Pet Robot Audio Control for State-Based Emotional Expression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet-type robots lack the ability to express emotions and intentions effectively through operation sounds and sound effects.
Innovation Solution
An autonomous mobile body equipped with an operation control unit, recognition unit, and audio control unit that generates and processes audio data based on the robot's state, allowing for dynamic expression through audio characteristics and timing control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pet-type robot executes movements and performances to express intention and feeling, then ability of expression is improved, but without operation sound and sound effect the expression capability is insufficient
Solution Approach 1:
The audio control unit generates operation sounds and sound effects autonomously based on recognition results from the recognition unit, without requiring external audio files or complex pre-programmed sound libraries. The system self-generates appropriate audio outputs dynamically
Solution Approach 2:
The audio control unit changes audio parameters such as pitch, volume, and timing dynamically based on the robot's operational state and recognition results, enabling flexible expression without requiring multiple fixed audio clips
2Manufacturing precision
If audio data is generated and processed dynamically based on operation state, then expression accuracy is improved, but processing time and computational load increase
Solution Approach 1:
The system performs preliminary processing by pre-defining audio generation rules and parameters based on operational states, so that when actual operation occurs, the audio control unit only needs to apply pre-established patterns rather than generating audio from scratch
Solution Approach 2:
The audio control unit receives feedback from the recognition unit about the robot's operational state and adjusts audio generation accordingly, ensuring accurate expression while optimizing processing efficiency through real-time state-responsive audio synthesis

AI summary
The present technology relates to an autonomous mobile body, an information processing method, and a program enabling improvement in ability of expression by audio of an autonomous mobile body. An autonomous mobile body includes an operation control unit that controls an operation of the autonomous mobile body, a recognition unit that recognizes a state of the autonomous mobile body in operation, and an audio control unit that generates or processes audio data corresponding to audio to be output in accordance with the operation of the autonomous mobile body on the basis of a recognition result of the state of the autonomous mobile body, and controls a characteristic and an output timing of the audio. The present technology can be applied to, for example, a pet-type robot.
