Contrary to the common belief held by Arctic researchers for many years, Icebergs are not trapezoidal underwater. This has been revealed by a complete 3D scan of icebergs off the west coast of Greenland.
In its current form, the robot can dive to 50 meters, and its design is waterproof so that the technological hardware in the belly of the robot is not damaged. It maneuvers safely and with great accuracy in extremely cold waters, and at the same time, the specific angle of its lights illuminates the surroundings, allowing for impressive image quality.
All this was achieved in just one semester, but the project team has also had to work hard, as Johan T. Krogshave, another engineering student from the project team says:
"Sure, we’ve been busy. We had to be ready for the expedition after just a few months. The biggest engineering challenge was to keep down the robot's weight and size. But water resistance has also been an issue, because we’ve used materials that expand at different temperatures. Fortunately, we’ve reached all our goals."

Three happy engineering students back in Aarhus after a successful expedition to Greenland. In the course of just one semester, they have built an underwater robot that can explore icebergs below the ocean surface.
