摘要:
The present invention relates to a dual arm robot comprising a body (1), a first arm (2) attached to the body in a first attachment point (3), a second arm (5) attached to the body in a second attachment point (6), and a controller (10) adapted to control the motions of the arms based on desired positions of the arms. The controller comprises a position correction module (12) for correcting the position of the second arm due to the position and movements of the first arm, and the position correction module is adapted to determine an elastic deformation in the second attachment point based on the force acting on the first attachment point and an elastic model of the body, to determine the change of the position of the second arm based on the determined elastic deformation in the second attachment point, and to correct the position of the second arm based on the determined change of the position of the second arm.
摘要:
A method for detecting condition changes in a robot system, wherein said method comprises a logging of work cycle representative signals at a first and at a second occasion, synchronizing said representative signals, and comparing said synchronized signals to determine if any condition changes have occurred between said first and second occasions.
摘要:
A method and an apparatus for detecting condition changes in a robot system. The method comprises the steps of: logging a work cycle representative signal at a first and a second occasion, logging, synchronously with said logging of the work cycle representative signal, a reference signal associated with work cycles at said first and second occasions, selecting said reference signal from signals having the following characteristics: a signal influenced by the path performed by the robot, a signal calculated by the robot system, and a signal that is identical at both said occasions if a manipulator of the robot performs a movement along exactly the same path at the first and second occasions, synchronizing said representative signals by means of said logged reference signals, and comparing said synchronized signals to determine if any condition changes have occurred between said first and second occasions.

The invention relates to a hand-held control device (12) for an industrial robot (10) comprising a manual input unit (22) for controlling the movement of the robot such that the movement of the robot corresponds to the movement of the input unit, wherein a first coordinate system (X 1 ,Y 1 ,Z 1 ) is defined relative to the control device such that it follows the movement of the control device, and a second coordinate system (X 2 , Y 2 , Z 2 ) is defined fixed to the robot, and the movements of the manual input unit are measured in the first coordinate system. The device further comprises a determining unit including a sensor (24) for determining the relative orientation between the first and the second coordinate system, and a calculating unit adapted to calculate the transformation between the first and second coordinate system based on the relative orientation between the coordinate systems, and to transform the movements of the manual input unit into corresponding movements in the second coordinate system based on said calculated transformation.
