Robot Contact Event Scoring Using Active vs Passive Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack effective methods to detect and utilize unexpected motions in robots, particularly for entertainment purposes, such as physical interactions between robots.
Innovation Solution
An information processing device and system that includes contact event detection, activeness determination, and score increase sections to detect and determine the activeness of contact events between robots, allowing for the scoring of robots based on active and passive contact events during interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If contact events are detected on both robots, then the system can identify physical interactions, but it cannot distinguish between active attacks and passive receptions
Solution Approach 1:
The patent applies local quality by determining activeness separately for each robot's contact event. The activeness determination section evaluates whether each contact event occurred on a moved portion (indicating active attack) or stationary portion (indicating passive reception) of the robot housing, allowing differentiation between attacker and receiver roles
Solution Approach 2:
The patent introduces an intermediary activeness determination mechanism that processes contact event data from both robots. By comparing the motion state of each robot at the time of contact, the system mediates between the two contact detections to determine which robot was actively attacking and which was passively receiving
2Adaptability or versatility
If the system scores robots based on contact events, then entertainment value increases, but fairness decreases without activeness determination
Solution Approach 1:
The patent implements feedback by using activeness determination results to control score assignment. The score increase section receives feedback from the activeness determination section about which robot was active, and only increases the score of the active robot, ensuring fair scoring that reflects actual attack behavior rather than merely contact occurrence
3Device complexity
If the system only detects contact events without determining activeness, then detection simplicity is maintained, but utilization of unexpected motions is insufficient
Solution Approach 1:
The patent applies preliminary action by determining activeness at the moment of contact event detection. The activeness determination section evaluates the motion state of robots before and during contact, preparing activeness information that enables immediate and accurate scoring decisions without requiring complex post-processing analysis

AI summary
Provided is an information processing device including a contact event detection result acquisition section, an activeness determination result acquisition section, and a score increase section. The contact event detection result acquisition section acquires a result of detection of a first contact event and a result of detection of a second contact event. The first contact event has occurred on a part of a housing of a first robot. The second contact event has occurred on a part of a housing of a second robot. The activeness determination result acquisition section acquires a result of determination of activeness of each of the first and second contact events. The score increase section increases a score of the first robot in a case where the first contact event is active and the second contact event detected synchronously with the first contact event is inactive.
