摘要：The Operational System for Inspection, Research, and Instrument Support (OSIRIS) is a remotely operated free-flying camera robot. Designed to fly in air, OSIRIS has full six axis control and can serve as a test platform for several areas of research including attitude control, path planning, inspection tasks, and human -robot interaction. Currently, fixed cameras are used to help astronauts inspect the exterior of the ISS before, d uring, and after EVAs. However, fixed cameras cannot provide the most convenient views, and cannot view a single area from all angles. By using a free-flying camera robot, inspection and verification of the workspace could be done by focusing in on the desired areas in great detail. Similar vehicles designed in the past use ducted fans and compressed air for propulsion. OSIRIS implements an alternative propulsion system, the centrifugal pump -jet propulsor. Upon vehicle integration, the system was tested in a micro-gravity environment on board NASA's KC-135 Weightless Wonder V where it had uninhibited motion. These tests were used to measure the functionality and effectiveness of the propulsion system and to determine a preliminary characterization of the vehicle dynamics. Analysis demonstrated that the propulsion system can effectively run a space simulator vehicle in air in a microgravity environment.
