## Two-Robot Hazard Detection System
* Project overview using ROS and Gazebo to simulate a hospital environment.
* Dual-robot system designed to detect and report hazards autonomously.

## System Architecture & Workflow
* Step-by-step process: Launching robots, generating random hazard locations, autonomous navigation, scanning, and generating reports.
* Robots operate simultaneously and independently within the map.

## Navigation & Goal Management
* Addressing the challenge of 'collision meshes' where visual space does not equal navigable space.
* Valid positions mapped include hospital beds, wheelchairs, and open corridors.

## Hazard & Movement Visualization
* Design of high-visibility hazard markers (yellow base with red X) for Gazebo.
* Real-time trail system: Teal/green trail for Robot 1 and Orange trail for Robot 2 to track coverage.

## Automated Reporting System
* ROS-based reporting covering: Robot ID, Location coordinates, Hazard Type, and Recommended Action.
* Example detection: Robot 1 detected a 'Chemical Spill' at (3.2, 1.8).
* Example detection: Robot 2 detected an 'Electrical Risk' at (7.5, 4.1).

## Conclusion & Future Work
* Focus on bridging the gap between simulation appearance and physical navigability.
* Future development includes integration of real camera sensors for data-driven detection.
