CONTROL DURING AND METHOD OF MOVING PATH

‍ How to control the movement path of a robot vacuum cleaner in real time

This technology relates to a travel path control device and method, and relates to a travel path control device and method that can be applied to moving objects such as airplanes and automobiles.

Robot vacuum cleaners using existing infrared sensors or ultrasonic sensors have the problem that it is difficult to control the path of movement until an obstacle is detected, and if there is a space between the obstacles, they cannot be prevented from entering it, and it is often impossible to get out after entering that space. Therefore, this technology proposes a travel path control method that can control the movement path of an object that performs autonomous driving in real time.

This technology can be applied to moving objects such as robots and vacuum cleaners because it can control the direction of travel so that the moving object can enter in a direction perpendicular to the boundary line located at the front, return when it leaves the moving area, and control the movement path in real time.

Key features:

• Receives signals from multiple signal generators located on area boundaries
• Measure the object and the first signal generator using the signal received from the generator
• Determine the direction of movement of an object using the change value of the distance difference (differential) between the first signal generator and the second signal generator over a predetermined period of time
• Includes a second processing unit that determines whether an object has moved outside the boundary line using the change value of the distance sum (sum) between the first signal generator and the second signal generator
