Patent number: 7610108Abstract: A method for providing independent static and dynamic models in a prediction, control and optimization environment utilizes an independent static model (20) and an independent dynamic model (22). The static model (20) is a rigorous predictive model that is trained over a wide range of data, whereas the dynamic model (22) is trained over a narrow range of data. The gain K of the static model (20) is utilized to scale the gain k of the dynamic model (22). The forced dynamic portion of the model (22) referred to as the bi variables are scaled by the ratio of the gains K and k. The bi have a direct effect on the gain of a dynamic model (22). This is facilitated by a coefficient modification block (40). Thereafter, the difference between the new value input to the static model (20) and the prior steady-state value is utilized as an input to the dynamic model (22). The predicted dynamic output is then summed with the previous steady-state value to provide a predicted value Y.Type: GrantFiled: February 21, 2006Date of Patent: October 27, 2009Assignee: Rockwell Automation Technologies, Inc.Inventors: Eugene Boe, Stephen Piche, Gregory D.

Patent number: 7130718Abstract: A method for an industrial robot to increase accuracy in movements of the robot. A first path is formed by bringing a tool supported by the robot to adopt a plurality of generated positions. A plurality of observed positions of the tool moving along the first path are determined. A second path is formed of the determined tool positions. A correction is determined by a path deviation between geometrically determined positions in the first path and the second path.Type: GrantFiled: April 9, 2001Date of Patent: October 31, 2006Assignee: ABB ABInventors: Svante Gunnarsson, Mikael Norrlof, Geir Hovland, Ulf Carlsson, Torgny Brogardh, Tommy Svensson, Stig Moberg

Patent number: 7117067Abstract: Methods for operating robotic devices (i.e., “robots”) that employ adaptive behavior relative to neighboring robots and external (e.g., environmental) conditions. Each robot is capable of receiving, processing, and acting on one or more multi-device primitive commands that describe a task the robot will perform in response to other robots and the external conditions. The commands facilitate a distributed command and control structure, relieving a central apparatus or operator from the need to monitor the progress of each robot. This virtually eliminates the corresponding constraint on the maximum number of robots that can be deployed to perform a task (e.g., data collection, mapping, searching). By increasing the number of robots, the efficiency in completing the task is also increased.Type: GrantFiled: April 16, 2003Date of Patent: October 3, 2006Assignee: iRobot CorporationInventors: James McLurkin, Jennifer Smith

Patent number: 7050866Abstract: A method for providing independent static and dynamic models in a prediction, control and optimization environment utilizes an independent static model (20) and an independent dynamic model (22). The static model (20) is a rigorous predictive model that is trained over a wide range of data, whereas the dynamic model (22) is trained over a narrow range of data. The gain K of the static model (20) is utilized to scale the gain k of the dynamic model (22). The forced dynamic portion of the model (22) referred to as the bi variables are scaled by the ratio of the gains K and k. The bi have a direct effect on the gain of a dynamic model (22). This is facilitated by a coefficient modification block (40). Thereafter, the difference between the new value input to the static model (20) and the prior steady-state value is utilized as an input to the dynamic model (22). The predicted dynamic output is then summed with the previous steady-state value to provide a predicted value Y.Type: GrantFiled: May 17, 2004Date of Patent: May 23, 2006Assignee: Pavilion Technologies, Inc.Inventors: Gregory D.

Patent number: 7027893Abstract: A tool changer comprising a master module and a tool module includes a rapid-connect communication bus between the master and tool modules. A unique tool identification number, along with other tool-related information, may be transmitted from the tool module to the master module within about 250 msec of the master and tool modules coupling together. The master module includes a robotic system communications network node connected to the rapid-connect communication bus, and operative to transmit data between the tool and the network via the communication bus. The need for a separate network node in the tool module is obviated, reducing cost and reducing the start-up time required to initialize such a network node upon connecting to a new tool. The rapid-connect communication bus may be a serial bus.Type: GrantFiled: August 25, 2003Date of Patent: April 11, 2006Assignee: ATI Industrial Automation, Inc.Inventors: Dwayne Perry, Richard Heavner

Patent number: 7002585Abstract: 3-D models of various types of objects such as a robot body, and a peripheral equipment, a machine, a part (workpiece), of the robot, are stored in an object library in advance. Dimension line data of an edge line of which dimension can be changed, and constraint condition for constraining coordinate positions of apexes which can be changed are also stored in the object library. A model having the shape corresponding to the shape of the object to be used is selected from the object library, and the dimension of the shape is set. The dimension of the selected model is modified so that the shape of the model corresponds to the shape of the actual object. Using the model of which dimension was adjusted, animation motion of the robot is formed on a display screen. With the above arrangement, it is possible to easily set and change object 3-D models relating to a robot motion.Type: GrantFiled: October 12, 2000Date of Patent: February 21, 2006Assignee: Fanuc LTDInventors: Atsushi Watanabe, Tetsuya Kosaka, Yoshiharu Nagatsuka

Patent number: 6999851Abstract: A robot apparatus and a motion controlling method for the robot apparatus wherein a reflex motion or the like can be performed at a high speed while decreasing the calculation amount of and the concentrated calculation load to a control apparatus. The robot has a control configuration having a hierarchical structure including a higher order central calculation section corresponding to the brain, reflex system control sections corresponding to the vertebra, and servo control systems and actuators corresponding to the muscles. From restrictions to the power consumption and so forth, there is a limitation to increase of the speed of a control cycle of the higher order central calculation section. External force acting upon the machine body is a disturbance input of a high frequency band, and a very high speed control system is required.Type: GrantFiled: August 28, 2003Date of Patent: February 14, 2006Assignee: Sony CorporationInventors: Keisuke Kato, Shinji Ishii
