207 Deformable structural arrangement US541195 1995-10-16 US5727391A 1998-03-17 Vincent Hayward; Danny Grant
An actuator develops a displacement from a force; the actuator employs active tension elements which comprise a fiber or fibers which shorten under activation, for example, shape memory alloy fibers; the fiber or fibers are entrained between opposed, spaced apart support members, typically a stack of spaced apart disks; the entrained fiber or fibers define a cage of crossing lengths of fiber in symmetrical array, typically a helicoidal array. Activation of the fibers shortens the fiber lengths producing a relative displacement of the support members which can be translated to a component which is to be displaced, and to which the actuator is operably connected, in another embodiment the active tension elements stretch under stress so that instead of an actuator there is formed a shock absorber which eliminates displacement with a force.
208 Flexible robot arm US211581 1994-04-08 US5469756A 1995-11-28 Wendelin Feiten

An apparatus having various basic elements which are flat, arranged one on top of the other so as to tilt and are connected to one another by means of joints is provided. Here, the individual basic elements are arranged along a stacking axis. Between the individual basic elements, adjusting members, e.g. air chambers are provided which make it possible to set a precise angle between the respective basic elements. Control logic and a control bus with an electric power supply ensure in each adjusting member that the predetermined position is maintained.
209 Flexible positioning appendage US909960 1992-07-07 US5297443A 1994-03-29 John D. Wentz
A flexible appendage for use as a robot arm, controllable medical instrument, or simply a toy, has flexibly coupled segments defining an open lumen, and flanges protruding laterally of the axis. The flanges have passages for control lines spaced laterally from the axis. Each control line is fixed to a segment and can be pulled through the other segments from the proximal end. The control lines shorten a lateral side of the appendage to controllably bend it. Resilient couplings between the segments, leave open the lumen for passage of conduits or tools. The couplings can be helical springs wound with turns which abut at rest, such that the couplings elongate on the outside of a bend but do not compress on the inside, thereby maintaining the overall length of the appendage. The control lines are distributed around the axis, and can be arranged in ranks for controlling groups of the segments at different distances from the proximal end. The springs coupling proximal segments are more rigid than for distal segments, and the segments can be smaller and/or longitudinally shorter approaching the distal end.
210 In bundle foreign object search and retrieval apparatus US661825 1991-02-27 US5286154A 1994-02-15 Stephen C. Jens; Michael W. Osborne; Paul F. Viola; Christos Athanassiu; Robert A. S. Lee
An apparatus (10) for the location and removal of foreign objects from a difficult to access geometry utilizes a flexible lance (12) formed of individual hose bar segments (14) strung on cables (16) to give a structure that is flexible along its length and fairly rigid in a direction transverse to its length. Extending from working channels (18) of nozzle block (20) of the lance (12) are a pair of multi-prong retrievers (22). A miniaturized Videoprobe camera (24) is provided in the nozzle block (20) between the two retrievers (22). The retrievers are each connected to an actuating cable (26), which extends through the flexible lance (12) to a manual control (28). The camera (24) is connected by a cable (30) to suitable video processing circuits for generation of images on a video display (32). The cable (30) also houses a fiber optic bundle which conveys light to the area being serviced by the lance (12). The flexible lance (12 ) extends through a transporter (34), which positions the nozzle block end of the lance (12) opposite a portion of a steam generator or other difficult to access geometry. The transporter (34) moves along a transport rail (36) to move the nozzle block end of the lance (12) into position. The lance (12) is then advanced through the transporter (34) to move the nozzle block end into the difficult to access geometry and retracted to withdraw the nozzle block end from the difficult to access geometry.
211 Flexible robotic arm US754828 1991-09-04 US5142932A 1992-09-01 Israel A. Moya; Philip A. Studer
A plurality of identical modules are serially connected together with each module including a base plate and a top plate interconnected by a universal joint assembly so that the top plate is adapted to pivotally nutate around the base plate to describe a cone in space. An array of twenty-four electromagnets, sequentially energized in sets of three, are arranged in a ring around the periphery of the base plate. Selective energization of the eight sets of electromagnets causes the rim of the top plate to be magnetically attracted to the energized electromagnets. The tilt of the top pivot plate is detected and controlled over a range of 360.degree., thus permitting a series string of modules to assume any desired elongated configuration.

Each unit includes at least three expandable and contractable operating members in the form of link mechanisms or double thread type expandable and contractable rods, and actuating devices for equally or unequally expanding and contracting the operating members so as to increase or decrease distances between the connecting members while maintaining them in parallel or inclined with respect to each other.
215 Grappling device US938947 1986-12-08 US4815782A 1989-03-28 Preston S. Craig; Jeffrey A. Fisher
A grappling device comprises an arm formed from a closed ended, inflatable tube (5) having a plurality of generally parallel, longitudinally spaced bands (15) disposed therearound for limiting the radial distention of the arm when inflated. A longitudinally inelastic, laterally flexible band (20) disposed on a surface of the arm causes the arm, when inflated, to wrap around an object to be gripped. The extent of the inflation of the arm determines the gripping force and geometry of the device.
216 Method and system employing strings of opposed gaseous-fluid inflatable tension actuators in jointed arms, legs, beams and columns for controlling their movements US13247 1987-02-10 US4784042A 1988-11-15 Henry M. Paynter
The method and system employ strings of tension actuators in opposed relationship for controlling motions or deflections of jointed members: for example, for controlling the motions of arms, legs and elephant trunks or flexible antennae in robots and for controlling the deflections of beams and columns in frames and structures. These opposed tension actuators are inflated with controlled air pressures which are oppositely varied from a predetermined common-mode pressure P.sub.o (initial fluid pressure level P.sub.o). In other words, as one tension actuator is being inflated with pressure increasing above P.sub.o, the opposed tension actuator is being inflated with pressure decreasing below P.sub.o for producing motion or deflection of the jointed member in one direction, and conversely for producing motion or deflection in the other direction. The opposed tension actuators have their ends anchored to rigid movable plates or struts containing sockets for the respective joints. By virtue of controlling the opposed actuators with a common-mode pressure level P.sub.o, they are always exerting a net compressive force on each joint, so advantageously permitting usage of simple, inexpensive, lightweight, non-capturing joints as shown. Moreover, the jointed member automatically returns to a predetermined midrange rest position whenever air pressures are returned to P.sub.o. A nearly uniform stiffness (or mechanical output impedance) is provided at all positions by controlling the opposed pressures to be P.sub.o +.DELTA.P and P.sub.o -.DELTA.P, where .DELTA.P is a corresponding increment above and below the initial (common-mode) level P.sub.o. In this way, precision open-loop proportional control is achieved.
217 Object manipulator US872493 1986-06-10 US4765795A 1988-08-23 Jack Rebman
An elongate main body section of the manipulator has its opposite ends respectively connected to a base section and an object support section. The main body section consists of elongate flexible rod members extending in generally parallel spaced relationship to each other and to the central axis of such section. The lower end portions of the rods are driven by drive mechanisms within the base section to selectively cause the main body section to undergo extension/retraction, bending and/or twisting movement in desired directions. The rod members may be resiliently flexible throughout their entire extent, or may be comprised of rigid sections interconnected by elastomeric joints. In one embodiment the drive mechanisms imparts rotation to the lower end portion of each rod member to produce twisting of the main body section, while in another embodiment axial movement imparted to the rods is reacted by an object support section having relatively moveable components to produce the twisting movement.
218 Flexible, extensible robot arm US485654 1983-04-18 US4551061A 1985-11-05 Ralph W. Olenick
A robot arm formed of a bundle of adjacent elastomeric tubes supplied independently with fluid pressure to force bending, extension or contraction. The tubes are maintained in parallel alignment by means of spaced apart parallel ribs through which the tubes pass. Parallel, spaced apart, rods extending through the ribs, but fixed at one end, have opposite free ends passing into position sensors. Bending and lengthwise changes in arm position may be sensed by the rods and used to control pressure in individual arms to correct or change arm position.
