The pickbar has an elongated body with a plurality of vacuum grippers spaced along the body each for gripping an individual solar cell of the solar cell string. A vacuum source applies a vacuum through the vacuum grippers to grip the solar cells and a controller connected to the robotic arm positioned the solar cell string gripped by the pickbar on a substrate. A pair of sensor assemblies mounted on the pickbar generates signals representing positions of portions of the solar cell string and features of the substrate. The controller responds to the signals for positioning the gripped solar cell string relative to the substrate.

  • Publication number: 20130256146
    Abstract: Provided are cleaning methods and systems to remove unintended metallic deposits from electroplating apparatuses using reverse current deplating techniques. Such cleaning involves positioning a cleaning (deplating) disk in an electroplating cup similar to a regular processed substrate. The front surface of the cleaning disk includes a corrosion resistant conductive material to form electrical connections to deposits on the cup's surfaces. The disk is sealed in the cup and submerged into a plating solution. A reverse current is then applied to the front conductive surface of the disk to initiate deplating of the deposits. Sealing compression in the cup may change during cleaning to cause different deformation of the lip seal and to form new electrical connections to the deposits. The proposed cleaning may be applied to remove deposits formed during electroplating of alloys, in particular, tin-silver alloys widely used for semiconductor and wafer level packaging.

  • Patent number: 8509951
    Abstract: The invention refers to a method for controlling the effector trajectory from a current state to a target state. First invariant control parameters of the trajectory are determined. The effector trajectory is then represented in a task description being void of the invariant control parameters. The effector trajectory is controlled on the basis of this task description. The invention further refers to a method for controlling the effector trajectory wherein the effector trajectory is calculated by mapping increments from a control parameter space on a configuration space. The dimensional difference between the configuration space and the control parameter space leaves redundant degrees of freedom of a Null space. The degrees of freedom of the Null space are increased using a task description being void of invariant control parameters.

  • Patent number: 8452443
    Abstract: An industrial robot system including a workcell including a load area and a process area. A detector detects when a human enters the load area. A manipulator is located in the workcell. At least one positioner is adapted to hold a workpiece and to change the orientation of the workpiece about at least one axis while the manipulator processes the workpiece. A station exchanger is movable about an axis and adapted to move, upon command, the manipulator or the positioner between the load and process area. Each of the axes is provided with a motor and a drive unit. An axis controller is adapted to switch between executing a first task in which the axes of the positioner and the station exchanger are commanded to a standstill, and a second task in which the axes of the positioner and the station exchanger are allowed to move.

  • Patent number: 8418830
    Abstract: At present, the removal the sticks from the mineral feeding lines, as a result of the mineral extraction, is carried out manually or using mechanical equipment, which means a loss of efficiency of the grinding and crushing system, high exposure to the risks associated to the removal of foreign elements of grinding material, this method does not guarantee problems from this cause in the subsequent stages in the grinding and crushing process. Due to the above, a robot system and method have been developed for the removal of sticks from the conveyor belts. The robotic system is composed mainly of an anthropomorphous robotic manipulator of at least 5 degrees of freedom, and a gripping mechanism which is supported by a vision system allowing, in a sequential and programmed way, to remove the sticks. In this regard, most of the problems associated to the safety of the personnel and the productivity of the current manual and/or mechanical process are eliminated.

    Abstract: In a method for controlling motion of a mechanical arm, the method moves the mechanical arm horizontally or vertically so that an image capturing device of the mechanism arm focuses on an object. The contours of the object are analyzed, and a central area of the object is established. By making the center of the image area of the image capturing device coincide with the center area of the object at least twice, the method records two positions of the mechanical arm, and calculates a total apparent displacement value of the object and a distance between the object and camera lens of the image capturing device according to the first position, the second position of the mechanical arm and the total apparent displacement value of the object. The method ensures accurate positioning of the mechanical arm.

  • Publication number: 20130085510
    Abstract: The systems and methods disclosed herein generally involve a robotically-assisted surgical system in which a platform for supporting a patient is physically and operatively coupled to a surgical robot and an associated controller. As a result, the position of the patient can be controlled remotely using the robot, and the controller can have an awareness of the position and orientation of the patient with respect to the operating room and with respect to various components of the robot. Such systems can thus maintain a fixed frame of reference between the patient and one or more end effectors of the surgical robot, eliminating the need for recalibration of the system due to patient movement.

  • Patent number: 8412376
    Abstract: A method is provided for distributing tension among tendons of a tendon-driven finger in a robotic system, wherein the finger characterized by n degrees of freedom and n+1 tendons. The method includes determining a maximum functional tension and a minimum functional tension of each tendon of the finger, and then using a controller to distribute tension among the tendons, such that each tendon is assigned a tension value less than the maximum functional tension and greater than or equal to the minimum functional tension. The method satisfies the minimum functional tension while minimizing the internal tension in the robotic system, and satisfies the maximum functional tension without introducing a coupled disturbance to the joint torques. A robotic system includes a robot having at least one tendon-driven finger characterized by n degrees of freedom and n+1 tendons, and a controller having an algorithm for controlling the tendons as set forth above.
