Abstract
The present disclosure relates to a cleaning robot and a method of controlling the same, and more particularly, to a cleaning robot that changes a moving path by detecting an obstacle through a change in permittivity detected while driving about a cleaning space, and a method of controlling the same. The cleaning robot comprises a main body; a driver configured to move the main body; an obstacle detector including an electrode plate provided on the bottom of the main body and a touch IC configured to detect a change in capacitance detected by the electrode plate and; and a controller configured to determine the obstacle based on a signal transmitted by the obstacle detector, and to control the driver.
Claims14
A cleaning robot comprising:
- a main body;
- a driver configured to move the main body;
- an obstacle detector including an electrode plate provided on a bottom of the main body and a touch integrated circuit (IC) configured to detect a change in capacitance detected by the electrode plate;
- a storage configured to store an average value of the capacitance detected by the touch IC;
- and
- a controller configured to:
- calculate a difference value between a measured value of the capacitance detected by the touch IC and the stored average value of the capacitance while the main body drives, and
- determine an obstacle based on the difference value, and to control the driver.
A method of controlling a cleaning robot including an electrode plate provided on a main body and a touch integrated circuit (IC) configured to detect a change in capacitance detected by the electrode plate, the method comprising:
- storing, by a storage, an average value of the change in the capacitance detected by the touch IC in a cleaning space in which the cleaning robot drives;
- calculate, by a controller, a difference value between the stored average value with a measured value detected by the touch IC while the main body is driving;
- and
- controlling, by the controller, a driving direction of the main body based on the difference value.
