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.

Abstract: A control actuator apparatus is presented having an actuator assembly providing three linear motion degrees of freedom relative to a base and three rotational degrees of freedom, and one or more additional actuators providing at least one additional degree of freedom, including a base structure, an XYZ stage, and an upper actuation assembly with a wrist angle stage, a forearm angle stage, and a digit angle stage providing relative positioning signals or values to facilitate machine control capabilities with a high number of degrees of freedom (high DoF).
