Virtual wall system of self-walking apparatus

Abstract

The disclosed virtual wall system for a self-walk device comprises: a self-walk device with a steering device, a connected controller, at least a signal emitter, and a receiver; at least a virtual wall generator with a signal receiver, an audio emitter, a signal controller. Wherein, then walking, the signal receiver receives signal, the controller controls the audio generator to produce audio, the audio receiver receives the signal, and the controller forces the device steering.

Description

technical field [0001] The present invention is related to the control of the self-propelled device, in particular to a virtual wall system of the self-propelled device. Background technique [0002] Existing self-propelled devices, such as self-propelled robots, or self-propelled vehicles, or self-propelled vacuum cleaners, etc., all determine the direction, speed and distance of the advance according to the pre-input route, or by means of image recognition, and , such as the technology disclosed in US Patent Early Publication No. US 2004 / 0,111,184, which mainly discloses a technology in which a self-propelled vacuum cleaner uses light beams as a virtual wall. The self-propelled vacuum cleaner has a light source receiver to receive the light beam. When the self-propelled vacuum cleaner travels to receive the light beam, it sends a turning signal to reach the limit of the light beam that does not exceed the light source transmitter. position, which in turn has the effect of...

AI Technical Summary

Problems solved by technology

[0003] However, in the aforementioned prior art, during operation, the light source transmitter must continuously emit light to ensure that the light source receiver on the self-propelled vacuum cleaner will continue to use power when the self-propelled vacuum cleaner passes by. If the light source transmitter uses battery power, the battery will be consumed quickly, and if the external mains power is used, there will be problems such as forgetting to pull out the plug or dragging the wire to the floor, which may cause obstacles, etc.
