ABSTRACT:
A screwdriver is disclosed comprising a base, a carriage moveably coupled to the base, an actuator operable to move the carriage relative to the base, and a slider comprising an attached screw bit, wherein the slider is coupled to the base through the carriage and the slider is moveably coupled to the carriage such that the slider and attached screw bit move together relative to the carriage. The screwdriver further comprises a position detector operable to detect a position of the slider relative to the carriage. In one embodiment, the carriage is moved relative to the base to move the screw towards the work surface. After the screw contacts the work surface, the carriage is moved further relative to the base causing the slider to move relative to the carriage, and the movement of the slider relative to the carriage is detected using the position detector.
