Abstract: The present invention relates to a method for monitoring the operation of a robot, in particular an articulated arm robot having, for example, 6 axes, in a protective field, wherein the protective field has an outer boundary, wherein

a respective space occupied by the robot is determined for different robot positions,
the space occupied by the robot in the respective robot position is removed from the protective field, wherein an inner boundary of the protective field is created and/or changed by removing the occupied space.

Abstract: A method and a safety system for localizing at least two objects has a control and evaluation unit, and at least one radio location system. The radio location system has at least three arranged radio stations, wherein at least two respective radio transponders are arranged at the objects. The two radio transponders are arranged spaced apart from one another. Position data of the radio transponders and thus position data of the objects can be determined by means of the radio location system, and the position data can be transmitted from the radio station of the radio location system to the control and evaluation unit and/or the position data can be transmitted from the radio transponder to the control and evaluation unit. The control and evaluation unit is configured to cyclically detect and compare the position data of the radio transponders.
