Cleaning at home during housework is a relatively laborious task compared to other household chores, even if you use a vacuum cleaner to carry it around.

Therefore, the robot cleaner developed to solve this problem can automatically clean the area to be cleaned by inhaling foreign substances such as dust from the floor surface while traveling by itself in the area to be cleaned without the user's manipulation.

For the robot cleaner, research and development of a cleaning robot that performs cleaning while autonomously moving by using a remote controller (hereinafter referred to as a 'remote controller') is given. Research on mobile robots that have a complex function of cleaning robots plus home disaster prevention functions is ongoing.

Since the conventional robot cleaner does not have a function of detecting the shape of the cleaning area, cleaning is performed by using a sensor that detects an obstacle regardless of the shape of the cleaning area, or while driving the cleaning area according to the data previously input by the user. Cleaning will be performed.

When the sensor is used in the above, the robot cleaner determines the distance to the obstacles such as furniture, office supplies, and walls installed in the cleaning area by the sensor, and drives the moving means such as wheels provided in the robot cleaner, thereby changing its direction. Clean the cleaning area.

Therefore, the robot cleaner is more likely to repeatedly clean the already cleaned place, and the robot cleaner takes a long time to clean the cleaning area. In addition, since the outside of the robot cleaner cannot check the cleaning state, it is not possible to determine whether the cleaning is performed correctly.

In particular, since the conventional cleaning robot is to be cleaned through a basic algorithm built into the robot itself during production of the product, there is a blind spot where the cleaning time is excessively consumed or the cleaning is not performed.

The cleaning robot used for the conventional homenet sends a basic operation command for cleaning the command from the server centered on the homenet server. The cleaning robot operates according to the command and the cleaning situation is fed back to the homenet server so that the consumer of the homenet server It is configured to look at the display device to know the situation.
