Detection method and device for robot manipulator

Abstract

The invention discloses a method and device for detecting a mechanical arm of a robot. The device for detecting the mechanical arm of the robot comprises a detection work platform, a plurality of first sensors and a controller, wherein the signal detection ends of the multiple first sensors are distributed on a platform face of the detection work platform, and the first sensors are used for detecting the distance Ei between an extension point Pi of a sphere and the first sensors Si; the controller is connected with the signal output ends of the first sensors, and is used for calculating the sphere center position of the sphere in a preset coordinate system according to the distance Ei to the distance En. The preset coordinate system is a rectangular coordinate system with the center of the platform face as an original point. By means of the method and device, the problem that the accuracy for detecting a mechanical arm of a robot in the prior art is relatively low is solved, and the effects of improving the detection accuracy and reducing the device cost are further achieved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a detection method and device for a robotic arm of a robot. Background technique [0002] At present, the robot industry in many countries represented by Japan, the United States, Germany, France, and South Korea is becoming more and more mature and perfect, and the industrial robots produced have become a standard equipment and are widely used around the world.
