Abstract

The invention discloses a teaching system and method of a mechanical arm. The teaching system comprises a visual motion capture module, a computer workstation, the mechanical arm and a teaching device, wherein the visual motion capture module can acquire a mark point in a scene or a space position of a rigid body in real time; control software comprises a data processing module, a mechanical arm control module, a mechanical arm calibration module and a visualization module; the teaching device comprises a control switch, a wireless communication module and a teaching mark point; and a user teaches the mechanical hand through the reaching device, and the tail end of the mechanical arm completes corresponding motion along a motion path of the teaching device. According to the teaching systemand the teaching method, mounting of the system is convenient, the teaching method and process are simple and quick, teaching efficiency and precision are greatly improved, and the teaching system has wide application prospects.

Description

technical field [0001] The invention mainly relates to a teaching system and method of a mechanical arm, which belongs to the field of robot technology and application. It can solve the problem that the teaching process is complicated when teaching the mechanical arm in the prior art. Background technique [0002] With the rapid development of industry, robotic arms are widely used in the field of industrial manufacturing. Through preset programming and assembly line work mode, the robotic arm can repeat fixed processing actions and procedures accurately and at high speed. The requirements are also getting higher and higher, not only requiring the industrial robotic arm to be able to complete repetitive tasks stably for a long time, but also to have the characteristics of intelligence, networking, openness, and man-machine friendliness. [0003] At present, the trajectory planning of industrial robots on the market is carried out through the teaching pendant. First, the tea...
