Abstract
A robot detects a voice using a microphone array, and identifies a sound source direction. The robot directs a head portion in the sound source direction. When an object including characteristics as a voice emitting body is detected in a filming region of a sound source direction identified using the microphone array, the voice emitting body is identified as a voice emission source. When a voice emitting body is identified as a voice emission source, the robot directs a body toward a sound source (emission source). When a special environmental sound is detected, a predetermined motion is executed.
Claims20
A robot, comprising:
- a microphone configured to receive at least one audio signal;
- a non-transitory computer readable medium configured to store instructions thereon;
- and
- a processor connected to the non-transitory computer readable medium, wherein the processor is configured to execute the instructions for:
- receiving information for each object of a plurality of objects;
- recognizing an object of the plurality of objects associated with each audio signal of the received at least one audio signal;
- updating information associated with the recognized object based on the received at least one audio signal;
- determining a priority of the recognized object among the plurality of objects, in response to the at least one audio signal comprising a plurality of audio signals, based on the updated information;
- selecting a response for execution by the robot based on the determined priority and the at least one audio signal;
- determining a direction of the received at least one audio signal;
- controlling an image displayed in the robot;
- and
- selecting the response of causing the image to move in the determined direction.

A robot, comprising:
- a microphone configured to receive audio signals;
- a non-transitory computer readable medium configured to store instructions thereon;
- and
- a processor connected to the non-transitory computer readable medium, wherein the processor is configured to execute the instructions for:
- identifying a first object associated with a first audio signal of the received audio signal;
- identifying a second object associated with a second audio signal of the received audio signal;
- determining whether the first object has a higher priority than the second object;
- selecting a first response for execution by the robot in response to the first object having a higher priority than the second object;
- selecting a second response for execution by the robot in response to the second object having a higher priority than the first object;
- determining a direction of the received first audio signal;
- controlling an image displayed in the robot;
- and
- selecting the first response of causing the image to move in the determined direction;
- and
- transmitting instructions for executing only one of the first response or the second response.
