Robot Touch Detection and Autonomous Response Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robots lack the ability to autonomously respond to human interactions such as touch, failing to differentiate between petting and hitting, which limits their ability to engage in interactive and emotionally responsive play.
Innovation Solution
A robot equipped with a determiner to classify touch types and a controller that moves the robot closer when touched as 'petting' and further away when touched as 'hitting', utilizing action modes and touch reaction tables to vary responses based on touch frequency and intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the robot uses a simple touch detection mechanism, then the device complexity is reduced, but the ability to differentiate between petting and hitting is lost
Solution Approach 1:
The touch detection function is segmented into multiple independent sensors distributed across the robot's body surface. Each sensor detects local touch events, and the controller integrates information from multiple sensors to differentiate between petting and hitting based on patterns of activation, thereby achieving accurate touch type classification without requiring a single complex detection mechanism
Solution Approach 2:
The system dynamically adjusts its response based on real-time analysis of touch patterns. The controller continuously monitors touch duration, intensity, and spatial distribution, adapting its interpretation of touch types according to the dynamic characteristics of the interaction, enabling accurate differentiation between petting and hitting through temporal and spatial pattern recognition
2Extent of automation
If the robot autonomously responds to human interactions, then the extent of automation is improved, but the ability to accurately interpret touch intent deteriorates
Solution Approach 1:
The robot employs feedback mechanisms where the controller analyzes touch patterns from multiple sensors and adjusts its autonomous responses accordingly. The system uses feedback from touch duration, intensity, and spatial distribution to accurately interpret touch intent, enabling autonomous differentiation between petting and hitting while maintaining high automation in response generation
Solution Approach 2:
The controller pre-processes touch data by analyzing patterns from multiple sensors before generating autonomous responses. By performing preliminary analysis of touch characteristics such as duration, intensity, and spatial distribution, the system accurately interprets touch intent before executing autonomous actions, ensuring precise differentiation between petting and hitting
3Adaptability or versatility
If the robot moves closer when petted and away when hit, then the adaptability to human interaction is improved, but the device complexity increases
Solution Approach 1:
The movement control system is designed with multi-functionality to handle various interaction scenarios. The same controller that processes touch detection also manages movement responses, integrating multiple functions into a single system. This universal controller adapts its behavior based on touch type classification, enabling the robot to move closer when petted and away when hit without requiring separate dedicated systems for each function

AI summary
A robot includes a mover, a determiner, and a controller. The mover moves the robot. The determiner determines a touch type by a predetermined object. The controller controls the mover so as to move the robot close to the predetermined object when the determiner determines that the touch type by the predetermined object is petting, or so as to move the robot apart from the predetermined object when the determiner determines that the touch type by the predetermined object is to hitting.
