Publication number: 20090268010Abstract: An illumination channel, a stereoscopic optical channel and another optical channel are held and positioned by a robotic surgical system. A first capture unit captures a stereoscopic visible image from the first light from the stereoscopic optical channel while a second capture unit captures a fluorescence image from the second light from the other optical channel. An intelligent image processing system receives the captured stereoscopic visible image and the captured fluorescence image and generates a stereoscopic pair of fluorescence images. An augmented stereoscopic display system outputs a real-time stereoscopic image comprising a three-dimensional presentation of a blend of the stereoscopic visible image and the stereoscopic pair of fluorescence images.Type: ApplicationFiled: June 30, 2008Publication date: October 29, 2009Applicant: Intuitive Surgical, Inc.Inventors: Wenyi Zhao, Christopher J.

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: 7603927Abstract: An automatic manipulator, such as a multiaxial industrial robot, with a carrying component structure (support structure) for transmitting forces between individual members of the automatic manipulator. The entire support structure is formed from a material that is resistant with respect to external effects, such as moisture or the like. The material of the support structure may be, in particular, a material that is suitable for use in contact with foods, such as stainless steel, so that the automatic manipulator according to the present invention can be used reliably and without additional costly protective measures in environments in which there is a risk for contamination, such as in the food industry.Type: GrantFiled: October 28, 2004Date of Patent: October 20, 2009Assignee: KUKA Roboter GmbHInventors: Joachim Markert, Günther Merk

Publication number: 20090248040Abstract: A coupler to provide controller motion from a robotic manipulator includes a pin having a tip with a spherical bearing surface and a plate supported on the spherical bearing surface of the pin with two degrees of rotational freedom about the center of the spherical bearing surface. The plate has a back surface and an opposing driving surface that bears against a first surface of an inner gimbal of a gimbal assembly of a driven device. The plate includes a pin receiving portion that extends outwardly from the driving surface and away from the back surface. The pin receiving portion includes a spherical receiving surface to receive the spherical bearing surface of the pin. The spherical bearing surface is located at a distance above the driving surface such that the center of the spherical bearing surface coincides with an intersection of the gimbal assembly axes of the driven device.Type: ApplicationFiled: March 31, 2008Publication date: October 1, 2009Applicant: INTUITIVE SURGICAL, INC.Inventors: Thomas G.

Patent number: 7590468Abstract: A robot system can grasp and take out one of a plurality of workpieces placed in a basket-like container by a hand mounted at the forward end of a robot arm. The workpiece is detected by a visual sensor, and the robot is controlled depending on a position and an orientation of the workpiece. When a problem such as interference or the like occurs, information relating to the problem is stored in a robot control unit or a visual sensor control unit. Information relating to the problem includes a predetermined amount of the latest data retrospectively traced from the time point of problem occurrence, a position which the robot has reached, the target position data, the content of the process executed by the visual sensor, and the detection result. When the problem is reproduced, these data are used to simulate the situation at the time of problem occurrence by using simulation unit. The situation at the time of problem occurrence can also be reproduced by using the actual robot without using the simulation unit.Type: GrantFiled: September 29, 2004Date of Patent: September 15, 2009Assignee: Fanuc LtdInventors: Atsushi Watanabe, Kazunori Ban, Ichiro Kanno

Publication number: 20090204259Abstract: A control method and system for controlling a hydraulically actuated mechanical arm to perform a task, the mechanical arm optionally being a hydraulically actuated excavator arm. The method can include determining a dynamic model of the motion of the hydraulic arm for each hydraulic arm link by relating the input signal vector for each respective link to the output signal vector for the same link. Also the method can include determining an error signal for each link as the weighted sum of the differences between a measured position and a reference position and between the time derivatives of the measured position and the time derivatives of the reference position for each respective link. The weights used in the determination of the error signal can be determined from the constant coefficients of the dynamic model. The error signal can be applied in a closed negative feedback control loop to diminish or eliminate the error signal for each respective link.Type: ApplicationFiled: August 7, 2008Publication date: August 13, 2009Inventor: George DANKO
