The problem addressed
Excavation pits changing daily on construction sites and unbarriered areas causing fall accidents.
Draft mission flow
- 1The robot patrols autonomously on the construction site, detecting open pits, trenches, and unbarriered elevation differences with LiDAR and depth camera.
- 2Depth, width, and perimeter barrier status of each hazardous area evaluated; unbarriered areas scored as 'urgent risk'.
- 3Instant LED warning and siren alert given to personnel approaching hazardous area; location and photo notification sent to OHS platform.
- 4Daily hazard map updated and presented to site manager at morning briefing; barrier deficiency opened as work order.
Proposed hardware
- 3D LiDAR
- HD Depth Camera
- LED Warning Lights
- High Decibel Siren
Proposed software
- Navigation
- Safe SLAM navigation with edge detection around excavation areas
- Model
- Open Pit Depth Estimation and Unbarriered Hazardous Area Segmentation
- Integration
- Construction Site OHS Platform and Daily Hazard Map

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.
