    • Automatic touch-up of welding paths using 3D vision 

      Njåstad, Eirik Bjørndal; Egeland, Olav (Journal article; Peer reviewed, 2016)
      This paper presents a system for automatic robotic welding based on offline programming using CAD data. The welding paths are corrected before execution with 3D vision where the 3D image is aligned with the CAD model of ...

    • Learning to grasp: A study of learning-based methods for robotic grasping 

      Høeg, Sigmund Hennum (Master thesis, 2022)
      Roboter i dag brukes først og fremst til oppgaver som er repetitive og forutsigbare. Men mange oppgaver som skaper verdi for samfunnet vårt inkluderer høy grad av tilfeldighet, for eksempel å plukke opp gjenstander. På ...

    • Planning of robotic inspection from visual tracking of manual surface finishing tool. 

      Njåstad, Eirik Bjørndal; Egeland, Olav (Peer reviewed; Journal article, 2019)
      A planning system for efficient of robotic inspection of surface tolerances is presented. This is done using visual tracking of a manual polishing tool. The application that is studied is surface finishing of large ship ...

    • Residual vibration control for robotic 3D scanning with application to inspection of marine propellers 

      Njåstad, Eirik Bjørndal; Tysse, Geir Ole; Egeland, Olav (Peer reviewed; Journal article, 2021)
      Abstract: This paper presents a system for 3D scanning of a large marine propeller blade with a 3D camera mounted on an industrial robot. An industrial 3D camera with structured light is used where the accuracy is in the ...

    • Robotic 3D Scanning and Inspection of Marine Propellers 

      Njåstad, Eirik Bjørndal (Doctoral theses at NTNU;2021:417, Doctoral thesis, 2021)

    • Robotic Autoscanning of Highly Skewed Ship Propeller Blades 

      Njåstad, Eirik Bjørndal; Munthe-Kaas, Njål; Egeland, Olav (Journal article; Peer reviewed, 2018)
      This paper presents an approach for a complete scanning of ship propeller blades. Inline quality control for advanced manufacturing or inspection of operational propeller blades requires automated and highly accurate 3D ...

    • Robotsveising med korreksjon fra 3D-kamera 

      Njåstad, Eirik Bjørndal (Master thesis, 2015)
      Robotisert sveising benyttes for tilvirkning av mange slags produkter. I denne masteroppgaven har muligheten for å integrere et 3D kamera i et sveiserobotsystem blitt vurdert, med sikte på å forbedre programmeringsprosessen ...
