There are three basic technologies used in commercial systems to guide service robots: im‐ bedded guide wires, with guiding tape, and self‐guided robots. In the method with the embedded wire, an electrical conductor (wire) is placed in a small channel that is installed on the surface of industrial flooring. The channel is mostly 3‐12 mm wide and 13‐16 mm deep. After the wire is set, the channel is filled with cement to align the floor. The guide is connected to a generator that emits low frequency current‐voltage signal with a frequency in the zone of 1‐15 kHz. The mag‐ netic field is induced along the path which can be monitored with sensors on the leading plate of service robots, as we see in Fig. 5.
