Abstract

The embodiment of the invention discloses a control method and a control device for a Cartesian coordinate robot. One specific implementation mode of the method comprises the following steps: obtaining initial position information and target position information of the robot in response to a received operating control instruction; determining initial reference position information and target reference position information of the robot in an established reference coordinate system; and executing the following control steps: obtaining current actual position information and current theoretical position information of the robot to determine the current reference position information of the robot, and determine whether the current reference position information is the target reference position information in the first coordinate axis direction; and in response to determination that the current reference position information is not the target reference position information, by taking the current reference position information as the initial reference position information, continuously executing a control step. The implementation mode can implement that during operation of the robot, an error produced in the first coordinate axis direction can be dynamically compensated, so that the operation efficiency is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of robot control technology, in particular to a control method and a control device for a Cartesian robot. Background technique [0002] Cartesian coordinate robot, as an automatic robot with low cost and simple system structure, can be used in common industrial production fields such as dispensing, spraying, palletizing, sorting, packaging, welding, handling, loading and unloading, assembly, and printing. This can replace labor, improve production efficiency, and help stabilize product quality. [0003] A Cartesian robot usually consists of five parts: a horizontal-axis main arm, a vertical-axis main arm, a third-dimensional axis main arm, a rotating arm, and a gripper. The main arm of the horizontal axis, the main arm of the vertical axis and the main arm of the third dimension axis can respectively drive the mechanical claws to move linearly along the ho...
