VR system control-based industrial robot teaching system and teaching method thereof

Abstract

The invention relates to a VR system control-based industrial robot teaching system and a teaching method thereof. The system comprises a visual system, a VR system and a robot system. The visual system is used for acquiring, analyzing and processing the overall structure of an industrial robot, parameterizing the image information, and transmitting the information to the VR system through the Ethernet in the TCP / IP mode. The VR system is used for approximately constructing the structural model of an actual robot in a virtual scene according to the image information obtained by the visual system, realizing the simulation motion and transmitting the model in the form of data to the robot system through the EtherCAT, Modbus communication mode. The robot system is used for controlling the robot to generate motions according to the change position information transmitted by the VR system. According to the invention, firstly, the VR technology is combined with the industrial robot technology, and the robot is controlled to complete teaching tasks. Therefore, the teaching precision of the robot can be improved, and the labor intensity of an operator can be relieved. The working enthusiasm of the operator can be improved.

Description

technical field [0001] The invention relates to the technical field of robot teaching, in particular to an industrial robot teaching system and a teaching method based on VR system control. Background technique [0002] Virtual Reality, sometimes called Aura, is a computer system that can create and experience virtual worlds. In 1995, a VRML language based on SGI's Open Iventor file format was withdrawn, which not only realized 3D geometric modeling and physical modeling, but also supported the interaction and hyperlinks between users and scenes, and at the same time accelerated the development of 3D graphics on the network. on the transfer speed. [0003] With the development of science and technology, industrial robots, as a major branch of the robotics field, began to appear more and more on the production lines of factories, such as robot painting, robot palletizing, robot welding, etc. Before the robot completes the prescribed actions, the workers need to program and ...

Problems solved by technology

However, this method mainly relies on the experience of the operator. The operator visually determines the movement position of the robot. The accuracy is low and it is not suitable for tasks with high requirements such as welding.

In addition, this method consumes a lot of physical strength for the operator and is prone to fatigue, and it will affect the personal safety of the operator in the dangerous environment where the robot works
