Abstract

The invention discloses a robot structure which can jump by imitating the leg shape of the kangaroo. A load is arranged on the frame, a knee joint of the robot is connected with the lower side of the frame by a holding frame. The knee joint of the robot is connected with the lower leg of the robot by a leg part axis. The lower end of the lower leg is the ankle joint of the robot; the sole is connected with the lower leg by the sole axis at the ankle joint, meanwhile the ankle joint is at the one-third position of the sole. The sole and the toes are connected by a toe axis, and the toe axis is arranged at the front end of the sole. One end of the lower-arranged spring is arranged at the back end of the sole, and the other end of the lower-arranged spring is arranged at the two-fifth position of the lower leg. One end of the upper-arranged spring is arranged at the upper end of the lower leg, and the other end of the upper-arranged spring is arranged at the half position of the frame. The power mechanism is respectively connected with the lower leg and the sole by an upper earring and a lower earring. The robot structure has the advantages of improving the jump efficiency of the robot and reinforcing the jumping ability.

Description

technical field [0001] The invention relates to a robot structure, in particular to a jumping robot structure. Background technique [0002] At present, the research on jumping robots is still in the research stage in the world, and only a few universities in China have carried out relevant research. In 1984, Professor M.H.Raibert of the MIT Leg Laboratory made a pioneering contribution. He designed the world's first single-legged robot that moves in a jumping manner, solved the problem of the take-off attitude control and foot positioning algorithm when landing, and conducted a series of simulation analysis and experiments under a simple model. [0003] The patent application number is 200710072236.6, and the patent application titled bionic locust jumping robot discloses a bionic locust jumping robot. It includes a body, a front leg support shock absorption mechanism, and a rear leg take-off mechanism; the front leg support shock absorption mechanism includes a sleeve hi...
