Document Type and Number:
Japanese Patent JP2019185411
Kind Code:
A
Abstract:
To efficiently return an autonomous type travel cleaner (mobile object) to a base station.SOLUTION: An autonomous type travel cleaner comprises: a receiving part capable of detecting a return signal; an obstacle sensor for detecting obstacles; a control part capable of storing a point where the return signal is received; and a control part capable of storing a point detected by the obstacle sensor. The autonomous type travel cleaner is driven such as to avoid obstacle detected points by an advancing step of calculating a direction to a return signal reception point relative to a current position of the cleaner and advancing in that direction when the obstacle sensor detects an obstacle during advancing based on the return signal.SELECTED DRAWING: Figure 13
