Recommendation. The National Aeronautics and Space Admin~s~abon should
continue to explore advanced robotic technologies that have the potential to increase
the efficiency of human-robot teams onboard the International Space Station. This
should include space flight testing of the Ranger vehicle as a proof of concept.
Recommendation. The National Aeronautics and Space Adm~shation should
assess the potential improvements In extravehicular activities from the introduction
of new robotic technology into human-robot systems. This assessment should
include a comparison of the cost for development and ~mplementabon and the
potential cost savings and risk reduction associated with the use of these systems.
EXTRAVEHICULAR ACTIVIlrY AND ROBOTICS
The current ISS robotic teleoperators require a significant ~nveshnent of crew
time for extensive hanung in operations that require great skin and attention to
detail. The current ISS robotics are based on the successful history of the Space
Shuttle remote manipulator system and do not represent a significant advancement
In technology.
The lSS will provide a unique opportunity to establish synergistic activities by
suited crew members and robotic systems. Highly mobile, reduced size and weight
space suits and autonomous robotic systems with a high degree of dextenty are
cnbcal areas of research and development for which the I:SS could serve as an
engineering test bed. For example, a small HE space suit, which is being
considered for use on He ISS after Assembly Complete, could be used as a test bed
for advanced technologies (i.e., automatic thermal control, advanced LSS,
performance and physiological measures, actively controlled materials and
structures, and biological technologies). In addition, two new prototype space suits
have been delivered to NASA that could to be evaluated wad robotic assistants
(Hatfield et al. 1999).
NASA intends the ISS to be "an Important test bed for solar system exploration"
(Nicogossian, 1999). Therefore, the development of robotic technologies for servicing
in space will be important for more than the ISS. Future HEDS (Human Exploration
and Development of Space) nubatives, and solar system exploration missions, wiD
also benefit from remotely operated robotic systems that can perform external
inspections, servicing, maintenance, and repair. For unmanned missions, robotic

servicing will be the only option.
Recommendation. The National Aeronautics and Space Adm~s~ation should use
the International Space Station (ISS) as a technology test bed for advanced
extravehicular activity (EVA) systems, including robotic systems to support long-
term ISS operations and future space missions. Rather than introducing only
incremental changes, revolutionary approaches should be pursued to developing
new materials, achieving greater mobility, and incorporating new technologies for
both EVA suits and robotics systems In support of future exploration initiatives.
