For some circumstances, it would be extremely dangerous to use direct human labor and then robots are often required to complete those tasks in this kind of environments. Unfortunately, computer control and intelligence are not sufficiently developed to permit the robots to fulfill these advanced technical tasks only by their own initiative. Tele-operation robot may be a good way for this problem. Robots will fulfill the given task at the real environment to avoid the possible harm to people and engineers will give out the proper instructions to robot in tele-operation mode. A type of manipulation robot will be introduced and key technologies will also be explained. It synthetically adopts wireless network video technology, photoelectric sensor technology and wireless Bluetooth technology. By this method, the operator can obtain even more information of the working environment, and the robot will also complete the dangerous task more effectively.
