Abstract

A method for controlling a robot includes the steps of: deciding whether there is a non-permanent object in a vicinity of the robot; if there is a non-permanent object, deciding whether the object qualifies for extended protection or not; and defining a safety zone around the object which the robot must not enter or in which a maximum allowed speed of the robot is less than outside the safety zone. The safety zone extends to a greater distance from the object if the object qualifies for extended protection than if it does not.
