Abstract
Future high-dexterity robots promise enormous benefits to many areas of human endeavor performing operations difficult or hazardous for humans such as extra vehicular repairs. However, operating complicated tools and performing intricate repairs requires manipulators of great precision and excellent coordination. Human hands are very complex instruments with capacity for reception of and reaction to tactile stimuli for guidance in their functions. Integration of tactile sensing suites into robotic platforms (presently sensor impoverished) poses major technological challenges. The IFOS team, including well-known robotic experts from Stanford and JPL, proposes smart robotic skin including embedded Fiber Bragg Grating (FBG) sensors, custom-engineered composite skin materials, data interpretation and on-board decision-making. Phase I demonstrated feasibility. Phase II will deliver an FBG sensor-assisted manipulator prototype (hand and arm) based on high-resolution loading and artificial taction. Immune to electromagnetic interference, FBG sensors are easily integrated into robotic structures, highly sensitive and multiplexable allowing many sensors on a single fiber. This will enable robotic manipulators with high-fidelity force control for precise object grasping, positioning and safe operation with astronauts. They will facilitate maximum functionality, minimum weight and size of extra-vehicular robots to extend the life and reduce costs of new generations of space systems.
