About the position

We have a vacancy for a PhD candidate at Department of Mechanical and Industrial Engineering.

The PhD scholarship is in the Robotics and Automation group. The research group has a large robot laboratory with a wide range of robots, robotic tools and vision systems, and includes computer solutions based on ROS/ROS2, industrial protocols and Industry 4.0. The research benefits from a synergy between the manufacturing industry with its strong focus on cost effective operations, and the offshore and maritime industries with high-value products in small batches. The scholarship is one of four PhD scholarships financed by a project on robotic welding of large aluminium structures, where the objective is to combine geometric data from CAD with robotic vision for efficient planning and execution of robotic welding. The project is a KPN project funded by the Research Council of Norway and the industrial partners, which are Hydro, Leirvik, Norsk Aluminium and Digitread.

You will report to Professor Olav Egeland

Duties of the position

  • The candidate will work on robotic solutions for welding of large aluminium structures, including CAD-based offline programming, weld seam localization and tracking, sensor calibration, automatic programming of multi-pass welds, and inspection of finished welds for trajectory planning and online adjustment of multi-pass welding operations. 
  • The solutions will be implemented in the robot laboratory of the department, which includes state-of-the-art robots, vision systems, laser scanners and welding equipment.
  • The lab implementation will be in a combination of industrial control systems and open source solutions like OpenCV and ROS/ROS2. 
  • The focus will be on the development of efficient solutions for CAD-based offline programming, calibration and execution of robotic welding for different design solutions for large structures in aluminium in close contact with the industry partners.

Required selection criteria

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is that you have completed a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in mechanical engineering or control systems, or equivalent education with a grade of B or better in terms of NTNU’s grading scale. If you do not have letter grades from previous studies, you must have an equally good academic foundation. If you are unable to meet these criteria you may be considered only if you can document that you are particularly suitable for education leading to a PhD degree.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, post doctor and research assistant.

Other required selection criteria

  • The candidate is required to have a good background in kinematics and geometric methods for industrial robots and robot vision systems. 

Preferred selection criteria

  • The candidate should have experience in software development for robot kinematics and robot vision, and the development of lab software for such systems.
  • Experience with ROS, OpenCV, Matlab, Python, and C++ is desired
  • Good written and oral Norwegian language skills is preferred but not required

Personal characteristics

  • Strong analytical skills
  • Good English communication skills, both oral and written
  • Strong motivation and positive attitude for teamwork

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal suitability.
