Embodiment Construction

[0019] figure 1 is a perspective view showing a robot cleaner according to the present invention with the upper cover removed. figure 2 is a block diagram showing a robotic cleaning system according to the present invention.

[0020] refer to figure 1 and figure 2 , a robot cleaner 10 includes a suction unit 11 , a sensor 12 , a front camera 13 , an upper camera 14 , a driving unit 15 , a memory 16 , a transmitting / receiving unit 17 , and a controller 18 . Serial number 19 represents a battery.

[0021] The suction unit 11 is installed in a main body 10a, and sucks air through a facing cleaning surface to collect dust. The suction unit 11 can be constructed by various methods that are about to be known. For example, the suction unit 11 includes a suction motor (not shown) and a dust collection chamber for collecting dust. Driven by the motor, the dust is sucked through a suction port or a suction pipe positioned at the cleaning face.

[0022] The sensor 12 includes, an...

Abstract

The machine (10) has a forward viewing camera and infrared sensors to avoid ground objects and a vertically viewing camera (14) with a fisheye lens which interprets data from ceiling (33) mounted transmitters (31) to guide it over the cleaning path.

Description

technical field [0001] The present invention relates to a robot cleaner, a robot cleaning system, and a method of controlling the robot cleaner, in particular, a robot cleaner and a robot cleaner capable of identifying the current position of the robot by using images captured while the robot is moving. A robotic cleaner system, and a method for location recognition. Background technique [0002] A typical robot cleaner uses an ultrasonic sensor installed in its body to determine the area to be cleaned and Plan a cleaning route for the area the cleaner will clean. Then, the robot cleaner calculates its movement distance and current position based on a signal detected by a sensor that detects the number of revolutions per minute and the angle of rotation of a wheel of the robot cleaner. The robotic cleaner drives its wheels along a programmed route. However, in such a position recognition method, there is an error between the calculated travel distance and the current posi...
