Abstract

The invention provides a quadruped robot body posture control method and a quadruped robot body posture control device. The method includes acquiring robot body posture angle, a robot body posture angular speed and position coordinates of all leg ends of a to-be-controlled quadruped robot in real time; computing an angle of a leg end supporting plane of the to-be-controlled quadruped robot relative to a robot body plane on the basis of the leg end position coordinates; computing a robot body posture angle control quantity of the to-be-controlled quadruped robot on the basis of the angle, the robot body posture angle and the robot body posture angular speed; computing all joint target positions of the to-be-controlled quadruped robot on the basis of the robot body posture angle control quantity, and controlling all joints of the to-be-controlled quadruped robot to move according to all the joint target positions. The quadruped robot body posture control method has the advantages that the method can achieve real-time robot body posture control of the to-be-controlled quadruped robot, and the movement stability and the terrain adaptability of the to-be-controlled quadruped robot are enhanced, so that the technical problem that the movement stability of the quadruped robot is affected severely by the poor real-time performance of an existing posture adjustment mode is relieved.

Description

technical field [0001] The present invention relates to the technical field of robots, in particular to a method and device for controlling body attitude of a quadruped robot. Background technique [0002] Theoretically, quadruped robots can adapt to all terrain environments that humans can reach without causing obvious damage to the terrain, which has great research value and market prospects. The movement of a quadruped robot requires time and space coordination between the movement of the body and the movement of the quadruped end, and requires full feedback of its own state information and full perception of the surrounding environment and terrain information, which is a very complex and demanding task. motion trajectory planning and real-time control process. Keeping the stability of the fuselage is the prerequisite for the movement of the quadruped robot, which requires the control of the attitude of the robot's fuselage. [0003] Quadruped robots mainly use walk gai...
