                                    9.1 Outline of a basic telepresence system

                                believe  in  and  interact  with  the  computer’s  synthesized  environ-
                                ment. In telepresence the environment is real but remote. So, in-
                                stead  of  a  computer  generating  a  synthetic  environment,  the
                                sensors placed on the remote robot feed all spatial and environ-
                                mental information to the user, in such a way that the user actually
                                feels that he or she is there.
                                On this human side, as stated before, the same VR equipment is
                                used to provide sufficient information from the remote sensors to

                                fool our senses into believing that the environment is real and pre-
                                sent. Different levels of presence are achieved depending upon
                                the fidelity of the interfacing devices. A humanoid robot that could
                                accurately  follow  human  movement,  gestures,  locomotion,  and
                                balance while providing visual, thermal, tactile, and force reflec-
                                tion over its entire exoskeleton to the human operator would be a
                                perfect  golem.  The  illusion  created  is  that  the  operator  has
                                merged or is contained within the robot structure.
                                Current telepresence systems fall quite short of this goal. In many
                                cases the remote robot is a vehicle, like the one we shall build.
                                The best telepresence existence available using these rudimen-
                                tary T-bots allows one to believe he or she is actually driving the
                                vehicle from inside.

                                T-bots can be built to explore and operate in harsh or hazardous
                                environments. A partial list of remote environments include arctic
                                waters, ocean floors, forest fires, active volcanoes, nuclear reac-
                                tors, the Moon, Mars, or anything in between.
