66 -- SPACE STATION TRAINING FACILITY HAND CONTROLLER REQUIREMENTS SOL 9BE33G27511P DUE 013095 POC WENDY BOUDREAUX, Tel:713-483-5338 Contracting Officer:LISA REA, Tel:713-483-8395 The Automation, Robotics and Simulations Division (ARSD) has an agreement with the Mission Operations Directorate (MOD) to integrate the Remote Manipulator System Simulator to the Space Station Training Facility. The Remote Manipulator System Simulator utilizes Space Shuttle Orbiter flight type rotational and translational hand controllers. These hand controllers shall mimic the actual hand controllers while utilizing transducers that are compatible with existing electronic hardware. The hand controllers will be integrated, with an ARSD built electronic interface, to a Silicon Graphics Inc. Reality Engine utilizing the Trick dynamic modeler (software modeling package developed by ARSD). Therefore, the hand controllers shall utilize resistive potentiometers of a range of 5K ohms and normally open switches, to be electrically compatible with this interface. Furthermore, the hand controllers must fit into an existing hand controller and a volume of 3.5''X3.5''X4.75'' for the translational hand controller. The mounting interface for each enclosure is a 3.91'' in diameter hole and four tapped #6-32 holes on a 3.4'' square. The hand controller subsystem, in conjunction with the Silicon Graphics Inc., will be used as a development and training tool for the Space Station Remote Manipulator System (SSRMS). Training requires tools that ensure positive feedback to ensure familiarity with the SSRMS and to reduce the learning curve. Therefore the input devices, namely the hand controllers, must be accurate to the actual hardware while meeting the interface requirements listed above. The grips shall be of the same shape as existing hardware. Geometry and force specifications shall be compatible with the Space Shuttle RMS hand controllers.
