摘要:
The invention relates to a method for correcting a manipulator-parameter, wherein a manipulator is controlled at least by means of a manipulator-parameter. A change in the manipulator-parameter is determined over time and a residual error in the positional precision of the manipulator is corrected using the specific change in the manipulator-parameter over time.

Ein erfindungsgemäßes Verfahren zur Kompensation einer kinematischen Abweichung, insbesondere einer Temperaturdrift, eines Manipulators, insbesondere eines Roboters (1), umfasst die Schritte: (S10) Anfahren verschiedener Posen des Manipulators; (S20) Erfassen einer Position (x, y, z, a, b, g) eines Manipulatorgliedes (2) mittels eine externen 3D-Positionserfassungseinrichtung (4) in der jeweiligen Pose; und (S30) Kompensieren der kinematischen Abweichung auf Basis der erfassten Position des Manipulatorgliedes.
摘要:
A controlling unit obtains an error in position and orientation of each joint of a robot. The controlling unit uses an error component in a driving direction of an actuator included in the error in position and orientation u i of the joint to obtain a first correction quantity, to obtain a residual error excluding the error component in the driving direction of the actuator from the error in position and orientation of the joint, and to obtain- an error in position and orientation of the end point of the robot based on the residual error of each joint. The controlling unit uses the error in position and orientation of the joint based on the error in position and orientation of the end point of the robot to obtain a second correction quantity Δq i , and uses the first correction quantity and the second correction quantity to correct a joint instruction value.

摘要:
The invention relates to a method for controlling a manipulator. Said method consisting of providing a temperature-dependent calibration, using said calibration a correction parameter set is calculated which is based on determined reference point residual drift values. Subsequently, the manipulator is controlled by taking into account the correction parameter set.
