Key Technologies of Telepresence in Time-Delayed Teleoperation System: Review and Analysis

This paper reviews some key technologies and progress in the field of telepresence of teleoperation, meaning human sense and control of remote telerobot. Telepresence is the symbol of teleoperation, phenomenon of which enables the human to feel present at a remote location however a time-delay exits always in the teleoperation system. There are three means to conquer the effect: bilateral control method, virtual model based control and virtual reality technology. By optimizing control strategy user will get a perfect force or visual telepresence. Finally, opinions are given as to the further development of the field.
