A serving robot includes a camera to obtain image data including at least one of a facial expression or a gesture, which is associated with food, of a customer, a microphone to obtain voice data including voice of the customer, which is associated with the food and a processor to obtain customer reaction data including at least one of the image data or the voice data, through at least one of the camera or the microphone, estimate a reaction of the customer to the food, from the obtained customer reaction data, and generate or update customer management information corresponding to the customer based on the estimated reaction. The robot estimates the reaction the customer from the customer reaction data through the learning model based on artificial intelligence.

Proposed is a method for determining, by a movable robot, a position of a speaker, wherein the movable robot includes first to fourth microphones installed at four vertexes of a quadrangle of a horizontal cross section of the robot respectively, wherein the method includes: receiving a wake-up voice through first and third microphones disposed respectively at first and third vertices in a diagonal direction; obtaining a first reference value of the first microphone and a second reference value of the third microphone based on the received wake-up voice; comparing the obtained first and second reference values to select the first microphone; selecting a second microphone disposed at a second vertex, wherein the first and second microphones are on a front side of the quadrangle; calculating a sound source localization (SSL) value based on the selected first and second microphones; and tracking a position of the speaker based on the SSL value.

A controller includes at least one memory, and at least one processor. The at least one processor is configured to acquire speech, recognize the speech, determine whether the speech is uttered in a quiet voice, and control a movable part of a controlled apparatus in accordance with a result of the speech recognition. The at least one processor is configured to control the movable part of the controlled apparatus such that a sound pressure level of a sound generated by the movable part of the controlled apparatus is lower when it is determined that the speech is uttered in the quiet voice than when it is determined that the speech is not uttered in the quiet voice.

A robot includes a base, a spin body rotatably connected to the base, a tilting base tiltably connected at a tilting shaft to the spin body, a first tilting housing to which the tilting base is fixed therein, a second tilting housing which is fastened to the first tilting housing and to which the tilting base is fixed therein, and a tilting supporter connecting an inner side of the first tilting housing and an inner side of the second tilting housing. The tilting supporter is disposed at a position through which a rotational axis of the spin body passes.

An electronic device and method are disclosed. The device includes a housing, at least one camera, a plurality of microphones configured to detect a direction of a sound source, at least one driver operable to rotate and/or move at least part of the housing, a wireless communication circuit, a processor operatively connected to the camera, the microphones, the driver, and the wireless communication circuit, and a memory. The processor implements the method, including: receiving a user utterance, detect a first direction from which the user utterance originated, control the driver to rotate and/or move towards the first direction, a first image scan for the first direction and analyze the image for a presence of a user, when the user is not detected, rotate and/or move the at least part of the housing in a second direction, and perform a second image scan.

A robot is equipped with a processor. The processor detects external appearance or audio of a living being, and by controlling the robot, causes the robot to execute an operation in accordance with liking data indicating preferences of the robot regarding external appearance or audio and the detected external appearance or audio of the living being.

Not to give a noise to a subject to which it is not desired to give the noise. According to the present disclosure, a mobile unit control device including a noise estimation unit (434) that estimates, based on a position of a sound source and a sound volume generated by the sound source, a noise in a target region in which the noise is suppressed, and a control unit (436) that controls, based on the estimated noise, an operation of a mobile unit to reduce the noise in the target region is provided. With this configuration, it is possible not to give a noise to a subject to which it is not desired to give the noise.

A remote robot system and a method of controlling a remote robot system capable of responding appropriately according to a user are provided. A remote robot system includes: a robot configured to perform a predetermined operation including collection of local information near the robot; a guide terminal capable of remotely operating the operation of the robot; and a participant terminal capable of remotely communicating with the guide terminal, in which the participant terminal includes: a display panel configured to output the local information acquired from the robot to the user; and an interest detection unit configured to detect user's interest in the output local information.

One aspect of the invention is a robot system comprising a flexible artificial skin operable to be mechanically flexed under the control of a computational system. The system comprises a first set of software instructions operable to receive and process input images to determine that at least one human likely is present. The system comprises a second set of software instructions operable to determine a response to a perceived human presence, whereby the computational system shall output signals corresponding to the response, such that, in at least some instances, the output signals cause the controlled flexing of the artificial skin.

A construction site box for providing tools, power tools, power tool parts and/or consumables on a construction site, in particular on a building construction site or on a civil engineering construction site, is provided. The construction site box comprises at least one holder for holding a tool, a power tool, a power tool part and/or a consumable, a mobile transporting platform for transporting the construction site box and a motor for driving the transporting platform and enables a user of the construction site box to work on a construction site particularly efficiently and while safeguarding health.
