Embodiment Construction

[0036] figure 1 (a) is a front appearance view of the robot 100 . figure 1 (b) is a side external view of the robot 100 .

[0037] The robot 100 in the present embodiment is a behavior-autonomous robot that determines behavior and gesture (gesture) based on the external environment and internal state. The external environment is recognized by various sensors such as a camera and a thermo sensor. The internal state is quantified into various parameters representing the emotion of the robot 100 . This will be explained later.

[0038] The robot 100 presupposes the movement in the house, for example, the house of the owner's house as the movement range. Hereinafter, a person related to the robot 100 is referred to as a "user", and a user who is a member of the family to which the robot 100 belongs is referred to as a "master".

[0039] The main body 104 of the robot 100 has a rounded shape as a whole, and includes an outer skin made of soft and elastic materials such as poly...

Abstract

The robot uses a microphone array to detect a sound and identify the direction of a sound source. The robot faces a head portion in the direction of the sound source. If an object having a characteristic of an uttering body is detected in an image capturing region (420) in the direction of the sound source identified by the microphone array, the uttering body is identified as an utterance source.Upon identifying the uttering body as the utterance source, the robot faces a body thereof toward the sound source (utterance source). The robot executes a predetermined motion if a particular environmental sound is detected.

Description

technical field [0001] The present invention relates to a robot that autonomously makes behavior choices according to internal state or external environment. Background technique [0002] Hearing is one of the basic senses of living things. For hearing, it is not only important to identify the type of sound by identifying the three elements of sound, namely loudness (sound pressure), timbre (frequency), and pitch (waveform), but also to determine the direction of the sound source. [0003] A microphone array is a device that can determine the direction of a sound source by carrying multiple microphones. When a sound is emitted from a certain sound source, each of the plurality of microphones collects sound. Depending on where the microphones are installed, the timing at which the sound reaches each microphone varies slightly. According to the deviation at this time point, the sound source direction is determined. Microphone arrays are highly anticipated as the "ears" of ...
