Abstract

The invention provides for a continuous/stepping rotary or linear actuator comprising a rotating output shaft 4, a drive gear 10, and at least one means for rotating 12 the drive gear 10 comprising material adapted to contract when activated 14, and electronic controls 30. This means for rotating 12 the drive gear 10 utilize force and motion generated by material adapted to contract 14 when activated. When the material adapted to contract 14 is activated, it moves the shuttle 24 and pawl 16 in a desired manner. Upon this movement, the pawl 16 grasps and turns drive gear 10 which drives the motion of the output shaft 4.
