Abstract

The invention is applicable to the technical field of robot control and provides a robot control method, a robot control system and a robot. The robot control method comprises the steps that when movement instruction is received, the parameter value of the movement instruction is acquired, and calculation is conducted; the maximum torque value of all movement axes of the robot is acquired, the maximum torque value of each movement axis is compared with the preset maximum torque valve of each movement axis, and if a movement axis whose maximum torque value is larger than the preset maximum torque value, the movement axis is adopted as a target movement axis; and according to the preset maximum torque value of the target movement axis, the maximum accelerated speed value and the maximum decelerated speed value of the target movement axis are calculated, speed planning is conducted on the robot according to the maximum accelerated speed value and the maximum decelerated speed value of thetarget movement axis, and a first speed planning result is acquired and output so that the accelerated speed value of the robot can be adjusted. By means of the robot control method, the movement state of the robot can be detected and judged in real time, speed planning and adjustment of the accelerated speed value are conducted on the robot, and loss of the robot is lowered.

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...
