Abstract
The invention is a multiple degree-of-freedom test stand for unmanned air vehicles, and is particularly useful for small or micro unmanned air vehicles. The stand is gravity balanced using springs such that no weight of any part of the stand becomes a burden to the tested vehicle when it flies while constrained to the stand. A joint and a plurality of members are used to enable multiple degrees of freedom.
