A MDL-Based Control Method for Tele-robotic Systems over Internet

A MDL-based control method for tele-robotic systems over internet is presented in this paper. Internet-based tele-robotic systems are characterized by the fact that the operator and the remote robotic system are connected by Internet. Since limited bandwidth, random time delay and other transmission problems deteriorate performance of tele-robotic systems severely, control strategies which can be used to settle transmission problems are expected. The obvious characteristic of the new method introduced in this paper is that control commands have a linguistic flavor, data transferred between operator and remote robot can be reduced accordingly. The framework presented in this paper has the potential of reducing operator's working pressure and enhancing the performance of the system. Furthermore, the existing motion description language modal is expanded to deal with the packet loss and disorder problem. The main contribution of this paper is the development of a novel framework for tele-robotics and its implementation in a real tele-manipulator system.
