Abstract
Disclosed is a high degree of freedom control apparatus that includes a base attached to a strain gauge assembly movable in three orthogonal directions to provide signals indicative of a position of the strain gauge assembly relative to the base. An actuator assembly is supported on the base and movable by an operator's arm, hand, digit, or wrist relative to the base structure. The actuator assembly provides signals indicative of the position of the operator's arm, hand, digit or wrist in at least seven degrees of freedom relative to the base structure. The actuator assembly includes a wrist angle stage and a digit angle stage. The strain gauge assembly includes a spring plate and a load cell that is configured to provide a signal indicative of deflection of the load cell relative to the base.
