Abstract: 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.

Abstract: Man-machine cooperative teleoperation and multi-control modes transfer in due time are the key problems that the telerobot system must deal with. That is the intelligence of the operator and the robot in the system should be distributed appropriately according to the current task state. The current task state of the telerobot system should be evaluated to solve these problems. So the telerobot control system is built with current task state evaluation after analyzing system control modes. For the control modes transfer in due time, its Petri Net (PN) model is built and it is simulated with the Stateflow module of Matlab. Simulation results show the validity and rationality of the model.

Abstract: This paper proposes replacement of a tele-controller system to base on DTMF in spite of tele-system web. It is found that telesystem with Dual Tone Multiple Frequency has a large capability in send-receiving of data in hardware and software. It dos not need to install of a PC for receiving and processing of data as tone modulated form from slave side. In other hand, its adaptive ability with different phone lines and no any need to spare devices of network such as net card or modem and no contribution from local networks of internet and finally different master interfacing capabilities with a single slave are examples of the advantages of the system. Also, synchronous using of internet lines like ADSL in other applications such as video image sending (due to system development) is one of the other advantages of it. This paper describes several interface system and control system with experimentally tests according to the ISO9283 standard and Delay-Time in this the Tele-Robot.
