Sensing The Tendon Tension Through The Conduit Reaction Forces

View page
US Patent:
8056423, Nov 15, 2011
Filed:
Nov 12, 2008
Appl. No.:
12/269552
Inventors:
Muhammad E. Abdallah - Houston TX, US
Lyndon Bridgwater - Houston TX, US
Myron A. Diftler - Houston TX, US
Douglas Martin Linn - White Lake MI, US
Robert Platt - Houston TX, US
Assignee:
GM Global Technology Operations LLC - Detroit MI
The United States of America as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC
International Classification:
G01N 3/08
US Classification:
73826
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.

Assignee:
GM Global Technology Operations LLC - Detroit MI
The United States of America as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC
International Classification:
G05B 19/04
US Classification:
700250, 700245, 700246, 700247, 700252, 700257, 446 95, 446284, 446327, 446465, 446473, 31856811, 31856813, 901 1, 901 30, 600 38, 706 44, 706 45
Abstract:
A robotic system includes a humanoid robot with robotic joints each moveable using an actuator(s), and a distributed controller for controlling the movement of each of the robotic joints. The controller includes a visual perception module (VPM) for visually identifying and tracking an object in the field of view of the robot under threshold lighting conditions. The VPM includes optical devices for collecting an image of the object, a positional extraction device, and a host machine having an algorithm for processing the image and positional information. The algorithm visually identifies and tracks the object, and automatically adapts an exposure time of the optical devices to prevent feature data loss of the image under the threshold lighting conditions. A method of identifying and tracking the object includes collecting the image, extracting positional information of the object, and automatically adapting the exposure time to thereby prevent feature data loss of the image.

Bidirectional Tendon Terminator

US Patent:
8276958, Oct 2, 2012
Filed:
Nov 12, 2008
Appl. No.:
12/269579
Inventors:
Chris A. Ihrke - Hartland MI, US
Douglas Martin Linn - White Lake MI, US
Lyndon Bridgwater - Houston TX, US
Assignee:
GM Global Technology Operations LLC - Detroit MI
The United States of America as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC
International Classification:
B25J 15/00
B66C 1/00
US Classification:
294111, 7449005, 7449006
Abstract:
A bidirectional tendon terminator that has particular application for terminating a tendon that actuates a finger in a robotic arm. The tendon terminator includes a cylindrical member having an internal channel through which a single continuous piece of the tendon extends. The internal channel of the tendon terminator includes a widened portion. A ball is placed in the tendon strands, which causes the tendon to expand, and the ball is positioned within the widened portion of the channel. Pulling on the tendon operates to either open or close the finger of the robotic arm depending on which direction the tendon is pulled. In one specific embodiment, the cylinder includes two cylindrical pieces that are coupled together so that the ball can be positioned within the channel and the cylindrical member has an entire circumference of material.

Tendon Tension Sensor

US Patent:
8371177, Feb 12, 2013
Filed:
Sep 30, 2008
Appl. No.:
12/241309
Inventors:
Chris A. Ihrke - Hartland MI, US
Lyndon Bridgwater - Houston TX, US
Robert Platt - Houston TX, US
Assignee:
GM Global Technology Operations LLC - Detroit MI
The United States of America as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC
International Classification:
G01B 5/30
US Classification:
73760, 73826
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.
