Modular Robot Assembly for Fast Replacement and Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex assembly and maintenance of robots, which often require substantial disassembly to replace individual components, make it difficult to configure, repair, or modify them, limiting their versatility and efficiency.
Innovation Solution
A modular approach where robot components are produced separately as individual units and assembled using attachment mechanisms and connectors, allowing easy coupling and decoupling, and a control system that identifies and configures the operation based on the characteristics of each modular component.

Engineering Contradiction Analysis
1Ease of repair
If robot components are assembled as a complex integrated system, then the robot achieves complete functionality, but maintenance and repair require substantial disassembly making it difficult and time-consuming
Solution Approach 1:
The robot system is divided into independent modular components (locomotion module, manipulator module, sensor module, power module, controller module) that can be separately assembled, maintained, and replaced. Each module functions independently while connecting to the overall system through standardized interfaces, enabling easy maintenance without complete disassembly.
2Adaptability or versatility
If robot components are designed as fixed integrated units, then structural stability is maintained, but reconfiguration for different tasks becomes difficult
Solution Approach 1:
The robot employs universal standardized interfaces (mechanical attachment mechanisms, electrical connectors, communication protocols) that allow different modular components to be interchangeably assembled. This enables the same base platform to be reconfigured for various tasks by swapping modules, achieving multi-functionality without designing multiple complete robot systems.
3Ease of repair
If individual components are replaced in a complex assembled robot, then system functionality is restored, but the replacement process is difficult and requires extensive disassembly
Solution Approach 1:
The robot is segmented into independently replaceable modules with standardized connection interfaces. When a component fails, only the affected module needs to be detached and replaced, not the entire robot system. This dramatically reduces maintenance time and effort while restoring system functionality.
4Ease of manufacture
If the robot system uses standardized modular interfaces, then ease of assembly and maintenance is improved, but the initial design and integration becomes more complex
Solution Approach 1:
Universal standardized interfaces are designed with clear mechanical attachment mechanisms, electrical connector configurations, and communication protocols. While the initial interface design requires careful planning, it enables all subsequent module assemblies to follow the same standardized procedure, simplifying manufacturing and maintenance processes.

AI summary
A robotic system includes a body including at least one attachment mechanism configured to removably couple a modular component to the body. The modular component includes at least one movable part operable to move relative to the body when the modular component is attached to the body. The system includes a communication interface coupled to the body and configured to be communicatively coupled to the modular component to receive information relating to the modular component and operation of the at least one movable part. The system includes a control system coupled to the body and the communication interface. The control system is configured to: in response to the modular component being attached to the body, receive the information from the modular component by way of the communication interface, and operate the at least one movable part of the modular component according to the information.
