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.
Claims17
A cleaning robot comprising:
- a floor-obstacle sensing module configured to emit a floor-sensing radio wave toward a floor and detect a floor-reflected radio wave reflected from a floor obstacle or the floor;
- and
- a controller configured to detect quality of a material of at least one of the floor obstacle or the floor, based on a waveform of the floor-reflected radio wave.
A cleaning robot comprising:
- a floor-obstacle sensing module configured to transmit a floor-sensing radio wave toward a floor, and detect a floor-reflected radio wave reflected from a floor obstacle or the floor;
- a front-obstacle sensing module configured to transmit a front-sensing radio wave toward a front of the main body and detect a front-reflected radio wave reflected from a front obstacle;
- and
- a controller configured to detect the floor obstacle based on the floor-reflected radio wave and detect the front obstacle based on the front-reflected radio wave.
