See full text

An actuation apparatus includes an electronics module (102), an actuator module (104) coupled to the electronics module and electrically communicating with the electronics module, and a motor (112) in the actuator module coupled to a drive member (106), the drive member moveable between a first position and a second position, wherein the movement of the drive member between the first and second positions is adjustable in response to a signal from the electronics module. In some embodiments, the electronics module is operable to adjust a speed of the drive member. The motor may be a brushless direct current motor. In other embodiments, the actuation apparatus (300) includes a processor and a memory, the adjustable drive member is engaged with an actuatable tool (200), the processor receives feedback from the drive member and the tool, and the processor is operable to create a signature in response to the movement of the drive member and compare the signature to a baseline.
