ROTABLE DRIVER, METHOD FOR TRANSFERING A DRIVING FORCE TO A REVERSIBLE EXPANDABLE STRUCTURE, EXPANSIBLE REVERSIBLE STRUCTURE, AND METHOD FOR TRANSFERING A FORCE TO A BODY.
ROTABLE DRIVER, METHOD FOR TRANSFERING A DRIVING FORCE TO A REVERSIBLE EXPANDABLE STRUCTURE, EXPANSIBLE REVERSIBLE STRUCTURE, AND METHOD FOR TRANSFERING A FORCE TO A BODY.
An actuator is provided for reconfiguring a reversibly expandable structure, also referred to as a deployable structure. The deployable structure includes an enclosed mechanical linkage capable of transformation between expanded and collapsed configurations while maintaining its shape. An actuator coupled to the deployable structure provides a load, force, or torque for actuating a transformation. The actuated deployable structure transfers the actuation force to an external body substances, or element in contact with the deployable structure. The force can be directed inwardly or outwardly depending upon direction of the transformation (i.e., expanding or contracting). The force provided by the deployable structure can be used to perform work by its application over at least a portion of the distance traveled by a perimeter of the deployable structure during its transformation. In some embodiments, the actuatable deployable structure is lockable structure supporting a static load.
