US Patent:

20130317639, Nov 28, 2013
Filed:

Dec 14, 2011
Appl. No.:

13/994558
Inventors:

Sangeun Choi - Simsbury CT, US
Srinivas Nidamarthi - Auburn Hills MI, US
Michael M. Rickin - Shaker Heights OH, US
Assignee:

ABB TECHNOLOGY AG - Zurich
International Classification:

G05B 15/02
US Classification:

700109
Abstract:

A machine such as an industrial robot operates either in a stand-alone or in-production mode to perform a number of tests on a battery object having one of several different assembly levels and packaging geometries. The machine has selectable testing programs that correspond to various combinations of object assembly levels and geometries. The machine performs the tests either by coming into contact with a predetermined location on the conductive material of the object or viewing that location. The test results are analyzed to determining if retesting is necessary. After all of the tests are completed on an object, the tested object is assigned a grade and then sorted by grade. The tested objects may be kept at the machine location or sent on for further processing based on the assigned grade. After the testing is completed on one object, the machine tests the next object to be tested.

US Patent:

20100312391, Dec 9, 2010
Filed:

Jun 5, 2009
Appl. No.:

12/479185
Inventors:

Sangeun Choi - Simsbury CT, US
Thomas A. Fuhlbrigge - Ellington CT, US
William Eakins - Bloomfield CT, US
Gregory Rossano - Enfield CT, US
Assignee:

ABB Research Ltd. - Zurich
International Classification:

G06F 19/00
US Classification:

700254, 901 5, 901 9, 901 42, 901 46
Abstract:

A lead-through teaching device for an industrial robot is calibrated by moving the device to each of a predetermined number of reference poses. A controller responds to a signal from the device induced by gravity at each of the reference poses to calibrate the device to a predetermined coordinate frame. If necessary, a removable weight can be mounted to the device. The robot can hold either the tool that is to perform work on a workpiece or the workpiece. In those applications where the tool has a removable component, the lead-through teaching device can replace the removable component during its calibration to the predetermined coordinate frame.

G05B 15/02
B60L 53/16
B60L 53/66
G05D 1/02
H02J 7/00
Abstract:

Devices, methods and software for automated electrical connector positioning for electric vehicle (EV) charging are provided. Using, for example, the disclosed automatic charging device, a method for charging an EV includes determining receipt of an EV-side electrical connector to a charging zone of an EV charging environment. The method includes actuating a charger-side electrical connector from an initial position outside of the charging zone to a final position inside of the charging zone. The final position corresponds to the charger-side electrical connector matingly engaged with the EV-side electrical connector.

US Patent:

20210053455, Feb 25, 2021
Filed:

Aug 21, 2019
Appl. No.:

16/547218
Inventors:

- Baden, CH
Gregory A. Cole - West Hartford CT, US
William J. Eakins - Coventry CT, US
Sangeun Choi - Simsbury CT, US
Martin Krucinski - Glastonbury CT, US
Assignee:

ABB Schweiz AG - Baden
International Classification:

B60L 53/31
B60L 53/36
B60L 53/30
B60L 53/66
B60L 53/16
Abstract:

Systems and method for underside charging of electric vehicles (EVs) are provided. With the EV positioned in a charging environment having a ground surface, a floor unit device actuates an electrical connector toward a charge receptacle of an EV vehicle unit, and the vehicle unit actuates the charge receptacle toward the electrical connector. The actuation facilitates coupling between the connector and the charge receptacle. A flow of electrical current is initiated through the coupled connector and charge receptacle to charge the EV power storage device. Upon completion of the EV charging process, the electrical connector and the charge receptacle are actuated away from one another to facilitate decoupling therebetween.

US Patent:

20200331144, Oct 22, 2020
Filed:

Apr 16, 2019
Appl. No.:

16/385470
Inventors:

Carlos Martinez - South Windsor CT, US
Sangeun Choi - Simsbury CT, US
Assignee:

ABB Schweiz AG - Baden
International Classification:

B25J 9/16
Abstract:

Methods, systems, and software for controlling object picking and placement by a robot system are disclosed. The method includes assigning machine learning training data of a machine learning model for an object. The machine learning training data includes a plurality of known grasp location labels assigned to the object positioned in a plurality of different object poses. The method includes providing the object in a work space of the robot system. For the object in the work space in a first pose of the plurality of different object poses, the method includes: mapping a first candidate grasp location on the object; executing robotic movements for the first candidate grasp location on the object; and evaluating a result of the executing for the first candidate grasp location according to at least one predetermined performance criteria.

US Patent:

20200331709, Oct 22, 2020
Filed:

Apr 16, 2019
Appl. No.:

16/385592
Inventors:

- Baden, CH
Sangeun Choi - Simsbury CT, US
Carlos Martinez - South Windsor CT, US
Assignee:

ABB Schweiz AG - Baden
International Classification:

B65G 47/90
Abstract:

A grasping system includes a robotic arm having a gripper. A fixed sensor monitors a grasp area and an onboard sensor moves with the gripper also monitors the area. A controller receives information indicative of a position of an object to be grasped and operates the robotic arm to bring the gripper into a grasp position adjacent the object based on information provided by the fixed sensor. The controller is also programmed to operate the gripper to grasp the object in response to information provided by the first onboard sensor.
