Ixys engineers contribute to published research on ROV controllability

January 4, 2026

Hardware Engineer Otto Nessa Ljosdal and Embedded Engineer Tomas Royal Choat have co-authored the scientific article “Controllability-driven optimization of underwater ROV design”, together with Professor Damiano Rotondo at the University of Stavanger (UiS).

Tomas Royal Choat and Otto Nessa Ljosdal, Ixys engineers and co-authors of the scientific article on underwater ROV controllability and design optimization.

SIMS 2025

The article was presented by Ljosdal at The 66th International Conference of the Scandinavian Simulation Society (SIMS 2025), held in Stavanger september 2025.

The research addresses a core challenge in underwater vehicle design: how the placement and orientation of thrusters impact controllability, maneuverability, and energy efficiency. By combining control theory, genetic algorithms, and simulation-based methods, the authors evaluated how different thruster configurations influence overall vehicle performance.

The topic explores how the placement and orientation of thrusters on underwater vehicles can be optimized for better controllability. By combining control theory, genetic algorithms, and simulations, they investigated how different configurations affect both maneuverability and energy consumption.

Otto sums up the experience:
“It was inspiring to share experiences and see how simulation-based methods contribute to new solutions in maritime technology, energy, automation, and health.”
