Abstract

The invention discloses a three-joint bionic mechanical leg with autonomous hydraulic distribution power. The three-joint bionic mechanical leg includes a thigh, a calf, a foot, a connecting frame, ahydraulic power system and a control device, and the connecting frame, the thigh, the calf and the foot are connected through joints in sequence. The bionic mechanical leg is fixedly connected or disassembled with a bionic robot through the connecting frame, and the hydraulic power system is arranged on the thigh and / or the calf and / or the foot. The control device is arranged on the thigh and / or the calf and / or the connecting frame and / or the foot. The three-joint bionic mechanical leg with the autonomous hydraulic distribution power can be quickly and fixedly connected and disassembled with the bionic robot, the torque is larger, and the operating control is simpler.

Description

technical field [0001] The invention relates to a bionic robot, in particular to a three-joint bionic mechanical leg with autonomous hydraulic distribution power of the bionic robot. Background technique [0002] Compared with wheeled and tracked mobile robots, bionic robots only need to touch the ground at discrete points when moving, can cross larger obstacles, and have stronger adaptability to complex terrain, and the legs of bionic robots can have multiple degrees of freedom. The movement flexibility and performance are greatly enhanced, and the body balance can be maintained by adjusting the angle of the supporting legs and the foot landing position, which is not easy to tip over and has high stability. In the future, bionic robots will have broader application prospects in life services, pipeline maintenance, flood fighting and disaster relief, film and television performances, security and military affairs. [0003] For the key component of the bionic robot—the bioni...
