Space Robotics
Abstract:
This report surveys the possible applications and technical feasibility of robots in space. The future space program in the time frame of 1980-2000 is first assessed, including space exploration, global information services and space utilization. The critical technologies needed to support the projected space program are then considered, including the need for general purpose, remote intelligence and manipulation. Teleoperators are discussed as a possible means of meeting this requirement and are found not to be satisfactory due to communication time delays and bandwidth limitations, and human costs and performance limits. Autonomous space robots are proposed as a solution and several detailed scenarios for their use are presented. The technical feasibility of space robotics is evaluated by examining the requirements, state of the art, and research needed for each of the subsystems of a space robot. These include manipulators, sensors, navigation, guidance, propulsion, surface locomotion, computing and control, communications, electrical power, and spacecraft structure. Finally, a research program is outlined for the development of autonomous space robots.
