The problem addressed
Scaffolding cost and time loss for inspecting hard-to-reach weld points; risk of incomplete NDT inspection.
Draft mission flow
- 1The robot enters between steel constructions inaccessible to humans without scaffolding and photographs weld points up close.
- 2Detects porosity, cracks, and undercut defects in weld seams at micron level with 100MP macro camera.
- 3Ultrasonic thickness gauge verifies weld penetration depth; non-standard welds reported.
- 4All findings transmitted to NDT reporting system with photographs, location, and defect class; corrective welding work order auto-opened.
Proposed hardware
- 100MP Macro Optical Camera
- Ultrasonic Thickness Gauge
- Lighting Kit
- Long Range WiFi 6E
Proposed software
- Navigation
- Adaptive SLAM in narrow passages and under stairs among steel constructions
- Model
- Weld Seam Porosity, Crack and Insufficient Penetration Classification (Custom CNN)
- Integration
- Structural Engineering NDT (Non-Destructive Testing) Reporting 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.
