A method of correcting measurement errors in a measurement robot resulting from relative movements between an object to be measured and a measurement probe comprises the steps of detecting the accelerations at the probe, detecting the accelerations at or close to the object to be measured, calculating the correction data reproducing the relative movement from the measured accelerations and correcting the measured values recorded by the measurement robot with the correction data. The robot serves for determining shape and/or coordinates of an object to be measured, with a base unit, at least one movable measurement probe arranged on the base unit and a holding device arranged on the base unit for holding the object to be measured, wherein first acceleration are arranged on or close to the measurement probe, and second acceleration pickups are provided on the base unit, and an evaluation device is provided which calculates correction data from the measured data of the first and second acceleration pickups.
