimb and forelimb during take-off and aerial phases were established, and its direct and inverse kinematics were studied through D-H method. The movement space of the robot's limb was analyzed. The robot's kinematics was calculated and the results coincide with the biologic experiment of frog, which demonstrates the feasibility of this bionic jumping model and validity of the research method. The conclusion will provide the theory for the development and control of the bionic frog jumping robot.
