Provided is a robot including a microphone configured to acquire a sound signal corresponding to a sound generated near the robot, a camera, an output interface including at least one of a display configured to output a wake-up screen or a speaker configured to output a wake-up sound when the robot wakes up, and a processor configured to recognize whether the acquired sound includes a voice of a person, activate the camera when the sound includes a voice of a person, recognize whether a person is present in an image acquired by the activated camera, set a wake-up word recognition sensitivity based on a recognition result as to whether a person is present, and recognize whether a wake-up word is included voice data of a user acquired through the microphone based on the set wake-up word recognition sensitivity.

Certain aspects relate to systems and techniques for preparing a robotic system for surgery. In one aspect, the method includes a robotic arm, a sensor configured to generate information indicative of a location of the robotic arm, a processor, and at least one computer-readable memory in communication with the processor and having stored thereon computer-executable instructions. The instructions are configured to cause the processor to receive the information from the sensor, determine that the robotic arm is located at a first position in which a first axis associated with the robotic arm is not in alignment with a second axis associated with a port installed in a patient, and provide a command to move the robotic arm to a second position in which the first axis associated with the robotic arm is in alignment with the second axis.

An inspection device includes an oscillator for generating ultrasonic waves toward a first connector, and a vibration receiver for receiving vibrations generated in the first connector. The inspection device includes a vibration controller for analyzing the vibrations received by the vibration receiver. The vibration controller detects a resonance frequency by converting, by Fourier transform, the vibrations received by the vibration receiver. The vibration controller determines an insertion amount of the first connector into the second connector, based on the detected resonance frequency.

Disclosed are a robot system and a control method for the same. The robot includes a first server, a first robot registered on the first server and configured to deliver goods to a client according to information received from the first server, a second robot configured to receive the delivery goods from the first robot, and a second server having the second robot registered thereon and being configured to operate the second robot. The control method for the robot system may include: confirming, by the first robot, whether a person is present in a surrounding area of delivery destination; when someone is present, acquiring, by the first robot, voice information and image information of the present person and transferring the same to the second robot; transferring, by the second robot, the voice information and the image information of the person to the second server; recognizing, by the second server, a person from at least one of the voice information and the image information of the person transferred from the second robot, and transferring a recognition result to the second robot; confirming, by the second robot, whether the present person is a family member of the client, based on the recognition result of the person transferred from the second server; and when the present person is a family member, transferring, by the first robot, the delivery goods to the present person.

An artificial intelligence (AI) device, such as a robot, comprises: an output interface to output content in response to a request of a user; a camera to acquire an image of the user; a microphone to acquire a voice signal including a voice content uttered by the user; a processor to determine a characteristic of the user based on the content, the image, and/or the voice signal, and recognize the voice content through a voice recognition mode corresponding to the determined characteristic. The AI device may include a communication interface to forward the voice signal to a remote computer that identifies the characteristic and recognizes the voice content based on the characteristic. According to an embodiment, when an irregular voice is recognized from the acquired voice signal, the processor may recognize a regular voice corresponding to the irregular voice using an artificial intelligence-based learning model.
