20110203402 | PROCESS TURNING DISC, A ROBOT ARM COMPRISING A PROCESS TURNING DISC, A ROBOT AND A USE OF A PROCESS TURNING DISC - A process turning disc connectable to an output shaft of a motor configured to rotate the process turning disc about a first center axis of the process turning disc. The process turning disc being configured to guide a cable or hose. A first flange is connectable to an end part of a robot arm. A second flange is connectable to a tool element. The flanges are spaced apart from each other by an intermediate connecting member. The connecting member is connected to the flanges. The connecting member provides a passage between the flanges. The passage is configured to receive and guide the cable/hose. The passage has an inlet side for the cable/hose and an outlet side for the cable/hose. A robot arm including the process turning disc, a robot including the robot arm and a method that utilizes the process turning disc. | 08-25-2011 |

20110142534 | METHOD FOR MANUFACTURING A JOINT AND A JOINT OBTAINABLE BY THE METHOD - A method for manufacturing a joint. A ball is mounted on a pin. Spherical surfaces on at least two socket parts are machined. Grinding paste is applied on the ball and/or on the surfaces of the socket parts. The pin is connected to an equipment that rotates the ball. The ball is assembled between the socket parts. A pressure is applied between the socket parts and the ball. The ball is rotated and tilted over the working range of the joint. The ball and the socket parts are cleaned from the grinding paste. The joint is assembled by mounting the socket parts on a ball. A robot obtainable with the method. | 06-16-2011 |
20110127935 | Drive unit - The present invention relates to a drive unit for at least one electric motor. The drive unit comprises: a control power supply (+18V) for supplying the drive unit with control power, a power source ( | 06-02-2011 |
20110106308 | METHOD AND A DEVICE FOR OPTIMIZING A PROGRAMMED MOVEMENT PATH FOR AN INDUSTRIAL ROBOT - A device and method for optimizing a programmed movement path for an industrial robot holding a tool to carry out work along the path during a work cycle. The movement path includes information on positions and orientations for the tool at a plurality of target points on the movement path. The method includes for at least one of the target points: receiving a tolerance interval for the orientation of the tool in the target point, determining movements of the robot between the target point and one or more of the other target points on the path for a plurality of different tool orientations within the tolerance interval, selecting one of the different tool orientations as the tool orientation for the target point based on the determined movements of the robot and with regard to minimizing cycle time, and generating a robot program based on the selected orientation of the tool at the target point. | 05-05-2011 |
20110046782 | A METHOD AND SYSTEM FOR DETERMINING THE RELATION BETWEEN A ROBOT COORDINATE SYSTEM AND A LOCAL COORDINATE SYSTEM LOCATED IN THE WORKING RANGE OF THE ROBOT - The present invention relates to a method and a system for determining the relation between a local coordinate system located in the working range of an industrial robot ( | 02-24-2011 |
20100274385 | CONTROL SYSTEM FOR CONTROLLING AN INDUSTRIAL ROBOT - A control system for controlling at least one industrial robot, wherein the control system comprises a plurality of software modules ( | 10-28-2010 |
20100231158 | SERVER CONTROLLER AND A METHOD FOR CONTROLLING A PLURALITY OF MOTORS - Servo controller for controlling a plurality of motors including a master motor and a slave motor cooperatively driving a movable member. The servo controller is configured to control the master motor and the slave motor based on position references for the master motor. The servo controller includes a master speed controller configured to calculate a reference torque for the master motor based on speed errors for the master motor. The slave speed controller is configured to calculate reference torques for the slave motor based on speed errors for the slave motor. Each of the reference torques includes a proportional torque part and an integral torque part. The servo controller is configured to calculate each of the integral torque parts based on the speed errors of the master motor and the speed errors of the slave motor, such that the torques due to the integral torque parts will be distributed equally between the master and slave motors or according to a predefined ratio. | 09-16-2010 |
20100185315 | ROBOT TOOL, ROBOT SYSTEM AND METHOD FOR MACHINING WORKPIECES - A robot tool for machining workpieces, includes a connecting element for connection to a robot. A cutting blade is maintained in a predetermined position by a retaining element, the retaining element being connectible to the robot by a connecting element. | 07-22-2010 |
20100157633 | REDUNDANT CURRENT VALVE CONTROL IN A HIGH VOLTAGE POWER TRANSMISSION SYSTEM - A method and device for providing redundant control of a controllable current valve in a converter of a power transmission system. A first converter control unit sends a first valve control signal. A first active/standby indicator is associated with the first converter. A second converter control unit sends a second valve control signal. A second active/standby indicator is associated with the second converter control unit. The device also includes a valve control unit. An active/standby indicator indicates if a corresponding converter control unit is active or standby. Only one indicator indicates an active unit at a given point in time. The valve control unit receives the active/standby indicators and valve control signals, selects a valve control signal to be applied if the corresponding active/standby indicator indicates an active converter control unit and controls the current valve using the selected valve control signal. | 06-24-2010 |
