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Traditional robotic work cell design and programming are considered inefficient and outdated in current industrial and market demands.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 virtual reality-based programming of a robotic work cell (VR-Rocell) is developed by solid modelling using commercial CAD software. The 3D models can be saved in a universal file format, either in STL, VRML, XML or OBJ. Following this, these models are integrated into the VR-Robotic Work Cell Layout (VR-RoWL) using a generic approach, in which the assembly models are saved in the VRML format. Virtual models can be transformed and saved in new files. The assembly models can be designed, modified and re-arranged accordingly. The models will be used to teach the robot path via the VR-based Robot Teaching system (VR-RoT). The robot commands and layout information can be loaded into the actual robotic work cell to execute the desired tasks. In addition, the VM models can be saved in different universal file formats. Therefore, the output models from one VM can be transferred or imported to another VM in the universal file format. Figure 7 shows the overview of the research.
