  • Publication number: 20230233274
    Abstract: Various embodiments for a continuum manipulator are described for use in robotic surgical systems or other desired applications. The continuum manipulator includes an extensible continuum manipulator (ECM) body comprising a plurality of subsegments serially connected to one another. Adjacent ones of the subsegments are coupled by rack-and-pinion transmission sets that are configured to propagate subsegment motion to downstream ones of the subsegments. A multi-chain flexible parallel mechanism is provided in each of the subsegments that is configured to generate a desired spatial bending and extension mobility for each of the subsegments.

  • Publication number: 20220203518
    Abstract: An articulated multi-link robotic tail (MLRT) system is provided comprising a rigid housing, an actuation unit coupled to the rigid housing, and an MLRT having a proximal end that is coupled to the rigid housing and a distal end opposite the proximal end. The MLRT comprises N segments, where N is a positive integer that is greater than or equal to one. Each segment comprises i links, where i is a positive integer that is greater than or equal to two. Each link is mechanically coupled to an actuator of the actuation unit and capable of being actuated by the actuator to which it is mechanically coupled to adjust a pitch, yaw and roll of the MLRT. The articulated MLRT system is well suited for being integrated with a mobile robot to assist in stabilizing and maneuvering the mobile robot.
