Abstract:
1. A system for moving and guiding a piece of apparatus and attached object (payload) into relationship with another piece of apparatus, comprising: a mobile apparatus that moves and does work on said external object (payload) by means of repeated bending, unbending motions in response to an external stimulus; a stationary apparatus that guides said mobile apparatus, exerts reaction forces on said mobile apparatus and supplies controlled power to said mobile apparatus; means of supplying and controlling power to said mobile apparatus. means for said mobile apparatus to remain in place with respect to said stationary apparatus with external power off and oppose external force on said mobile apparatus and said attached object (payload). means for said mobile apparatus and said attached object (payload) to be precisely positioned within said stationary object over relatively long stroke distances. said mobile apparatus wherein a first and second external component is each connected to an internal component by a bending structure and said first and second external components are each in constant contact with said stationary apparatus whereas said internal component is only in contact with said stationary apparatus when said bending structures are each sufficiently bent whereas said external object (payload) is connected to said second external components as to move with said second external component along said axis of travel without restricting the function of said mobile apparatus or any of its components therein. wherein directed and controlled power can be supplied to said stationary and mobile apparatus whereby said first external component of said mobile component is fixed and said second external component is freed and thereafter said internal component of said mobile apparatus is moved into contact with said stationary apparatus whereas each of said bending structures bends and free said second end component is pulled towards said fixed first end component and thereafter said free second component is fixed and said fixed first end component is freed and thereafter said internal component is freed whereas stored spring energy in each of said bending structures returns said internal structure to its unbent position whereas said free first end component moves away from said second end component and said mobile apparatus completes a single movement step with respect to said stationary apparatus along said system axis of travel in the second external component to first external component direction and
