Abstract

A self-moving robot system may comprise a signal generating device configured to generate a preset signal; a signal detecting device, configured to detect the preset signal and generate a detection result; a signal line configured to radiate or/and receive the preset signal; and a control unit disposed on a self-moving robot, wherein the control unit receives the detection result and controls the self-moving robot to move according to the detection result; one end of the signal line is connected to the signal generating device or/and the signal detecting device; the signal line unidirectionally extends from the end, and the signal line does not constitute a circuitry loop. The system can realize judging a working area and/or guiding returning of the self-moving robot by a non-closed signal line, to thereby simplify arrangement of the border line or guide line, and improve the user experience.

Dependent claims

A self-moving robot system, comprising:

a self-moving robot, automatically moving and automatically working in a working area;
a signal line, comprising an antenna, defining a border of the working area or/and defining a returning path of the self-moving robot;
a signal generating device, generating a preset signal suitable to be radiated to a free space in a radio wave manner,
a signal detecting device, detecting the preset signal existing in the free space in the radio wave manner, thereby generating a detection result;
and
a control unit, disposed in the self-moving robot to receive the detection result and controlling the self-moving robot to move according to the detection result,
wherein the self-moving robot system is characterized in that one end of the signal line is connected to the signal generating device or/and the signal detecting device and the signal line is configured to radiate the preset signal to the free space in the radio wave manner or receive the preset signal existing in the free space in the radio wave manner;
and
the signal line unidirectionally extends from the one end to constitute a circuitry open circuit.
