A 3D sensor for monitoring a monitored zone is provided, wherein the 3D sensor has at least one light receiver for generating a received signal from received light from the monitored zone and has a control and evaluation unit that is configured to detect objects in the monitored zone by evaluating the received signal and to determine the shortest distance of the detected objects from at least one reference volume, and to read at least one distance calculated in advance from the reference value from a memory for the determination of the respective shortest distance of a detected object.

A method for controlling an industrial robot are disclosed, wherein the method is performed by a robot controller system, the robot controller system includes a local part connected to an industrial robot and a remote cloud part connectable to the local part. The local part includes a first real-time partition and a second non-real-time partition, and the method includes the steps of: storing a local cache of a complete file system of the robot controller system in the second non-real-time partition; storing the complete file system in the remote cloud part; and controlling the industrial robot in real time from the first real-time partition.
