A method of operating a robot

The invention relates to a method of operating a robot comprising the steps of: - detecting the spatial position and / or position of at least one limiting structure (20, 22), which causes a kinematic boundary of the working space (16), which is accessible by an instrument (12) which is connected to a robot arm (10) of the telemanipulation robot . - step-retention illustrating the achievable working space (16) to a by the instrument (12) to be manipulated object (14) such that a change in position and / or position of the boundary structure (20, 22) in real time to a change of the obtainable working space shown (16) leads.
