Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If local communication by near-field wireless node is performed between robots, then data sharing among robots is achieved, but movement of robots is restricted due to non-long effective distance
Solution Approach 1:
The patent introduces a gateway device as an intermediary that relays communication between robots. When robots are outside direct communication range, the gateway acts as a mediator to forward data, enabling robots to move freely while maintaining data sharing capabilities through indirect communication paths.
Solution Approach 2:
The patent extends the communication network from direct peer-to-peer links to include multi-hop paths through gateways. This adds a new dimension to the communication topology, allowing robots to maintain connectivity even when physically separated beyond direct transmission range by utilizing alternative communication routes.
2Reliability
If restrictions are imposed on robot movement to maintain communication network, then communication stability is improved, but task performance efficiency deteriorates
Solution Approach 1:
The gateway device serves as a stable communication anchor point that maintains network reliability. Robots can move freely while the gateway provides a consistent relay node, ensuring communication stability without imposing movement restrictions on the robots themselves.
Solution Approach 2:
The communication network dynamically adapts to robot movements by utilizing the gateway as a flexible relay. The system transitions from static communication pairs to dynamic multi-hop paths, allowing robots to change positions while maintaining stable communication through the gateway intermediary.
3Adaptability or versatility
If robots operate in distributed situations, then system scalability is improved, but communication effectiveness deteriorates due to distance limitations
Solution Approach 1:
The gateway acts as a central intermediary that enables distributed robots to communicate effectively regardless of distance. Each robot communicates with the gateway, which relays information across the network, allowing scalable distribution while maintaining communication effectiveness through the mediator.
Solution Approach 2:
The system implements feedback mechanisms where robots report their positions and task status to the gateway, which coordinates communication routing. This feedback loop ensures that even in distributed configurations, information flows effectively through the gateway's coordination of multi-hop communication paths.

AI summary
An acquisition unit (11) acquires information indicating the task performance ability possessed by one or more other autonomous behavior apparatuses. On the basis of the task performance ability possessed by a first autonomous behavior apparatus and the task performance ability possessed by the one or more other autonomous behavior apparatuses, a determination unit (12) determines a destination for the first autonomous behavior apparatus. A connection unit (13) communicatively connects a second autonomous behavior apparatus and the first autonomous behavior apparatus, said second autonomous behavior apparatus being among the one more more other autonomous behavior apparatuses with which the first autonomous behavior apparatus can communicate. A movement control unit (14) causes the first autonomous behavior apparatus to move to the destination while the communicative connection between the second autonomous behavior apparatus and the first autonomous behavior apparatus is maintained.
