Abstract: A flexible arm particularly a robot arm comprising a plurality of elements arranged in a series with adjacent elements in abutting relationship, said elements being interconnected via cables and if desired a power transferring actuating device. The arm has very good rigidity in the bending plane of each element and high torsional resistance together with low manufacturing costs. Each element is designed with opposed single or double-curved segments, or flat surfaces, or combinations thereof with the curved surfaces of each segment engaging the curved or flat surfaces of the adjacent segments, whereby the elements when actuated by the power transferring device have a rolling motion relative to each other.

Abstract: A telescopic telemanipulator of the master-slave type, wherein the slave arm is equilibrated by means of at least one counterweight mounted on a link articulated to the traversing block on the master arm side, the counterweight moving along the link when an offsetting is introduced between the length of the slave arm and that of the master arm; at least a second counterweight is mounted adjacent the first counterweight on another link, such counterweight moving along the link when a variation in the length of the slave arm is controlled from the master arm.The telemanipulator has application for the remote-controlled handling, among other things, of radioactive products.

Abstract: The disclosed mechanism includes multiple links having adjustable-length drive units connected in series and operated coordinately. The illustrative form of adjustable-length drive unit has oppositely extending elements oppositely threaded in a body that is secured to a mount, the oppositely extending elements being keyed to each other for conjoint rotation that allows extension and contraction of the drive unit. In one form, successive drive units of successive links produce tilting of articulated links in respective planes perpendicular to each other.

Abstract: An amusement game device generally in the configuration of a dragon-like figure including a body portion having an open cup portion therein, an elongated flexible neck member which normally extends outwardly from the body portion, and a head portion which is attached to the neck member and includes an outwardly extending hook-like tongue. A tail on the device which extends rearwardly from the body portion is manipulatable to curl the neck member upwardly and rearwardly to move the head portion to the interior of the cup portion or slightly thereabove whereby ring-like game elements disposed on the hook-like tongue may be deposited in the cup portion by manipulating the tail.

Abstract: A flexible arm for a program controlled manipulator, with a hydraulic rotary actuator supported on an inflexible arm, a first arm member secured to a rotary shaft of the actuator, a second arm member connected swingably to the first arm member by way of a shaft, a third arm member connected rotatably to the second arm member, a link member connected rotatably to the first and third arm member, and a working tool mounted to the free end of the flexible arm.

Abstract: An amusement game device includes a labyrinth structure and a pair of elongated resiliently flexible substantially coextensive strips which are interconnected at one end thereof. The device is operable to effect the selective independent longitudinal advancement and retraction of each of the strips to cause the interconnected ends thereof to be selectively turned and thereby guided through the labyrinth structure. Game play is effected by advancing the strips through the labyrinth structure to engage and manipulate or retrieve game elements positioned therein through the use of a magnet or the like attached to the interconnected strip ends.

Abstract: An articulated robot comprises one or more articulation angles that can assume two states on the occasion of the same position or attitude of an object being controlled. A change from one to the other of the above described two states is taught by operating an operation panel and the respective driving means of two arms constituting one articulation angle are controlled based on the above described teaching information so that the articulation angle may be changed from one state to the other state, whereby rotation of the respective arms is controlled.

Abstract: An industrial robot having an arm formed as a hollow joint-free tube which is oval in cross section and made from a material that will provide structural rigidity to enable the arm to support a work tool and provide controlled bending thereof when the hollow interior of the tube is subjected to a variation in pressure.

Abstract: A flexible arm particularly a robot arm comprising a plurality of elements engaging each other and being arranged in a series, said elements being interconnected via cables and if desired a power transferring actuating device. The purpose of the invention is to provide an arm having very good rigidity in the bending plane of the element and a high torsional resistance together with lower manufacturing costs as compared to conventional robot arms. This has been achieved by each element being designed with arched opposed single-or double-curved segments which with the curved surfaces of each segment engaging the surfaces of the adjacent segments, whereby the elements are arranged when actuated by the power generating and/or power transferring device to have a rolling motion relative to each other.

Abstract: This invention relates to a multi-purpose mechanical hand mainly for industrial applications and able to grip pieces of various shapes and dimensions. The mechanical hand according to the invention is constituted by at least three fingers, each finger being provided with articulated phalanges and a gripping element, the fingers being controlled by a system which enables the degree of tightening and the grip to be controlled by a force threshold method on the basis of the signal representing the force exerted by the individual finger.

Abstract: The electrical spot welding manipulator is assembled of a base, a rotary support on the base, an arm hinged to the support and rotatable at right angles to the support, a rotatable hollow member inside the arm, a column arranged inside the hollow arm for rotation about its axis, a working head mounted on the column and being rotatable about two secondary axes, movable welding grips mounted on the head, actuator elements, for activating respective movable members, and a welding transformer arranged in the arm and connected to the welding grips by flexible conductors.

Abstract: The disclosed mechanical arm comprises a base having mounted thereon a plurality of pivotally connected links, each having its own individual motor operatively connected through driving kinematic chains with said links, and a tensioning mechanism including a tensioning member and kinematic chains connecting said tensioning member with the links; said tensioning mechanism being provided with differential gears in a number equalling that of said driving kinematic chains tensioned by said tensioning member, one output of each said differential gears being connected to said individual motor, and two other outputs thereof being connected to the preceding and successive ones of said differential gears; the two unoccupied outputs of the terminal ones of said differential gears being connected, respectively, to said base and said tensioning member.The invention is primarily intended for automation of main and auxiliary operations in various industries, e.g. for handling of production tools and equipment.
