Abstract
A method performed by a control node for handling communication with a robot device. The control node determines a distance from a planned trajectory and/or path, and a distance from a boundary surface, which distances are related to a command message received from a robot device, wherein the boundary surface is associated to an accuracy requirement. The control node further measures a performance of the trajectory based on the determined distance from the planned trajectory and/or path and from the boundary surface. The control node further evaluates an effect of the measured performance for the robot device.
