The proposed innovations conform precisely to the technology needs described in Subtopic T5.02, Robotics and Virtual Digital Human Technologies. ?Two potential areas for research are the ever-evolving robotics and 3-D simulation technologies providing operational robustness and intelligence.? Our proposal explicitly addresses two of the ?specific technology requirements?: the application of haptics for improved operator awareness of and reaction to robotic activity; and the introduction of stereographic display systems for optimized operator visual situational awareness. We extend our proposal?s relevance by ?offering innovation in the form of 3-D visualization and simulation capabilities of robotic systems with relation to the 3-D virtual-digital-human-in-the-loop concept.? Our VDH technology can place realistic virtual humans working collaboratively with virtual Robonauts in synthetic environments that emulate Space Station or Space Shuttle. Finally, we propose to address the application targets of ?flight and ground operations development, analyses, training and support? by incorporating gravitational force as a variable in the simulation environment, offering the design of highly realistic tests that ?improve the ability of humans and computers to seamlessly control robotic systems?. The Phase I investigation could result in opportunities for design enhancement of the robotic devices themselves.
