Problems solved by technology

[0002] Existing quadruped robots are usually driven by servo motors of parallel five-bar mechanisms. Frequent speed changes and reversing are required during the application process, and frequent speed changes and reversing are likely to cause problems such as impact and energy loss, and the cost of servo motors is relatively high. high
In addition, the existing quadruped robots cannot walk smoothly on the road with a certain slope, and usually need to adjust the gait of the robot, which increases the difficulty of control

Abstract

The invention relates to a normal-speed electrically-driven quadruped robot with an adjustable gravity center and a use method of the normal-speed electrically-driven quadruped robot. The normal-speedelectrically-driven quadruped robot with the adjustable gravity center comprises a machine frame, wherein front-part leg rods which are correspondingly driven by a first crank and rocker mechanism installed on the machine frame and swing in a front-back staggered mode are arranged on the two sides of the front part of the machine frame, rear-part leg rods which are correspondingly driven by a second crank and rocker mechanism installed on the machine frame and swing in a front-back staggered mode are arranged on the two sides of the rear part of the machine frame, antiskid foot ends are arranged at the lower ends of the front-part leg rods and the lower parts of the rear-part leg rods correspondingly, and a gravity center adjusting device is arranged on the lower part of the machine frame. The gravity center of the quadruped robot can be adjusted so that the quadruped robot can walk on the road surface with a certain slope conveniently and steadily.

Description

Technical field [0001] The invention relates to a constant-speed electric-driven quadruped robot with adjustable center of gravity and a use method thereof. Background technique [0002] Existing quadruped robots are usually used to drive the servo motor of a parallel five-bar mechanism. Frequent speed changes and commutation are required during the application process. Such frequent speed changes and commutation are likely to cause problems such as impact and energy loss, and the cost of the servo motor is relatively high. high. In addition, the existing quadruped robots cannot walk smoothly on roads with a certain slope, and usually need to adjust the gait of the robot, which increases the control difficulty. Summary of the invention [0003] The purpose of the present invention is to provide a constant-speed electric drive quadruped robot with adjustable center of gravity and a method of use thereof. The quadruped robot can adjust the center of gravity so as to walk relatively...
