dc.description.abstractWheel performance has been one of the limiting factors in interplanetary rover mis-
dc.description.abstractsions. Because the rigors of space restrict use of conventional tire materials, rover
dc.description.abstractwheels suffer from lack of traction, high risk of snagging, and little or no compliance,
dc.description.abstractwhich limits the rover's ability to explore and traverse discontinuous terrain. What
dc.description.abstractis worse is that these limitations go unresolved by the current lack of testing. The
dc.description.abstractconcept that wheel utilization and design are enhanced by testing is not new. The
dc.description.abstractApollo program enjoyed substantial testing of the Lunar Rover Vehicle's wheel but
dc.description.abstractat a tremendous cost in time and money, which is probably the reason for its current
dc.description.abstractlow priority. Single wheel testing is a solution to this problem because it can cheaply
dc.description.abstractprovide data for a full rover assembly's performance. This paper details these prob-
dc.description.abstractlems and provides solutions to several road blocks of using single wheel testing as
dc.description.abstracta substitute for full rover testing. The Suspension and Wheel Experimentation and
dc.description.abstractEvaluation Testbed (S.W.E.E.T), which is specifically designed to test single wheels
dc.description.abstractin situations previously neglected, will enable engineers to iteratively improve wheel
dc.description.abstractdesign and to develop more accurate and encompassing mission contingency strategies
dc.description.abstractwithout the cost and time of full rover testing.
