teleoperationTeleoperation, also called telerobotics, is the technical term for the remote control of a robot called a telechir .In a telerobotic system, a human operator controls the movements of atelechir from some distance away. Signals are sent to the telechir tocontrol it; other signals come back, telling the operator that thetelechir has followed the instructions. These control and returnsignals are called telemetry . Some teleoperated robots have a limited range of functions. Agood example is a space probe, such as Voyager, hurtling past someremote planet. Earthbound scientists sent commands to Voyager based onthe telemetry received from it, aiming its cameras and resolving minorproblems. In a more sophisticated form of teleoperation known as telepresence , the human operator has a sense of being on location, so that the experience resembles virtual reality (VR). For example, a telechir can be equipped with sensors that detect sensations of vision and sound, and in some cases pressure and texture. Thesesensations can then be reproduced at the operator location by means of specialized transducer s.
