A building monitoring system includes a first sensor configured to detect a first condition in the space, a second sensor configured to detect a second condition in the space, and a robotic sentinel. The robotic sentinel includes a memory for storing one or more rules each configured to identify an alert condition for the space based on the first and/or second conditions in the space, a communications module configured to communicate with a remote device over a network, and a controller operatively coupled to the sensors, the memory, and the communications module. The controller is configured to apply the one or more rules to the first and second detected conditions in the space to identify one or more alert conditions and determine what action is required by the robotic sentinel, and if action is required, command the robotic sentinel to travel to a location of the alert condition.

An electronic device is provided. The electronic device includes a memory and a processor configured to move the electronic device, obtain an image and location of the external electronic device, identify the external electronic device based on the obtained image, transmit the plurality of control commands to the identified external electronic device, monitor a response of the external electronic device, store an identifier of a first control command set and the location of the external electronic device, wherein the first control command is based on the monitoring, and the first control command set includes the first control command that performs a pre-specified first operation, receive a first input, move the electronic device based on the received first input and the location, and transmit the first control command to the external electronic device based on the received first input and the identifier of the first control command set.

A robot system can include a main body; a manipulator installed on the main body; a sensor configured to detect an object approaching a restricted region including the manipulator; a camera configured to monitor the restricted region and the object approaching the restricted region; a storage configured to store a material for an operation of the manipulator, the storage including an inlet for receiving the material; a remaining amount sensor configured to detect an amount of the material remaining in the storage; and a controller configured to change the restricted region based on at least one of a result of detection of the remaining amount sensor and image information of the camera, and in response to the sensor detecting that the object is within the restricted region, stop manipulation of the manipulator.

Disclosed are a robot system and an operation method thereof. The robot system includes a central controller, a robot configured to communication with the central controller and capable of autonomous driving, and a first sensing module configured to communicate with the central controller, to be mounted inside an elevator, and configured to measure an electric power of a communication radio wave emitted by a mobile communication device inside the elevator. The robot may transmit or receive a wireless signal on a mobile communication network established according to 5G communication.

A movable body is configured to receive a package at a first location and wait for a recipient at a second location that is different from the first location. The movable body includes: a body configured to perform autonomous driving; a storage box attached to the body, the storage box being configured to temporarily store the package; and a controller configured to move the body from the first location to the second location.

Disclosed is a method of controlling a robot, comprising: switching to a surrounding environment concentration mode according to a sound of surrounding environment in a display off mode; searching a user in the surrounding environment concentration mode and switching to a user concentration mode when the user is searched; switching to a user conversation mode from the user concentration mode according to a sound received from the user; and entering the display off mode again after passing through a play alone mode, when the user is not searched in the surrounding environment concentration mode. Accordingly, the robot can operate in an optimal mode according to the change of the surrounding environment by setting various modes of the robot.

An artificial intelligence (AI) cleaner according to an embodiment of the present invention may include a memory, a movement detect sensor, a driving unit configured to allow the AI cleaner to be moved, and a processor configured to control the movement sensor to sense a movement of the AI cleaner by a user and acquire a position to which the AI cleaner has moved while the AI cleaner operates at a first cleaning mode and control the driving unit to allow the AI cleaner to clean a priority cleaning area corresponding to the position at a second cleaning mode.

A robot in a location interacts with a user. The robot includes a camera, an image recognition processor, a microphone and a loudspeaker, a voice assistant, and a wireless transceiver. The robot moves around and creates a model of the location, and recognizes changes. It recognizes objects of interest, beings, and situations. The robot monitors the user and recognizes body language and gesture commands, as well as voice commands. The robot communicates with the user, the TV, and other devices. It may include environment sensors and health status sensors. It acts as a user companion by answering queries, executing commands, and issuing reminders. It may monitor to determine if the user is well. The robot may monitor objects of interest, their placement and their status. When necessary, it communicates with the user.

Disclosed herein is a robot including an output interface including at least one of a display or a speaker, and a processor configured to acquire output data of a predetermined playback time point of content output via the robot or an external device, recognize a first emotion corresponding to the acquired output data, and control the output interface to output an expression based on the recognized first emotion.

A method for controlling a robot is provided. The method includes the steps of: acquiring information on a sound associated with a robot call in a serving place; determining a call target robot associated with the sound, among a plurality of robots in the serving place, on the basis of the acquired information; and providing feedback associated with the sound by the call target robot.
