Abstract

The invention discloses a six-freedom-degree bionic mechanical arm based on pneumatic muscle. The six-freedom-degree bionic mechanical arm comprises a frame, a shoulder joint, an elbow joint, a wrist joint and a mechanical palm. The shoulder joint, the elbow joint, the wrist joint and the mechanical palm are sequentially connected and fixed to the frame. Moreover, the pneumatic muscle serves as a driver. Pulley components are used for achieving swinging and rotation of the joints. The six-freedom-degree bionic mechanical arm is small in size, high in flexibility and high in bionic degree.

Description

technical field [0001] The invention relates to the field of bionic robotic arms, in particular to a six-degree-of-freedom bionic robotic arm based on pneumatic muscles. Background technique [0002] At present, the mainstream mechanical arms are mainly driven by hydraulic components and servo motors. Traditional robots are high-power, high-response, and precise multi-joint systems. However, due to their high-quality, high-rigidity, and low power-to-weight ratios, their mechanical structures and driving devices are not suitable for contact operations with humans. human communication. Especially in the fields of bionic robots, service robots and rehabilitation robots, people have far greater requirements on the flexibility and safety of their arms than on their positional accuracy and carrying capacity. Nowadays, many enterprises and research institutes in China have developed bionic robotic arms with pneumatic muscles, which has greatly promoted the practical application o...
