1. An actuator system comprising:
a tooth actuator comprising teeth on a surface;
a tensioner to apply a tension force to the tooth actuator;
a movable and controllable hold pawl to hold the tooth actuator stationary, through disengage-able contact with at least one of the teeth, with respect to a direction of the tension force while allowing the tooth actuator to move freely in a direction opposite the direction of the tension force;
a movable and controllable advancement pawl having at least two degrees of freedom that enable engagement of the moveable and controllable advancement pawl with a first one of the teeth on the tooth actuator and displacement of the tooth actuator a distance in the direction opposite of the direction of the tension force; and
a contracting linear actuator, attached to the movable and controllable advancement pawl, a pulling force of which (i) causes the engagement via a rotational movement of the movable and controllable advancement pawl and (ii) after the rotational movement ceases, causes the displacement via linear movement of the movable and controllable advancement pawl.
