  • Publication number: 20100161127
    Abstract: A system and method for providing multiple priority impedance control for a robot manipulator where impedance laws are realized simultaneously and with a given order of priority. The method includes a control scheme for realizing a Cartesian space impedance objective as a first priority while also realizing a joint space impedance objective as a second priority. The method also includes a control scheme for realizing two Cartesian space impedance objectives with different levels of priority. The method includes instances of the control schemes that use feedback from force sensors mounted at an end-effector and other instances of the control schemes that do not use this feedback.

  • Publication number: 20100152898
    Abstract: A system and method for controlling tendon-driven manipulators that provide a closed-loop control of joint torques or joint impedances without inducing dynamic coupling between joints. The method includes calculating tendon reference positions or motor commands by projecting a torque error into tendon position space using a single linear operation. The method calculates this torque error using sensed tendon tensions and a reference torque and internal tension. The method can be used to control joint impedance by calculating the reference torque based on a joint position error. The method limits minimum and maximum tendon tensions by projecting the torque error into the tendon tension space and then projecting ii back into joint space.

  • Publication number: 20100121222
    Abstract: A technique that determines the tension in a tendon using a conduit reaction force applied to an end of a conduit through which the tendon is threaded. Any suitable tendon tension sensor can be employed that uses the conduit reaction force for this purpose. In one non-limiting embodiment, the tendon tension sensor includes a cylindrical strain gauge element and a force member mounted to an end of the conduit. The force member includes a cylindrical portion having a bore and a plate portion, where the cylindrical portion is inserted into a bore in the strain gauge element. The tendon is threaded through the strain gauge element and the force member. A strain gauge is mounted to the strain gauge element and measures the reaction force when tension on the tendon causes the strain gauge element to be pushed against the force member.

  • Publication number: 20100081969
    Abstract: A tendon tension sensor that has particular application for measuring tension on a tendon employed in a robotic arm. The tension sensor includes an elastic element having a curved channel through which the tendon is threaded. The elastic element also includes a center portion on which strain gauges are mounted that measure the strain on the elastic element. Tension on the tendon causes the center portion of the elastic element to flex or bend, which is measured by the strain gauges providing an indication of the tension in the tendon.

  • Publication number: 20070241318
    Abstract: A fencing system includes a post mount mountable on a foundation and having a vertically extending outer surface. A post insert sits atop the post mount and has an outer surface disposed outwardly of the post mount outer surface. The post insert has an upper sidewall which extends upwardly of the post mount and defines an upwardly opening cavity. A post includes a sidewall having an inner surface defining a cavity therein in which the post mount and post insert are slidably received with the outer surface of the post insert preferably closely adjacent the post inner surface. A rail is mounted via a rail mounting bracket to the post insert. Threaded fasteners extend from the rail mounting bracket through respective holes in the post and are threaded into mounting holes in the post insert to provide a strong connection for the mounting of the rail mounting bracket and rail.

  • Publication number: 20070241315
    Abstract: A rail clip for connecting a horizontal fence rail to a vertical fence post. The rail clip comprises a housing that is slidably engaged with a mounting base secured to the fence post. The clip further includes a L-shaped mounting bracket, a first leg of which is inserted into the housing between the mounting base and the rail clip, and a second leg which abuts the underside of the housing. An end of the rail is inserted into a chamber formed in the housing and a fastener is used to secure the second leg of the mounting bracket, the housing and the end of the rail together. The mounting bracket aids in preventing the rail and rail clip from dislodging from each other and from the fence post when a lateral force is applied to the rail.

  • Publication number: 20070145342
    Abstract: A mounting attachment for connecting a picket to an angled rail. The mounting attachment comprises a base having an aperture therethrough and into which the picket is inserted. A spring-biased retaining member is provided on the base and is adapted to engage an outer surface of the picket when it is inserted into the aperture. The retaining member urges the picket into contact with the wall of the base which defines the aperture, thus preventing the picket from moving within the aperture and substantially parallel to the longitudinal axis of the rail.

  • Publication number: 20070100206
    Abstract: A method provides flow to multiple channels in an endoscope during an endoscope decontamination procedure. A member is inserted into a chamber in a body of an endoscope through an opening into the chamber, the chamber being intersected by a first lumen and a second lumen. The member separates fluidly the first lumen from the second lumen. Fluid is flowed through a first channel through the member into the first lumen and through a second channel through the member into the second lumen. Additional lumens can be so treated at the same time. Fluids can include detergents and other cleaning fluids, disinfectants and sterilants.
