Description

Security robot and its control method {SECURITY ROBOT AND METHOD FOR CONTROLLING SECURITY ROBOT}

The present invention relates to a security robot and a method for controlling the security robot.

In general, the security system detects a signal from a sensor that can detect external intrusion inside a specific area, such as an office or a general home, and sends a warning signal to a security company or police box that acts as a security agent. The security personnel are dispatched.

Such a security system may not only transmit an alarm signal due to a malfunction of the sensor, but also require a manager to directly check the crime prevention area even after the alarm signal is transmitted, thus causing a problem in confirming a crime. Therefore, the security system can apply the robot within a specific area, so that the verification procedure can be performed before the alarm signal is transmitted to the outside.

However, the robot can only operate if it receives a command from a particular device. In other words, it can be seen that it is very difficult for a robot to have the required level of cognitive ability to perform security.

The technical problem to be achieved by the present invention is to provide a security robot and its control method capable of judging like a human being and acting and reacting autonomously.

According to a feature of the present invention for achieving the above object, when the security system requests the security robot to confirm whether an intrusion occurred in the security area, the method for controlling the security robot is

Collecting the environment change information corresponding to whether the information is changed, and controlling the operation of each engine of the security robot based on at least one of the environment change information, a result of determining whether an intrusion has occurred or whether an intrusion has been incorrectly recognized.

According to another aspect of the invention, the security robot that works in conjunction with the security system that is responsible for the security of the security area

According to an embodiment of the present invention, the security robot can make an optimal judgment by accumulating and statistically collecting specific data, such as a human being accumulating experience, thinking and judging.

According to an embodiment of the present invention, the method for controlling the security robot by allowing the security robot and the security system to operate in conjunction, it is possible to allow the security robot to determine the task itself and to operate autonomously.
