Centralized Control Device for Multi-Robot Message Diversity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems fail to prevent multiple output devices from providing identical responses to a user, as they often process and respond to user inputs independently without distinguishing between simultaneous or identical inputs from multiple devices.
Innovation Solution
A control device and message output control system that include a determining section to identify whether messages from multiple output devices are identical and a control section to either output a different message or suppress the message if identical, ensuring diverse responses from multiple robots or output devices interacting with a user.

Engineering Contradiction Analysis
1Speed
If multiple output devices independently process user inputs, then each device can respond autonomously and quickly, but identical messages are outputted from multiple devices to the same user
Solution Approach 1:
The patent merges the message determination functions of multiple output devices into a single centralized determination process. The control device receives utterance information from multiple output devices and centrally determines which device should output the message, preventing duplicate identical messages while maintaining autonomous processing capabilities at the device level.
Solution Approach 2:
The control device acts as an intermediary between multiple output devices and the user. It receives utterance information from output devices, determines message output assignments, and manages the overall response coordination, thereby ensuring message diversity while preserving fast autonomous response capabilities.
2Reliability
If a centralized control system manages message output from multiple devices, then message diversity is ensured, but system complexity increases
Solution Approach 1:
The control device performs multiple functions: it receives utterance information from multiple output devices, determines message output assignments, manages timing coordination, and ensures message diversity. This multi-functional approach consolidates control logic into a single device rather than requiring complex inter-device communication protocols.
Solution Approach 2:
The control device performs preliminary determination of message output assignments before actual message output occurs. By pre-determining which device should output which message based on received utterance information, the system avoids complex real-time coordination during message delivery, reducing overall system complexity.
3Productivity
If multiple output devices respond to the same utterance simultaneously, then response coverage is maximized, but identical messages are delivered to the user
Solution Approach 1:
The patent applies local quality by assigning different roles to different output devices based on the control device's determination. Instead of all devices performing the same function simultaneously, the control device designates specific devices for specific messages, creating localized functional differentiation that ensures message uniqueness while maintaining overall response coverage.
Solution Approach 2:
The system dynamically assigns message output responsibilities to different output devices based on the control device's real-time determination. Rather than static assignment, the control device flexibly decides which device should output which message based on received utterance information, maintaining both response coverage and message uniqueness through dynamic resource allocation.

AI summary
The present invention prevents a plurality of robots from outputting identical messages to a single user. The present invention includes a message determining section (83) that determines whether or not a message to be outputted from a robot (2) is identical to a first message to be outputted from a robot (1) or a second message which has been outputted from the robot (1). In a case where the message to be outputted from the robot (2) is identical to the first message or the second message, the message determining section (83) controls the robot (2) to (i) output a message different from the first message or the second message, or (ii) not to output any message.
