Abstract

The invention discloses a leg bouncing mechanism for a frog-type robot. A tension spring is sleeved on a guide rod. The tail end of the spring is connected with a hip joint, and the upper end of the spring is connected with a slider. The guide rod, the slider, an oblique support rod, a thigh and joints form a crank slider structure. The leg part consists of a thigh, a shank, a connecting rod and joints; and the leg structure comprises the combination of two four-rod mechanisms. The stretch and contraction of the leg mechanism can be adjusted by controlling the slide of the slider on the guiderod. The sole of the robot is arc-shaped, and an arch support is arranged on the sole. The mechanical structure of the invention simulates skeletons of a frog, optimizes the leg structure, improves the utilization ratio of energy of power elements, improves the flexibility of the mechanical structure, and improves the jumping ability of the robot.

Description

technical field [0001] The invention relates to a robot structure, in particular to a frog-type robot leg bouncing mechanism. Background technique [0002] With the continuous development of robot technology, in the face of harsh environments and complex terrain, using the robot's bouncing function to enhance its ability to adapt to terrain and autonomous movement is a robot technology that has developed rapidly in recent years. Robots with bouncing performance are still in the research stage in the world, and only a few colleges and universities in China are conducting related research. Since the development of such robots is very difficult, many key technologies involved are highly confidential, so there is very little public information. [0003] Internationally, the earliest bouncing robot was successfully developed by Raibert in the Robotics Laboratory of the Massachusetts Institute of Technology in 1980. The robot belongs to the continuous jumping mechanism. Raibert a...
