UGV Sensor Module Mounting With Rotating Elbow Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned ground vehicles require flexible and rapid system modifications to adapt to various mission requirements, particularly in field operations, where existing solutions lack ease and efficiency in mounting and repositioning sensor modules for effective surveillance and reconnaissance.
Innovation Solution
The unmanned ground vehicle design incorporates a manipulator arm with an independently rotating elbow, allowing for the simple and rapid repositioning of a sensor module along the arm, including multiple mounting options such as bolts, straps, and picatinny rails, enabling tool-less attachment and detachment for enhanced situational awareness and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sensor module is mounted on the main body, then the mounting structure is simple, but the adaptability and repositioning flexibility are limited
Solution Approach 1:
The manipulator arm is divided into multiple segments (first link, elbow, second link) that can move independently relative to each other, allowing the sensor module to be repositioned to various locations while keeping the base mounting structure relatively simple
Solution Approach 2:
The manipulator arm serves multiple functions: it positions the sensor module for different mission requirements, provides structural support, and enables tool-less attachment/detachment. This multi-functionality addresses adaptability needs without proportionally increasing complexity
2Productivity
If traditional mounting methods are used, then the attachment is secure, but the time required for mounting and repositioning is excessive
Solution Approach 1:
The manipulator arm provides dynamic positioning capability, allowing rapid movement between different sensor locations. Combined with quick-release mounting interfaces, this enables fast reconfiguration while maintaining secure attachment during operation
Solution Approach 2:
The manipulator arm acts as an intermediary structure between the main body and sensor module, providing both mechanical support for secure mounting and mobility for rapid repositioning. The arm absorbs the complexity of movement while maintaining simple attachment interfaces
3Adaptability or versatility
If the sensor module is fixed in position, then the mounting structure is simple, but the adaptability to various mission requirements is reduced
Solution Approach 1:
The manipulator arm enables dynamic reconfiguration of the sensor system in the field without requiring complex tools or procedures. The independent rotation of the elbow and movement of links allows operators to quickly adapt sensor positioning to different mission requirements
Solution Approach 2:
The manipulator arm's mounting system is designed to be self-sufficient, with integrated mounting interfaces and tool-less attachment mechanisms that allow field personnel to reconfigure the sensor module independently without specialized equipment or complex procedures
