Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the first method cannot effectively avoid the singular position when dragging the robot because it does not need to further plan the speed of each axis joint of the robot.
The second method directly calculates the delivery position of each joint axis of the robot from the obtained sensor torque, so the accuracy of the robot's dragging and teaching is relatively poor
The third method does not implement trajectory planning through the acquisition of the speed of each axis joint of the robot. Therefore, the accuracy of the robot’s dragging and teaching is relatively poor, and it is difficult to avoid the singular position during the dragging and teaching process.

Abstract

The invention relates to the technical field of robot control, in particular to a method and device for controlling a robot. The method for controlling the robot comprises the steps of setting a tracking period; collecting force sensor information in the tracking period, obtaining a tracking position of each pivot joint of a robot multiaxis mechanism according to the collected force sensor information, wherein the tracking position is a position of each pivot joint of the multiaxis mechanism in a next tracking period, recording the tracking period and the tracking position, performing track planning on the tracking position in the tracking period, sending the track planning to a servo control system, and controlling each pivot joint of the multiaxis mechanism to move to the tracking position. The embodiment of the invention further provides the device for controlling the robot. The robot controlling process is higher in precision and better in sensitivity.

Description

technical field [0001] The invention relates to the technical field of robot control, in particular to a robot control method and device. Background technique [0002] In the prior art, in the robot drag teaching method with a force sensor at the end, there are usually the following three processing methods. The first method is to obtain the sensor torque to obtain the end speed of the flange tooling of the robot, and the obtained The torque and the end speed of the flange tooling are processed as a PID (proportional, integral, differential) control loop, and then the sending position of each axis joint of the robot is obtained, and the function of dragging and teaching is realized. The second method is to directly convert the acquired sensor torque through the dynamic equation to calculate the delivery position of each joint axis of the robot. The third method is to directly plan the trajectory of the end of the flange tooling of the robot by the obtained sensor torque, an...
