Abstract

The invention relates to a biped robot lower limb mechanism, in particular to a biped robot lower limb mechanism driven hydraulically. The problems that an existing electrically-driven robot is small in loading capacity, low in specific power and poor in anti-interference performance are solved. The biped robot lower limb mechanism comprises a body, an oil distributor, a left leg and a right leg, the oil distributor is arranged on the upper surface of the body, the left leg and the right leg are arranged on the lower surface of the body side by side, and are of the same structure, and the left leg comprises a foot, a shank, a thigh, a hip joint forward swing hydraulic cylinder servo unit, a hip joint twisting hydraulic cylinder servo unit, a hip joint, a knee joint forward swing hydraulic cylinder servo unit, an ankle joint, two ankle joint hydraulic cylinder servo units, a hip joint side swing hydraulic cylinder servo unit and a body upper end swing connecting piece. The biped robot lower limb mechanism belongs to the field of robots.

Description

technical field [0001] The invention relates to a lower limb mechanism of a biped robot, in particular to a hydraulically driven lower limb mechanism of a biped robot, which belongs to the field of robots. Background technique [0002] At present, biped robot is an important subject of robot research. The biped robot has many joint degrees of freedom, complex motion forms, and very good flexibility. Compared with wheeled robots and tracked robots, it can adapt to various terrains and has a strong ability to adapt to the environment. Because the biped robot has a structure similar to the human body, it can replace people to complete many tasks and reduce the workload of humans, so it has a good prospect. Researchers at home and abroad have achieved remarkable results in this field. [0003] The driving method of biped robots has always been a research hotspot. At present, biped robots mostly use stepper motors, servo motors, etc. as the driving source of motion. The outpu...
