Abstract
Disclosed is a mobile robot. The mobile robot may include a body and a controller. The mobile robot may execute an artificial intelligence (AI) algorithm and/or a machine learning algorithm, and may perform communication with other electronic devices in a 5G communication environment. Accordingly, user convenience can be significantly improved.
Claims18
A mobile robot, comprising:
- a body including a storage space;
- a motor configured to drive at least one of a plurality of wheels or a plurality of legs to move the body;
- and
- a controller configured to:
- set a security zone based on a location of the body,
- wherein the body is at a center of the set security zone,
- adjust a range of the security zone based on a predetermined condition, and
- determine a risk response level based on a zone occupation time and a movement of a target that has entered the security zone,
- wherein the controller is configured to control the motor such that the mobile robot moves faster than an approaching speed of the target in response to the risk response level being equal to or greater than a particular risk response level while the mobile robot is moving to a destination,
- wherein the controller divides the security zone into a plurality of partial security zones of respective distances from the body, and sets security levels of the plurality of partial security zones such that one of the partial security zones that is relatively closer to the body has a higher security level than another one of the partial security zones that is relatively further from the body,
- wherein the controller is configured to determine a suspicious target by using different criteria in each of the plurality of partial security zones, and
- wherein the predetermined condition includes at least one of time at which the mobile robot moves, whether the mobile robot is in a dangerous area, a floating population of a place where the mobile robot is located, or another condition set in advance by a user.

A method for operating a mobile robot, comprising:
- receiving an article in a storage space of a body of the mobile robot;
- while the mobile robot is moving to a destination or after the mobile robot arrives at the destination, setting, by a controller of the mobile robot, a security zone based on a location of the body of the mobile robot and adjusting a range of the security zone based on a predetermined condition;
- wherein the body is at a center of the set security zone,
- monitoring, by the controller of the mobile robot, a zone occupation time and a movement of a target that has entered the security zone;
- and
- determining, by the controller of the mobile robot, a risk response level based on the zone occupation time and the movement of the target,
- wherein the mobile robot further includes a motor configured to drive at least one of a plurality of wheels or a plurality of legs to move the body of the mobile robot, and the method further comprises:
- controlling, by the controller, the motor such that the mobile robot moves faster than an approaching speed of the target in response to the risk response level being equal to or greater than a particular risk response level while the mobile robot is moving to a destination;
- dividing, by the controller, the security zone into a plurality of partial security zones of respective distances from the body of the mobile robot, and setting, by the controller, security levels of the plurality of partial security zones such that one of the partial security zones that is relatively closer to the body of the mobile robot has a higher security level than another one of the partial security zones that is relatively further from the body of the mobile robot;
- and
- determining, by the controller, a suspicious target by using different criteria in each of the plurality of partial security zones,
- wherein the predetermined condition includes at least one of a time at which the mobile robot moves, whether the mobile robot is in a dangerous area, a floating population of a place where the mobile robot is located, or another condition set in advance by a user.
