  • Patent number: 11788581
    Abstract: A bearing unit is provided with a strain element for torque detection. The strain element is provided with a first annular part attached to a rotation-side member, a second annular part attached to a load-side member, and a plurality of ribs serving as strained parts linking the first annular part and the second annular part together. One of an inner race and an outer race is integrally formed on the first annular part of the strain element. Deformation, which occurs in the ribs of the strain element due to torque exerted on the rotation-side member from the load-side member, is detected by a strain gauge, etc., and converted to torque. The strain element for torque detection can be incorporated into a motor, a reducer, or another rotary propulsion unit without the need for a dedicated installation space and without the need for fastening fittings, etc.

  • Patent number: 8412376
    Abstract: A method is provided for distributing tension among tendons of a tendon-driven finger in a robotic system, wherein the finger characterized by n degrees of freedom and n+1 tendons. The method includes determining a maximum functional tension and a minimum functional tension of each tendon of the finger, and then using a controller to distribute tension among the tendons, such that each tendon is assigned a tension value less than the maximum functional tension and greater than or equal to the minimum functional tension. The method satisfies the minimum functional tension while minimizing the internal tension in the robotic system, and satisfies the maximum functional tension without introducing a coupled disturbance to the joint torques. A robotic system includes a robot having at least one tendon-driven finger characterized by n degrees of freedom and n+1 tendons, and a controller having an algorithm for controlling the tendons as set forth above.

    Abstract: A robot has a track assembly having tracks configured to move the robot in a first direction and a wheel assembly having wheels configured to move the robot in a second direction orthogonal to the first direction. A toggling assembly switches between the track assembly and the wheel assembly. The robot modules can mate with each other. The robot module has an elongated shaft with a head and a narrow neck. The shaft extends outward from the side of the robot module. A mating robot module has a clamping mechanism with opposing clamps which in an opened position receive the shaft. In a closed position, the clamps define an opening which matches and engages the cross-section of the neck of the elongated shaft. The clamping mechanism has a drive mode to drive the module, a clamping mode for docking, and neutral mode for alignment prior to clamping.

  • Patent number: 8271130
    Abstract: An input device includes a handle coupled to a base by a linkage. The handle is manually movable relative to the base to provide a position input. The linkage has a plurality of links including a redundant link that permits internal motion of the linkage such that the linkage can move without moving the handle relative to the base. When a distance between the handle and a handle stop position is less than a threshold distance, a handle stop applies a first load to the handle. A drive system applies a second load to the redundant link responsive to the first load to create internal motion of the linkage that increases a distance between the handle and a handle stop position. The second load may be proportional to a cosine of an angle between a handle axis of motion and a redundant link axis of motion.
