Abstract

The invention discloses a bionic mechanical leg joint driving transmission device. The bionic mechanical leg joint driving transmission device comprises a driving unit component, a power output shaft,a transmission rod and a joint control system which are connected in sequence. The power output shaft and the transmission rod transmit power output by the driving unit component to the joint controlsystem. According to the bionic mechanical leg joint driving transmission device, a multi-linkage mechanism is adopted for transmission, torque output by the driving unit is transmitted to a joint through the multi-linkage mechanism to achieve driving of the joint, and the bionic mechanical leg joint driving transmission device has the advantages of being small in size and large in bearing forceand also ensures the compactness and attractiveness of the leg structure.

Description

technical field [0001] The invention belongs to the field of bionic robots, and more specifically relates to a leg joint driving and transmission device of a bionic mechanical leg. Background technique [0002] At this stage, bionic robots have become one of the most active research fields. According to the different forms of motion, the structure of bionic robots can be divided into three types: wheeled, crawler and legged. Compared with wheel structure and crawler structure, legged structure robots have better environmental adaptability. Robots with bionic mechanical legs can move on rough terrain such as potholes, gravel, sand, grass, etc., and have important applications in material handling and combat assistance, and have broad application prospects. [0003] In addition, the form of bionic mechanical legs can also be applied to helicopter leg landing gear. Compared with the limitations of the two conventional landing gears of skid type and wheel type, the landing gear...
