Abstract

The present invention is applicable to the technical field of robot control, and provides a robot control method, system and robot, including: when a motion command is received, the parameter value of the motion command is obtained and calculated, and the maximum torque value of all motion axes of the robot is obtained, compared The maximum torque value of each motion axis and the preset maximum torque value of each motion axis. If there is a motion axis whose maximum torque value is greater than the preset maximum torque value, the motion axis is used as the target motion axis; according to the target motion axis The preset maximum torque value, calculate the maximum acceleration value and maximum deceleration value of the target motion axis, plan the speed of the robot according to the maximum acceleration and maximum deceleration values ​​of the target motion axis, obtain the first speed planning result and output it, so as to The acceleration value of the robot is adjusted. The invention can detect and judge the motion state of the robot in real time, plan the speed of the robot, adjust the acceleration value, and reduce the loss of the robot.

Description

technical field [0001] The invention belongs to the technical field of robot control, and in particular relates to a robot control method, system and robot. Background technique [0002] In recent years, the application market of robots has become larger and larger, and the research on robots has become more and more in-depth. [0003] The existing algorithms for robot trajectory planning only consider the kinematics level, and the set kinematics parameters depend on the experience of technicians, and there is no uniform standard. [0004] However, if the kinematics parameter setting does not conform to the mechanical motion state of the robot, it will easily cause mechanical shock, and the reducer will be easily damaged after long-term operation, which will accelerate the wear and tear of the robot. Contents of the invention [0005] In view of this, the embodiment of the present invention provides a robot control method, system and robot to solve the kinematics paramete...
