  • Patent number: 9949749
    Abstract: A method for capturing an object in a cavity in a patient is described. The method includes advancing a ureteroscope into the cavity containing the object. A basket is advanced through a working channel of the ureteroscope. The basket is opened within the cavity and is positioned so as to enclose the object. Then, two actions are performed simultaneously. The basket is collapsed while simultaneously the basket tool is advanced forward so that the object remains within the basket, ideally near the center of the basket, as the basket closes around the object. Once the object is captured, the basket is retracted to remove the object out of the cavity. Further, this process may be automated by having the method carried out by robotic arms acting in tandem, with one or more robotic arms advancing the basket tool or ureteroscope, and another robotic arm collapsing the basket.

  • Publication number: 20120041595
    Abstract: A pistol-grip controller for the control of a robotic or virtual hand has multiple dual-action switching mechanisms positioned to simulate intuitively the motion of grasping and releasing an object. An externally-projecting switch trigger of each switching mechanism is hook-shaped to facilitate the operator donning and doffing the controller. These switches move in response to gripping and releasing movements of the associated fingers so as to close or open peripherals (fingers) of the end effector hand. A rocker switch allows an operator to toggle conveniently between commonly used modes of a virtual or robot hand, or the like. The mode toggling is complemented by a control to adjust between the commonly used modes of operation. To make the manipulation of the end effector more intuitive, the controller remaps the switching mechanisms to different functionalities on the end effector based on the mode of operation. The transition between switch to end effector mappings is hysteretic.

  • Patent number: 7862522
    Abstract: A Sensor glove is an instrument, in the same way that a piano is an instrument. The Sensor glove is purchased and the owner then learns to use it and the sensors therein to develop the performance of a sound, character or model, or to “conduct” or “play” the sensor movements and experience the response of the model in real time. Several performers with a number of the Sensor glove can control over 200 motors or hundreds of control points on a character at one time, manipulate audio data, or computer images etc. The characteristics of the sensors on the gloves can be adjusted to the needs and demands of the wearer or the many performer and wearers in those venues where multiple performers are used with many gloves to control or produce the motions and sounds of many distinct characters in a screen play.

  • Patent number: 7810791
    Abstract: A servo motor driven hoist includes a float mode in which a load is raised lowered in response to manually applied forces on the load exerted by an operator in which forces applied to the load as a result of accelerations of the load generated by hoist movement of said load are compensated for by sensing the accelerations and computing the forces resulting therefrom, and subtracting those forces from the sensed total magnitude of forces acting on the load to eliminate the effects of dynamically generated forces when in the float mode.

  • Publication number: 20100080669
    Abstract: An input device for a robotic surgical instrument includes an operator input on a handle that is rotatably supported by a supporting link structure. A primary winding of a rotary transformer is fixed to the supporting link structure and connected to an electric power source. A secondary winding is fixed to the handle. An axial passage extends through the primary and secondary windings. An optical data transmitter is connected to the operator input to transmit data from the operator input through the axial passage. The secondary transformer winding provides power to the optical data transmitter without physical contact. An optical data receiver fixed to the supporting link structure receives data from the optical data transmitter transmitted through the axial passage in the rotary transformer without physical contact. The transmission of power and data without physical contact allows the handle to rotate continuously.

    Abstract: The invention concerns an industrial robot (4) comprising a machining tool (2) attached to one hand (3) of the robot, designed to perform a hydraulic-driven movement relative to the hand (3) and connected therefor to a hydraulic unit (10). The hydraulic unit (10) is placed directly on a mobile part of the robot, in particular directly on the robot hand (3). Therefore there is no more need for hydraulic supply lines along the arm of the robot. Further, when the robot hand (3) changes tool, no separation of hydraulic lines is required. The machining tool (2) is in particular a device for placing blind rivets, thereby enabling an entirely automated process for placing blind rivets.

    Abstract: The invention relates to an arm exoskeleton comprising a moving system of joints placed in parallel with the joints of the human arm, the exoskeleton comprising a shoulder exoskeleton, an elbow exoskeleton, and a wrist exoskeleton. In all, the exoskeleton has sixteen joints providing sixteen degrees of freedom. A support worn on the torso of a human operator comprises a rigid front plate and a rigid back plate. The shoulder exoskeleton has its proximal end fixed to the front plate, whereby the front plate provides a fixed reference for all movements of the exoskeleton, and the wrist exoskeleton is fixed to a rigid glove worn on the hand of the operator. Active joints are controlled by flexible cable tendons bridging the exoskeleton, said tendons themselves being actuated by control units disposed on the rigid back plate. Inflatable cushions prevent the wrist exoskeleton and the shoulder exoskeleton from moving relative to the arm of the operator.
