Abstract

The invention relates to a flexible external skeleton elbow joint based on aerated muscle, which is formed by two aerated muscles and one single-freedom rotation couple, to realize the single-freedom rotation of elbow joint. The invention uses aerated muscle as the element of joint to simulate the motion of muscle; the operator can wear said device, via the torque sensor mounted on the rotation couple to obtain the motion parameters, to operate the industrial mechanical hand. And it can control the air pressure of muscle chamber of joint to realize the force feedback. The invention has wide application, as the healthy return device of patient.

Description

technical field [0001] The invention relates to a flexible exoskeleton elbow joint based on pneumatic muscles, specifically a device with bionic characteristics, which can realize functions such as data collection of elbow joint movement of human upper limbs, force feedback signal generation, or assisting elbow joint movement. Background technique [0002] Exoskeleton technology is a new type of human-machine intelligent system control technology, which can be widely used in master-slave control of robots and medical rehabilitation aids for disabled patients. However, traditional exoskeleton systems usually use motors, hydraulic pressure or cylinders as control actuators, and their structures are complex. Contents of the invention [0003] The object of the present invention is to provide a flexible exoskeleton elbow joint based on pneumatic muscles, which is simple in structure, light, clean, reliable, has on-the-spot force feedback, and is suitable for master-slave contr...
