- Supervised autonomy
- Proposed robot
- Unitree A2
The problem addressed
Torque tightening errors that lead to wheel or axle detachment after the vehicle leaves the factory.
Draft mission flow
- 1Robot, konveyörde ilerleyen aracın altına esneyerek / sürünerek girer.
- 2İnsan operatörlerin sıktığı süspansiyon ve şasi cıvatalarının üzerine çekilen boya güvenlik çizgilerini (Tork Çizgileri) okur.
- 3Çizgisi eksik veya kaymış (gevşek) cıvatayı bulduğunda sistemde şasi (VIN) numarasıyla arıza kaydı açar.
Proposed hardware
- Robot Kol + Optik Makro Lens
- Aydınlatma Projektörü
- Ağırlık Sensörleri
Proposed software
- Navigation
- Askıdaki veya banttaki araçların altına girerek (Crouching) yürütme otonomisi
- Model
- Geometrik Cıvata Dişi Çıkarımı ve Boya Çizgisi OCR Okuma
- Integration
- Otomotiv ERP / Kalite Kontrol Sistemi (QMS)

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.
