Problems solved by technology

[0004] However, the design of the signal receiving and transmitting circuits of traditional automatic walking devices and charging stations is too complicated, and the positioning calculation is time-consuming, and has problems such as large power consumption and high cost.
In addition, traditional self-propelled devices perform positioning based on the absolute value of the strength of the received guidance signal, which is susceptible to misjudgment due to the attenuation of the guidance signal after the charging station has been used for a long time

Abstract

The invention provides a control method for an autonomous mobile robot. The method of an autonomous mobile robot comprises: receiving a dock signal and executing a control program according to the dock signal. The control program includes detecting a first guiding signal, a second guiding signal and a third guiding signal transmitted by the charging station via the first sensing unit, the second sensing unit and the third sensing unit, sensing a measured distance between the autonomous mobile robot and the charging station when the second guiding signal is detected by the second sensing unit, and the autonomous mobile robot moves toward the charging station or away from the charging station according to the measured distance and a first threshold, and re-executing the control program.

Description

technical field [0001] The invention relates to automatic control technology, in particular to an automatic walking device and a control method thereof. Background technique [0002] With the progress and development of automation control technology, many automation equipment have been widely used in various work or life of human beings. However, the handling robots used to carry heavy objects in factories, the detection robots used for outer space exploration, the security robots used for patrolling, or the cleaning robots used for environmental cleaning, etc., have all played a very important role in modern times. Among the many types of these automation equipments, automatic walking devices that can walk automatically to perform preset tasks are very common. [0003] Since the power stored in the automatic running device is limited, the automatic running device needs to return to the charging station for charging operation through the guidance signal emitted by the charg...
