Abstract

In the field of robot flexible welding

a multi-robot master-slave coordinated motion control system is designed and implemented. The system adopts a centralized control architecture and a cyclic synchronous position mode.Based on a general multi-robot master-slave coordinated motion control algorithm

the coordinated motion target matrix of slave robot is calculated. Furthermore

the master-slave coordinated motion control process and the corresponding programming instruction set are designed in robot controller.Finally

a multi-robot flexible welding system is set up with four Kaierda KR1440 robots. Through the test of robot program teaching and playback for typical master-slave coordinated welding tasks

the multi-robot master-slave state online switch function is realized and the effectiveness of the control system is verified. This work provides a technical basis for further improving the flexibility of the robot welding system.
