Abstract

NASA has committed to the design and implementation of a Space Station Flight Telerobotic Servicer (FTS) to assist the astronauts in assembly, maintenance, servicing, and inspection tasks on the Space Station and the Space Shuttle. One of the requirements of the FTS is safety. Safety is not solely dependent on the visible hardware components such as manipulators and hydraulic systems. It is also dependent on the underlying software which controls every action of these hardware components. An acceptable level of safety can only be reached by analyzing and implementing safety issues through the conceptualization, design, construction, and operation phases of the FTS. This article discusses three issues that are critical to the FTS safety. These include software design philosophy, software operating models, and a safety subsystem.
