The problem addressed
Post-earthquake facade inspections put engineers at risk and progress too slowly, delaying safe damage classification of buildings.
Draft mission flow
- 1Deprem sonrasında sokak seviyesinden binaların dış cephelerini LiDAR ve HD kamerayla tarar.
- 2Cephe çatlakları genişlik ve derinlik olarak ölçülür; duvar eğilme açısı tilt sensörüyle belirlenir.
- 3Düşme riski olan balkon, parapet ve cephe kaplama parçaları kırmızı alan olarak işaretlenir.
- 4Hasar seviyesine göre bina sınıflandırması (yeşil/sarı/kırmızı) yapılarak AFAD'a iletilir.
Proposed hardware
- 3D LiDAR
- HD Zoom Kamera
- Termal Kamera
- Tilt Sensörü
- 5G İletişim
Proposed software
- Navigation
- Deprem bölgesi sokaklarında moloz ve hasarlı zemin üzerinde otonom yürüyüş SLAM
- Model
- Bina Cephe Çatlak Genişlik Ölçümü, Duvar Eğilme Analizi ve Düşme Riski Segmentasyonu
- Integration
- AFAD Deprem Hasar Değerlendirme Sistemi ve Belediye İmar Müdürlüğü

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.
