  • Patent number: 11433959
    Abstract: A four-wheeled articulated steering vehicle for terrain exploration. The four-wheeled articulated steering vehicle has a pair of robotic tethered two-wheel vehicles that dock, lock, and drive long distances as the four-wheeled, articulated steering vehicle. Two actuated docking mechanisms attached on opposite ends of a central module of the four-wheeled vehicle enable “sit/stand” functionality. The “sit” configuration is achieved by aligning each dock mechanism parallel or nearly parallel to the surface, allowing two-wheel vehicle to detach and explore while the other remains docked and serves as a backup. While ‘sitting’, the central module rests on the ground and is outfitted with shovel-style wedges for passive anchoring. In order to “stand”, the exploring two-wheel vehicle reattaches, locks, and both dock mechanisms are rotated until each two-wheel vehicle's caster arm is upright and the central module is lifted off the ground.

  • Patent number: 10131183
    Abstract: A wheel includes a circular wheel main body and at least one grouser. The at least one grouser is provided along an outer circumference of the wheel main body and has a contact surface capable of drawing a first tangent line. The first tangent line is inclined opposite to a rotational direction of the wheel main body from the center line of the wheel main body.

  • Patent number: 6056108
    Abstract: A flexible parts feeder includes a flexible membrane for supporting parts and defining a selection zone where the positional state of parts is analyzed by a machine vision system. The output of the sensor is used to control a transformer that selectively applies impulse energy to the flexible membrane so as to change the positional states of at least some parts in the selection zone to a desired positional state. Those parts having the desired positional state are selected and removed from the membrane by a robot.
