Benefits of technology

[0034]A cleaning robot according to another aspect of the present invention is capable of detecting the presence and position of an obstacle using impulse waves which are robust to external influences. Thus, an obstacle-sensing capability of the cleaning robot is hardly changed by a change in an external environment.

Problems solved by technology

While the cleaning robot cleans a space under a sofa, a bed, etc., the user would have difficulties in finding the cleaning robot.
Also, the user may have difficulties in controlling driving of the cleaning robot using a remote control to move the cleaning robot to a specific location.
Also, while the cleaning robot cleans a space to be cleaned while driving through the space, movement of the cleaning robot may be interrupted with an obstacle (such as furniture, a door sill, wire, etc.) located in a driving path of the cleaning robot.
However, when infrared light or ultrasonic waves are used, the precision of detecting the presence and position of an obstacle may be low due to the color of a space to be cleaned, light such as sunlight, external noise, temperature, etc.

Abstract

Provided is a cleaning robot including a main body; a driving unit configured to move the main body; a communication unit configured to establish wireless communication with a user terminal to which a manipulation command is input; and a controller configured to transmit a position detecting signal to the user terminal, and detect a position of the user terminal based on a time difference between the position detecting signal and a response signal transmitted from the user terminal.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation application of U.S. patent application Ser. No. 15 / 031,978 filed on May 12, 2016, which is a U.S. national stage application of International Application No. PCT / KR2014 / 010031 filed on Oct. 23, 2014 and claims the priority benefit of Korean Application Nos. 10-2013-0127940 and 10-2013-0127956 each filed on Oct. 25, 2013, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference in their entirety.BACKGROUND1. Field[0002]The present invention relates to a cleaning robot, and more particularly, to a cleaning robot capable of detecting the positions of a user and an obstacle.2. Description of the Related Art[0003]A cleaning robot is a device that automatically cleans a space to be cleaned by sucking foreign substances, such as dust, from a floor of the space while driving through the space without a user's manipulation. That is, the cleaning robot cleans a space to be...
