Bluetooth Device Subgrouping for Scalable Modular Robot Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling multiple Bluetooth devices simultaneously are inefficient, particularly in modular robot systems where various shapes and functions are needed, leading to increased purchase costs and limited functionality in robot toys.
Innovation Solution
A method for forming a group of Bluetooth devices by creating subgroups, where each device can function as both a central and peripheral device, allowing for the formation of a hierarchical structure that enables all devices to be controlled by a central device, facilitating complex motions and shapes in modular robots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple Bluetooth devices are controlled simultaneously using existing methods, then control capability is provided, but control efficiency is low and device complexity increases
Solution Approach 1:
The patent divides a large group of Bluetooth devices into multiple subgroups, with each subgroup managed by a designated Bluetooth mediating device. This segmentation reduces the control burden on the central device and improves control efficiency by distributing management responsibilities across multiple mediating devices within each subgroup.
Solution Approach 2:
The patent introduces Bluetooth mediating devices that act as intermediaries between the central Bluetooth device and peripheral devices. These mediating devices receive control commands from the central device and relay them to peripheral devices, simplifying the overall control structure and improving efficiency by reducing direct communication overhead.
2Adaptability or versatility
If robot toys are configured with fixed functions and motions, then manufacturing is simplified, but adaptability and functionality are limited
Solution Approach 1:
The patent enables Bluetooth devices to dynamically change their roles between central and peripheral devices based on group formation needs. This multi-functionality allows the same hardware to serve different purposes in different configurations, increasing adaptability without requiring additional specialized components for each function.
Solution Approach 2:
The patent implements dynamic role assignment where Bluetooth devices can switch between central and peripheral roles during group formation and operation. This dynamic configuration allows the system to adapt to different functional requirements and group sizes, providing versatility while maintaining manageable system complexity through automated role distribution.

AI summary
A method for forming a group from a plurality of Bluetooth devices includes forming one subgroup with some of the plurality of Bluetooth devices; and, with respect to Bluetooth mediating devices that are at least some of the plurality of Bluetooth devices belonging to the subgroup, forming, by the Bluetooth mediating device, one lower subgroup having the subgroup as an upper subgroup thereof, together with the plurality of Bluetooth devices which do not yet belong to any subgroup.
