Abstract

The invention discloses a method, a device and a robot for adjusting the gain of a servo drive system of a transport robot, and relates to the technical field of robots. The method includes: driving the left and right driving wheels of the transport robot to run through the first and second servo drive systems, Determine the following error according to the running distance of the left and right driving wheels and the predetermined running trajectory; adjust the gain parameters of the position loop unit of the first and second servo drive systems according to the following error to reduce the running deviation. The gain adjustment method, device and robot of the present invention adjust the position gain of the servo drive system driving the left and right drive wheels based on the following error of the left and right drive wheels, so that the dynamic characteristics of the two independent servo drive systems are matched, and the The coupling adjustment of two independent servo drive systems improves the motion trajectory accuracy of the handling robot, and improves the stability and safety of operation.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a gain adjustment method and device for a servo drive system of a transport robot and a transport robot. Background technique [0002] The tide of the information age has promoted the continuous reform of the logistics industry, and robots and automation equipment are becoming a new force in the logistics industry. There are more and more applications of unmanned warehouses, and the handling robots in unmanned warehouses will be fully used for cargo handling. There are usually two driving wheels in the chassis wheel train of the handling robot, such as figure 1 As shown, a pair of driving wheels 01 and 02 are distributed on the chassis of the handling robot. The driving wheels 01 and 02 are driven by their own motors. The two motors rotate in the same direction and at the same speed to realize the straight forward and backward of the robot. High-speed rotation can realize the in...
