Visual servo in laser remanufacturing robot

Intelligent laser remanufacturing robot system has meant a revolution since it is convenient, flexible, high automatic and precise. It is based on industrial robot, vision, high-tech surface techniques and rapid prototyping technology. It has been developed quickly in recent years. Compared to the previous laser remanufacturing system, it has a high degree of automation due to the vision sensors. In this system, morphology information of parts is acquired by cameras, transmitted to the PC via USB. Through image processing and stereo vision algorithms, 3D shape is reconstructed. The defect location is identified and repair parameters are given. Via Ethernet the robot controller is communicated with PC which guides the processing path and speed and monitors the repair process in real-time, feeding back at any time to modify the parameters until fully repaired. This article describes the components and tools, both hardware and software. After testing, the vision servo system performs well.
