Abstract

Recently, research using VR (Virtual Reality) technology has been ongoing in developing remote control systems used for working in dangerous or severe environments. However, some problems concerning recognition, operation and so on remain. In this study, the authors propose a practical remote control method which solves some of these problems. First, the system has more than two stereoscopic cameras which are used to see the robot's hand, objects and so on. The reason for this is that the shadows behind the objects or other objects in only one field of vision decrease the amount of sufficient information needed. The method of showing these views to the operator is by switching the views on one display. Secondly, operation using the view coordinate system (the view oriented operation method) is adopted to solve the problem of operation confusion. With this method, an device coordinate system is made to coincide with a view coordinate system, this helps the operator to recognize the operation direction according to the operator's own will. Thirdly, a work point tracking method is adopted not to lose sight of the object when switching views. In experimenting and testing, several kinds of tasks were performed to confirm the effectiveness of these methods. Using the above methods, these tasks could be performed faster than before, and moreover, the operator could operate the robot more dexterously. In conclusion, these methods can create a more efficient remote control system.
