Foot shock absorbing structure of robot

Abstract

The invention discloses a foot shock absorbing structure of a robot. The foot shock absorbing structure comprises a foot joint, wherein a leg joint is arranged at the top of the foot joint, a shock absorbing pad is installed at a rotary shaft of the leg joint and comprises a lower partition layer steel plate and an upper partition layer steel plate, an elastic rubber ring is arranged between the lower partition layer steel plate and the upper partition layer steel plate, pressure sensors are arranged on two sides of the elastic rubber ring, a force measuring sensor is arranged at the lower portion of the foot joint, a foot shock absorbing ring is arranged at the top of the force measuring sensor, compression pieces are arranged at two ends of the foot shock absorbing ring, an elastic compression spring is installed between the compression pieces, and resetting of the foot joint is achieved through the elastic compression spring. Adjustment and replacement are facilitated, the walking stability of a foot mechanism is improved, an activity angle range is large, and the foot shock absorbing structure is novel in design and is a very good innovative scheme.

Description

technical field [0001] The invention relates to the field of intelligent robot control, in particular to a foot shock absorbing structure of a robot. Background technique [0002] A robot is a machine device that performs work automatically. It can accept human command, run pre-programmed programs, and act according to principles formulated with artificial intelligence technology. Its mission is to assist or replace human work in jobs such as manufacturing, construction, or hazardous jobs. The robot arm generally adopts a space open-chain linkage mechanism, in which the kinematic pairs (revolving pairs or moving pairs) are often called joints, and the number of joints is usually the number of degrees of freedom of the robot. According to different joint configuration types and motion coordinate forms, robot actuators can be divided into rectangular coordinates, cylindrical coordinates, polar coordinates and joint coordinates. For anthropomorphic considerations, the releva...

AI Technical Summary

Problems solved by technology

It inputs electrical signals, and outputs linear and angular displacements. During the driving process of the robot, all the gravity comes from the feet, which carry all the movements of the robot. However, the shock absorption performance of the feet is not good at present. , affect the movement related to the robot, easily cause damage to the parts, there are deficiencies, and cannot meet the needs of development
