Research on Virtual Reality System of Gantry Dual-arm Welding Robot

In order to promote the development of ship automatic welding, this paper applies virtual technology to gantry welding robot used in ship welding. A method of creating kinematic digital twins in virtual reality is proposed. This method can restore the motion state of gantry welding robot in real time in the remote virtual client. The working condition of gantry welding robot can be known by observing the remote virtual client. With the help of solid works and 3DMAX, this method establishes the virtual model corresponding to the real equipment. Assemble the model in unity3d, establish a virtual environment corresponding to the real environment, and develop the remote client. This method obtains real-time motion data from the field industrial computer and transmits it to the remote client through the Internet. The remote client carries out data processing to achieve the effect of synchronous movement with the scene. Through the case analysis, this method can be used for the kinematic modeling of the digital twin of gantry welding robot, so as to monitor the welding movement and improve the working environment of the staff. And it has good visual effect and immersion. © 2023 CAD Solutions, LLC,.
