  • Patent number: 7946902
    Abstract: An articulated walking device, configured for movement across a surface, includes a frame and a plurality of leg assemblies movably coupled with the frame so as to at least partially support the frame for movement across the surface. Each leg assembly includes a leg member configured to rotate with respect to the frame about a joint. The joint is formed by a pin passed through an at least generally hour glass shaped aperture to provide rotational movement of the leg member with respect to the frame about at least first and second axes of rotation intersecting in the joint. A drive mechanism is operatively engaged with the plurality of leg assemblies so as to actuate each of the leg members to rotate about the first and second axes in a like, predetermined, repeatable cycle of movement. At least some of the leg members are out of phase with other leg members to produce an anatomic-like gait of the toy device upon actuation of the drive mechanism.

  • Publication number: 20040063382
    Abstract: An ambulatory mechanical leg system drives a mechanical leg (100, 21) with a crank (91) to pivot about a pivot axis (102) to produce uniform rectilinear motion at the distal end (41) of the leg (100, 21) during a stride stroke (51) portion of a crank revolution or cycle and then lifts the distal end (41) to fast-return it in a step stroke (61) during the remainder of the revolution to a starting point for the next stride stroke (51). The crank (91), leg (100, 21) and pivot axis (102) sizes and proportional lengths or distances are modeled to an angular profile that produces nearly constant velocity, and mechanical structures maintain nearly rectilinear motion, of the distal end (41) of the leg (100, 21) during the stride stroke (51).

  • Patent number: 6705917
    Abstract: An apparatus that is capable of achieving self-synchronized walking and turning includes a first motor that is attached to the apparatus that is in communication with a first limb and a second motor, independent from the first motor, that is attached to the apparatus and is in communication with a second limb. Initially, the lateral phase differential is set at 180 degrees and is maintained by a dampening mechanism that is interposed between the two limbs, or other movable members mechanically linked thereto, making sure that apparatus walks in a straight line. Regulators may forcibly upset this balance by speeding up one of the motors, thereby overcoming the force exerted by the damper mechanism, causing one limb to move faster than the other limb. This results in the apparatus turning in a prescribed radius.

    Abstract: The present invention relates to animated devices that include one or more electroactive polymer transducers. When actuated by electrical energy, an electroactive polymer produces mechanical deflection in one or more directions. This deflection may be used to produce motion of a feature included in an animated device. Electroactive polymer transducers offer customizable shapes and deflections. Combining different ways to configure and constrain a polymer, different ways to arrange active areas on a single polymer, different animated device designs, and different polymer orientations, permits a broad range of animated devices that use an electroactive polymer transducer to produce motion.

  • Patent number: 5628668
    Abstract: Complicated movements of a walking doll such as going frontward or backward while making a big turn or making a turn in place is possible if the walking doll includes a body with a gear unit for supporting and driving a pair of feet having the same length and moved in an oscillating manner in the front/rear direction with respect to the body without restraint. The doll stands erect on the feet since they have surfaces which stay in contact with the floor. These surfaces have a curvature in the oscillating direction and the curvature is constantly in contact with the floor. A member for adjusting the position of a gravitational center of the doll is swiveled or deformed on a first plane parallel to the oscillation direction and another plane orthogonal to the first plane. This can three-dimensionally shift the center of gravity frontward or backward or to a side region of the doll.

  • Patent number: 5378189
    Abstract: A toy animal which can mimic the walking movement of real animals, including a flexible housing accommodating therein a driving device consisting of a body and various elements supported by the body. These elements include a battery set, a motor, a retarding device, and a main shaft retarded and driven by the retarding device. The main shaft has a cam in the middle thereof, with two eccentric wheels provided at either end of the main shaft. The cam drives a tail rod at a tail shaft of the body to swing left and right, while the two eccentric wheels respectively drive a left foot support and right foot support pivotally disposed on a pair of side shafts at either side of the body to alternately oscillate back and forth. Each foot support has a slide plate which, when the foot support swings forward, projects from the sole and lifts up the foot support so that when the foot support swings backward, a forward thrust force is produced.

  • Patent number: 5318471
    Abstract: A robotic joint for use in toys or other robotic assemblies to provide locomotion to animated figures, sub-assemblies, and toy construction building sets. The robotic joint is particularly adaptable because one side of the joint carries the motor that is powering the joint. It also provides for four-way action in a joint in a very compact space by attaching a motorized joint directly to the shaft of another motor. It can also provide omni-directional action in a joint, since each motor turns the shaft or turns the motor housing based on the amount of resistance applied to the shaft. This can be demonstrated in a joint that is used to support a leg in which the joint has two motors attached by their shafts, perpendicular to each other in the same joint. A joint structure is provided in which two parallelograms are placed substantially perpendicular to one another to distribute the weight.
