The problem addressed
The disaster of the flood's invisible destructive power causing collapses onto vehicles after roads reopen to traffic.
Draft mission flow
- 1Sel felaketi veya kasırga geçtikten saatler sonra riskli viyadüklerin veya şehir içi köprülerin altına gider.
- 2Sonarıyla suyun içindeki köprü ayaklarının altının (kumun) oyulup oyulmadığını (Scour) tespit eder.
- 3Köprünün üstünden ağır bir TIR geçerse köprünün yıkılıp yıkılmayacağını statik modellerle valiliğe bildirir.
Proposed hardware
- Sonarlı Ultrasonik Mesafe Ölçer
- Zemin Yumuşaklık (Baskı) Pedleri
- Su İtici Eklem Contaları
Proposed software
- Navigation
- Akıntılı çamurlu su kalıntıları üzerinde ayakların batmasına (Sinkage) duyarlı kinemati
- Model
- Su Altı Kolon Erozyonu (Scour) ve Statik Risk Hesaplama
- Integration
- Karayolları Sel ve Acil Müdahale Masası

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.
