For the past three decades, the author and his colleagues in the MIT Man-Machine Systems Laboratory have been carrying out experimental research in the area of teleoperation, telerobotics, and supervisory control - a new form of technology that allows humans to work through machines in hazardous environments and control complex systems such as aircraft and nuclear power plants. This timely reference brings together a variety of theories and technologies that have emerged in a number of fields of application, describing common themes, presenting experiments and hardware embodiments as examples, and discussing the advantages and the drawbacks of this new form of human-machine interaction. There are many places - such as outer space, the oceans, and nuclear, biologically, and chemically toxic environments - that are; inaccessible or hazardous to humans but in which work needs to be done. Telerobotics - remote supervision by human operators of robotic or semi-automatic devices - is a way to enter these difficult environments. Yet it raises a host of problems, such as the retrieval of sensory information for the human operator and how to control the remote devices with sufficient dexterity. In its complete coverage of the theoretical and technological aspects of telerobotics and human-computer cooperation in the control of complex systems, this book moves beyond the simplistic notion of humans versus automation to provide the necessary background for exploring a new and informed cooperative relationship, between humans and machines.
