Telerobotics and orbital laboratories: an end-to-end analysis and demonstration.
A preliminary analysis of the United States Laboratory (USL) module of the International Space Station has been completed. A major conclusion was that one of the most limited resources within the USL will be crew time. A laboratory robot would alleviate these constraints, improve safety, and reduce operational costs. A laboratory experiment manipulator system (LEMS) is proposed, made up of an on-board mobile manipulator and a computer-assisted operator control station. The on-board manipulator concept was tested with an Intelledex 660 industrial robot. Operator joystick command capability and delayed video feedback were added to simulate a Space Station Teleoperation system. The implementation of a unique predictive display was chosen for further evaluation because of its promise as a partial solution to the classical problem of robot remote control in the presence of time delay. The incorporation of various correction factors to calibrate the robot predictor model, including geometric distortion and spherical aberration caused by the video optics, is described.
