Patent number: 9850108Abstract: A movement device is moved along an X axis and a Y axis by providing a sensor configured to measure angle of rotation of at least one of a first and a second kinematic link about a respective axis of rotation. A force is imparted on the first and second kinematic links such that an angular displacement of the first and second kinematic links about the respective axis of rotation is achieved. The angular displacement of the first and second kinematic links about the respective axis of rotation is determined. The movement device is moved along the X axis and/or the Y axis in response to the determination of the angle of rotation of the first and second kinematic links about the respective axis of rotation until first and second kinematic links are vertical.Type: GrantFiled: March 15, 2017Date of Patent: December 26, 2017Assignees: GM Global Technology Operations LLC, Universite LavalInventors: Dalong Gao, Alexandre Lecours, Thierry Laliberte, Simon Foucault, Clement Gosselin, Boris Mayer-St-Onge, Roland J. Menassa, Pierre-Luc Belzile

Patent number: 9308645Abstract: A method of inferring intentions of an operator to move a robotic system includes monitoring the intention of the operator, with a controller. The intention of the operator is inferred to be one of a desired acceleration and a desired deceleration. The intention of the operator is also as a desired velocity. Admittance parameters are modified as a function of at least one of the inferred acceleration, deceleration, and velocity.Type: GrantFiled: March 7, 2013Date of Patent: April 12, 2016Assignees: GM Global Technology Operations LLC, Universite LavalInventors: Alexandre Lecours, Boris Mayer-St-Onge, Clement Gosselin, Dalong Gao

Patent number: 9266440Abstract: A robotic charging station for charging a battery of an electric vehicle includes a base plate, a riser coupled with the base plate and extending substantially transverse to the base plate, and a robotic arm. The robotic arm extends from the riser and supports an end effector. The end effector includes a plurality of electrical contacts configured to couple with a receptacle disposed on the electric vehicle. The robotic arm is configured to move the end effector in three degrees of motion.Type: GrantFiled: May 31, 2012Date of Patent: February 23, 2016Assignees: GM Global Technology Operations LLC, Universite LavalInventors: Dalong Gao, Neil David McKay, Matthew J Reiland, Simon Foucault, Marc-Antoine LaCasse, Thierry Laliberte, Boris Mayer-St-Onge, Alexandre Lecours, Clement Gosselin, David E.

Patent number: 8985354Abstract: A movement system includes a bridge crane, a trolley, and a movement device. The movement device includes an attachment portion, a plurality of housings, first and second curved elements, a cable, and a cable angle sensor. The curved elements are pivotally attached to housings and perpendicularly overlap with one another such that a first slot defined in the first curved element is perpendicular to a second slot defined in the second curved element. The first curved element is pivotable about a first axis and the second curved element is configured to pivot about a second axis. The cable extends from the attachment portion and through each of the slots. The cable is pivotable to angularly displace at least one of the curved elements about a respective axis. The cable angle sensor is configured to measure the angular displacement of the at least one of the first and second curved elements.Type: GrantFiled: October 31, 2012Date of Patent: March 24, 2015Assignees: GM Global Technology Operations LLC, Univerersite LavalInventors: Alexandre Lecours, Simon Foucault, Thierry Laliberte, Clement Gosselin, Boris Mayer-St-Onge, Dalong Gao, Roland J.

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.
