Paper Abstract

Although significant technical challenges still remain, perhaps the pacing item in the development of space telerobotics is in the defmition of a programmatic need that is, in demonstrafing capabilities that can lead to a body of committed and eager users in the operational community. In the parallel area of extra-vehicular activity (EVA), such capabilities are routinely demonstrated through the use of neutral buoyancy simulation. This paper addresses the underlying rationale behind the use of neutral buoyancy simulation in telerobotics research, including details of the well-modeled dynamic environment; the existence of a sizable data base on EVA operations in neutral buoyancy with correlation to flight experience; and routine access to a number of high-fidelity mockups of past and planned operational spacecraft. Details are presented on the compromises necessary for the design and construction of neutral buoyancy telerobotics systems, and data will be summarized from a number of past simulations, including correlation of neutral buoyancy structural assembly with EVA flight data, and some preliminary tests of telerobotic servicing of Hubble Space Telescope. Finally, details will be given of a future telerobotic vehicle under detailed design at present, aimed at providing low-cost space flight data on telerobotics and extending the EVA paradigm of neutral buoyancy simulation based on known correlation factors to flight data.
