The underwater robot DeepFreeze has provided polar researchers with very detailed knowledge about ice algae, which are the key to understanding life in the Antarctic waters. Pictured here are Tor Dam Eskildsen and Thomas Juul, who designed and built the robot for the researchers. (Photo: Tor Dam Eskildsen)
The robot enters the water through a hole in the ice. It is made of a material that can withstand considerable temperature fluctuations and protect the electronics in cold underwater conditions. It is steered from the surface by a standard X-box controller. (Photo: Tor Dam Eskildsen)
Good data quality depends on the robot being able to take measurements at exactly the same places under the ice over time. So what do you do when the ice is too thick for the GPS signals to penetrate? DeepFreeze is equipped with digital cameras that look through the cold, clear water towards two light sticks in the ice. The information is then sent to a computer that calculates the number of pixels between the two sticks and thereby the exact position of the robot. (Photo: Tor Dam Eskildsen)

Underwater robot provides new opportunities for polar research

Two engineering students have built an underwater robot that can analyse algae conditions under the Antarctic sea ice. This provides completely new opportunities for polar research, and the robot has just successfully completed its first scientific expedition to Greenland.

Team AU ready for the Shell Eco-marathon

The countdown has begun for this year’s world championship in ultra-energy-efficient vehicles. After two years of intensive development work, Aarhus University (AU) will now enter an ultra-efficient eco-car in the Shell Eco-marathon, which kicks off in London in June. The aim is to drive almost 9000 kilometres on the equivalent energy of one litre…

A single calculation can result in up to several thousand different combinations of wrong answers. Engineering students are behind a new app that can spot what a child has done wrong in less than a second. (Photo: Red Raccoon)

New app teaches children to count correctly

A new mathematics app is a hit in Denmark. It spots children’s weak points when they are doing mathematical exercises and explains where they are going wrong.
