  • Publication number: 20170129110
    Abstract: A robotic end effector includes a finger and at least one actuator. The finger extends from a proximal end to a distal end along a finger axis. The finger includes a first phalanx proximate the proximal end, a second phalanx proximate the distal end, and a knuckle joint including at least one vertebra interposed between and separating the first and second phalanxes. The knuckle joint is configured to permit the second phalanx to pivot relative to the first phalanx about a pivot axis transverse to the finger axis. Each vertebra has an axial thickness extending along the finger axis and a lateral width extending perpendicular to its axial thickness, and its lateral width is greater than its axial thickness. The at least one actuator is operable to move the second phalanx relative to the first phalanx about the pivot axis.

  • Publication number: 20160311479
    Abstract: A wheel assembly for a remote vehicle comprises a wheel structure comprising a plurality of spokes interconnecting a rim and a hub. The spokes comprise at least one slit extending therethrough radially inward from the rim to the hub. The assembly also comprises a flipper structure comprising an arm, a plurality of legs, and an attachment base. The plurality of legs and the attachment base comprise a four-bar linkage. The assembly further comprises an insert comprising a bore with a flat surface that tapers outward from a top portion to a bottom portion of the insert. The insert being configured to couple the flipper structure to the wheel structure via an axle on the remote vehicle and prevent backlash between the axle and the flipper structure. The flipper structure being configured to transmit axial forces to the wheel structure. The wheel structure being configured to absorb radial and axial forces.

  • Publication number: 20160221197
    Abstract: A robot includes a support, a movable member coupled to the support to permit gimbal rotation about a pitch axis and a yaw axis, and first and second linear actuators connected to each of the support and the movable member and operable to rotate the movable member about the pitch axis and the yaw axis. The first linear actuator is pivotally attached to the movable member at a first pivot point. The second linear actuator is pivotally attached to the movable member at a second pivot point. The first and second pivot points are each angularly offset from the pitch axis and the yaw axis by about 45 degrees and are located on the same side of the pitch axis.

  • Patent number: 9228640
    Abstract: A transmission assembly comprises: a motor; a shift actuator mechanism coupled to the motor; a sun gear coupled to an output shaft of the motor; a first magnet assembly coupled to the sun gear; a ring gear assembly coupled to a shift coupler, the shift coupler being configured to engage via the shift actuator mechanism; a second magnet assembly coupled to a housing face plate, the housing face plate being coupled to an output gear box; and a planet carrier coupled to an output pinion in communication with the output gearbox. The planet carrier comprises at least one planet gear. In a first mode, the ring gear is locked to the first magnet assembly and configured to rotate with the sun gear, the ring gear being configured to prevent the rotation of the at least one planet gear about its own axis causing the planet carrier to rotate at the same speed as the sun gear.

  • Patent number: 9216781
    Abstract: Configurations are provided for vehicular robots or other vehicles to provide shifting of their centers of gravity for enhanced obstacle navigation. A robot chassis with pivotable driven flippers has a pivotable neck and sensor head mounted toward the front of the chassis. The neck is pivoted forward to shift the vehicle combined center of gravity (combined CG) forward for various climbing and navigation tasks. The flippers may also be selectively moved to reposition the center of gravity. Various weight distributions allow different CG shifting capabilities.
