Underground Shelter and Tunnel Security Inspection
Scenario record: it defines the environment, the mission flow and a proposed hardware and software configuration. The list below is a configuration proposal, not an installation inventory. Field projects lists deployed systems and their measurements.
- Environment
- Outdoor field
- Operating mode
- Supervised autonomy
- Proposed robot
- Unitree A2
The problem addressed
Inability to periodically inspect thousands of underground shelters due to personnel and time constraints.
Draft mission flow
- 1The robot enters shelter and tunnel systems, conducting autonomous reconnaissance in darkness with night vision and LiDAR.
- 2Detects structural cracks, water seepage, and collapse risk areas; measures air quality with gas detector.
- 3Shelter usability status (door functionality, ventilation, capacity) evaluated.
- 4Detailed maintenance report presented to civil defense directorate; areas requiring urgent maintenance prioritized.
Proposed hardware
- HD Night Vision Camera
- Multi-Gas Detector (O₂/CO/CH₄)
- LiDAR L2
- Tactical Communication
Proposed software
- Navigation
- LiDAR-based corridor SLAM without illumination in narrow tunnels and shelter corridors
- Model
- Structural Damage Detection (Crack, Water Seepage, Collapse Risk) and Air Quality Assessment
- Integration
- Civil Defense Directorate and Municipal Infrastructure Management System

Values are manufacturer data. Scenario fit is determined by comparing these limits with site conditions.
From scenario to installation
Feasibility is determined by the site survey: floor and route, network coverage, the charging point, intervention responsibilities and the conditions under which the robot must stop. The survey report defines the scope, the constraints and the commissioning steps.
