Autonomous Mobile Body Posture Control for Expressive Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous mobile bodies are limited in their motion expression and cannot easily enrich their movement patterns beyond basic front-back, turning, and rotation motions while maintaining a constant frontward tilting posture.
Innovation Solution
An information processing device with an operation controller that controls the moving operation of an autonomous mobile body while it maintains an inverted state, and also controls the posture operation of the autonomous mobile body to temporally change from a reference posture in the inverted state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the autonomous mobile body maintains a constant frontward tilting posture for stable movement, then the stability of movement is improved, but the motion expression becomes limited and cannot convey emotions
Solution Approach 1:
The patent applies dynamics by enabling the autonomous mobile body to dynamically adjust its posture angle while maintaining the inverted state. The operation controller allows temporal changes in posture from a reference posture, enabling the robot to express emotions through posture variations while preserving overall stability during movement.
2Device complexity
If the autonomous mobile body performs only basic moving operations (front-back motion, turning, rotation) in a standing state, then the device complexity is reduced, but the motion expression cannot be enriched
Solution Approach 1:
The patent applies parameter changes by modifying the posture angle parameter of the autonomous mobile body. Instead of adding complex mechanical structures, the system enriches motion expression by temporally varying the posture angle from a reference posture while maintaining the inverted state, achieving diverse expressions through simple parameter modulation.
