Abstract: A distance measuring system includes: at least one emitter, which emits a frequency-variable scanning signal; at least one receiver; and an analysis unit for computing a distance to an object reflecting the scanning signal on the basis of a difference between the frequencies of the emitted and the received scanning signal. The rate of change of the frequency of the scanning signal in a first operating mode of the distance measuring system has a first finite value. The rate of change of the frequency in a second operating mode has a second finite value. The analysis unit is configured to compute a first distance on the basis of a frequency difference ascertained in the first operating mode, to compute a second distance on the basis of a frequency difference ascertained in the second operating mode, and to evaluate the correspondence between first and second computed distance.

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.
