Abstract

The invention discloses a method and device for determining the trajectory accuracy of a robot, and an industrial robot. Wherein, the method includes: constructing a flexible robot model and a rigid robot model, wherein the flexible robot model corresponds to the flexible value of each joint of the target robot, and the rigid robot model corresponds to the rigidity parameters of each part of the target robot; using the flexible robot model and The rigid robot model controls the target robot to run along the pre-determined target trajectory to obtain two running lines; calculate the deviation section between the two running lines to determine the trajectory accuracy of the target robot. The invention solves the technical problem in the related art that errors are prone to occur in the calculation of the trajectory accuracy of the robot during the dynamic operation process.

Description

technical field [0001] The invention relates to the technical field of robot control, in particular to a method and device for determining the trajectory accuracy of a robot, and an industrial robot. Background technique [0002] In the related art, the transmission structure of most industrial robots is the transmission structure of motor, gear (or synchronous belt) and speed reducer. During the process, the acceleration and deceleration, the weight of the connecting rod and the change of the load will deform the joints of the robot, which will affect the accuracy of the robot, especially the trajectory accuracy. At present, when calculating the trajectory accuracy of the robot, most of them are obtained based on the preset kinematics model. This method is effective for calculating the positioning accuracy of the robot at a specified position, but it is not suitable for the robot during dynamic operation. The trajectory accuracy error caused by joint elastic deformation ca...
