A robot service system including a robot including least one manipulator and a controller controlling the motion of the manipulator. A remote service center includes an analyzing computer, and a communication line between the robot controller and the remote service center. A monitoring component is configured to monitor the current operation of the controller and the current motions of the manipulator, and to transmit information on the current operation of the controller and the current motions of the manipulator to the remote service center. The analyzing computer is configured, upon request, to calculate new maximum permissible performance parameters for the robot based on the received information and to transmit the new maximum permissible performance parameters to the robot controller. The analyzing computer is further configured to calculate one or more monitoring parameter, and the monitoring component is further configured to supervise that the robot is not run outside allowed limits based on the monitoring parameters.
