Bottom Line: A case study is conducted in the Robotics Laboratory to assemble an electronics casing and it is found that the output models are compatible with commercial software without loss of information.Furthermore, the generated KUKA commands are workable when loaded into a commercial simulator.The operation of the actual robotic work cell shows that the errors may be due to the dynamics of the KUKA robot rather than the accuracy of the generated programme.

ABSTRACT
Traditional robotic work cell design and programming are considered inefficient and outdated in current industrial and market demands. In this research, virtual reality (VR) technology is used to improve human-robot interface, whereby complicated commands or programming knowledge is not required. The proposed solution, known as VR-based Programming of a Robotic Work Cell (VR-Rocell), consists of two sub-programmes, which are VR-Robotic Work Cell Layout (VR-RoWL) and VR-based Robot Teaching System (VR-RoT). VR-RoWL is developed to assign the layout design for an industrial robotic work cell, whereby VR-RoT is developed to overcome safety issues and lack of trained personnel in robot programming. Simple and user-friendly interfaces are designed for inexperienced users to generate robot commands without damaging the robot or interrupting the production line. The user is able to attempt numerous times to attain an optimum solution. A case study is conducted in the Robotics Laboratory to assemble an electronics casing and it is found that the output models are compatible with commercial software without loss of information. Furthermore, the generated KUKA commands are workable when loaded into a commercial simulator. The operation of the actual robotic work cell shows that the errors may be due to the dynamics of the KUKA robot rather than the accuracy of the generated programme. Therefore, it is concluded that the virtual reality based solution approach can be implemented in an industrial robotic work cell.

Mentions: The original assembly model is then imported into the VR-RoWL. The models are free to move within the fixed zone (grid). In general, the robots should be placed in parallel and facing towards the positive y-axis direction. The assembly zone is located between the robots and within the workspace of both robots. This layout design can be implemented for various assembly processes involving two robots, whereby the materials supply is located in front of the robots. Therefore, the new layout can be obtained by moving the related machines/robots in the virtual layout. The new layout can be saved in the VRML format, which can be shared between various Internet browsers. The proposed robotic work cell created by the VR-RoWL and the actual laboratory setup are shown in Figure 9.
