Patent number: 8644980Abstract: The cable lift system provides assistance to movement of a flexibly suspended payload actuated by operator input into one or more sensing devices attached to the payload. The sensing device is configured to collect information about the typical push-pull and lift-lower motions of an operator moving the payload horizontally and/or vertically, such that the operator's input to the sensor is intuitive and is provided in a manner which is substantially transparent to the operator. The assist mechanisms included in the system are actuated by a controller processing signals received from the one or more sensing devices on the payload. Movement assistance is provided such that the manual effort required by the operator to overcome the inertia of the payload in a starting or stopping event is substantially relieved, thus minimizing the ergonomic impact of the starting and stopping events on the operator.Type: GrantFiled: November 30, 2009Date of Patent: February 4, 2014Assignees: GM Global Technology Operations LLC, Universite LavalInventors: Dalong Gao, Diana Marie Wegner, Roland J.

Patent number: 8392023Abstract: A robotic system includes a robot for moving a payload in response to a calculated input force. Sensors in respective sensor housings are connected to a handle, each sensor including a light emitter and receiver. The sensors measure a light beam received by a respective receiver. A controller calculates the calculated input force using received light. Each sensor housing modifies an interruption of the light beam in a sensor when the actual input force is applied, and the controller controls the robot using the calculated input force. A method of controlling the robot includes emitting the light beam, flexing a portion of the sensor housing(s) using the actual input force to interrupt the light beam, and using a host machine to calculate the calculated input force as a function of the portion of the light beam received by the light receiver. The robot is controlled using the calculated input force.Type: GrantFiled: November 30, 2009Date of Patent: March 5, 2013Assignees: GM Global Technology Operations LLC, Universite LavalInventors: Vincent Duchaine, Noemie Paradis, Thierry Laliberte, Boris Mayer-St-Onge, Clement Gosselin, Dalong Gao
