Active Docking Mechanism for Modular Reconfigurable Robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional robots face limitations in adapting to varying terrain and scalability, as they are often rigid and lack the ability to efficiently switch between mobility mechanisms, which can hinder their ability to perform tasks in diverse environments and require human intervention for repairs.
Innovation Solution
A self-configurable and transformable omni-directional robotic module (STORM) that combines tracked and wheeled units with a toggling mechanism for omni-directional mobility, allowing it to switch between mobility modes and dock with other modules for enhanced versatility and scalability, enabling it to navigate different terrains and perform complex tasks autonomously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a robot uses a fixed mobility mechanism (either tracked or wheeled), then the structure is simple and reliable, but the robot cannot adapt to varying terrain conditions
Solution Approach 1:
The robot employs a dynamic mobility system that can switch between tracked and wheeled configurations based on terrain conditions. The toggling mechanism allows the robot to change its mobility mode actively, making the system adaptable rather than static. This resolves the contradiction by introducing controlled variability to match external environmental demands.
Solution Approach 2:
The robot integrates both tracked and wheeled mobility mechanisms within a single platform, enabling it to perform multiple functions across different terrain types. The universal base structure supports both mobility modes, allowing the robot to handle diverse terrain conditions without requiring separate specialized robots.
2Adaptability or versatility
If a robot is designed as a rigid single structure, then manufacturing is simpler, but the robot cannot reconfigure for different tasks or repair faulty parts
Solution Approach 1:
The robot is divided into modular segments that can be independently manufactured, docked, and reconfigured. Each module can be produced separately using standardized interfaces, maintaining manufacturing simplicity while enabling flexible assembly and reconfiguration for different tasks or repair scenarios.
Solution Approach 2:
The robot transitions from a static rigid structure to a dynamic reconfigurable system through active docking mechanisms. Modules can be connected or disconnected based on task requirements, and the system can adapt its morphology dynamically rather than being fixed in a single configuration.
3Adaptability or versatility
If a robot switches between tracked and wheeled modes, then terrain adaptability improves, but the toggling mechanism increases device complexity
Solution Approach 1:
The toggling mechanism is integrated into the existing modular architecture of the robot, combining the mode-switching function with the module docking system. This merging approach allows the same mechanical interfaces and control systems to handle both module attachment and mobility mode transitions, reducing overall system complexity.
4Productivity
If a robot uses modular architecture for reconfigurability, then task sharing and scalability improve, but docking precision requirements increase
Solution Approach 1:
The docking system incorporates self-alignment features where modules automatically adjust their relative positions during the docking process. Sensors and active control mechanisms enable modules to find and maintain proper alignment autonomously, reducing the stringency of pre-docking alignment requirements and simplifying the overall docking precision demands.

AI summary
A robot has a track assembly having tracks configured to move the robot in a first direction and a wheel assembly having wheels configured to move the robot in a second direction orthogonal to the first direction. A toggling assembly switches between the track assembly and the wheel assembly. The robot modules can mate with each other. The robot module has an elongated shaft with a head and a narrow neck. The shaft extends outward from the side of the robot module. A mating robot module has a clamping mechanism with opposing clamps which in an opened position receive the shaft. In a closed position, the clamps define an opening which matches and engages the cross-section of the neck of the elongated shaft. The clamping mechanism has a drive mode to drive the module, a clamping mode for docking, and neutral mode for alignment prior to clamping.
