<p>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.</p> |
