Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robotic vehicles face challenges in navigating hazardous environments, including rugged terrain and semi-submerged conditions, while providing effective communication and reconnaissance, especially in applications like underground mining accidents, where they need to traverse rough terrain, sense environmental parameters, and maintain mobility in explosive or oxygen-deprived atmospheres.
Innovation Solution
A robotic vehicle with mechanically linked tracked mobility platforms, featuring explosion-proof sealed compartments, a two-degree-of-freedom coupling for enhanced mobility, and communication via radio frequency and fiber optic links, along with edge-scallop cut-outs on tracks for improved traction and a pan and tilt support mast for sensors and cameras, allowing semi-submersible operation and remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single tracked mobility platform is used, then the vehicle structure is simple, but the mobility on rugged terrain and in water is insufficient
Solution Approach 1:
The vehicle is divided into two separate tracked mobility platforms (first and second platforms) that are mechanically linked together. Each platform can independently traverse different terrains, and when connected, they form a composite vehicle with enhanced mobility capabilities on both rugged terrain and water surfaces.
2Productivity
If standard tracks are used, then the manufacturing is simple, but the traction on rugged terrain and in water is insufficient
Solution Approach 1:
The tracks are designed with edge-scallop cut-outs at specific locations along the track edges. This local modification creates scallop-shaped openings that improve traction by allowing the tracks to better engage with terrain features and water surfaces, while maintaining the overall simplicity of the track structure.
3Reliability
If electronic components are exposed, then the vehicle operation is simple, but the reliability in hazardous environments is insufficient
Solution Approach 1:
Multiple sealed compartments are integrated into the vehicle structure, each housing specific electronic components. These compartments provide explosion-proof and environmental protection while maintaining a relatively simple overall vehicle design. The compartments are strategically positioned to protect sensitive electronics from hazardous conditions.
4Reliability
If communication links are external only, then the vehicle design is simple, but the communication reliability when links are lost is insufficient
Solution Approach 1:
The vehicle is equipped with autonomous capabilities that allow it to perform self-rescue maneuvers and navigate back to a known location when communication with the remote operator is lost. The vehicle can independently detect communication failures and execute pre-programmed recovery procedures without external assistance.

AI summary
A robotic vehicle having two or more tracked mobility platforms that are mechanically linked together with a two-dimensional coupling, thereby forming a composite vehicle of increased mobility. The robotic vehicle is operative in hazardous environments and can be capable of semi-submersible operation. The robotic vehicle is capable of remote controlled operation via radio frequency and/or fiber optic communication link to a remote operator control unit. The tracks have a plurality of track-edge scallop cut-outs that allow the tracks to easily grab onto and roll across railroad tracks, especially when crossing the railroad tracks at an oblique angle.
