+
+This year at the Enrich robotics hackathon, we explored a part of the nuclear power plant in Austria that was inaccessible in previous competitions.
+The objective was to localize and map multiple radioactive probes under conditions of varying difficulty.
+Challenges included sections that were dimly lit or with no illumination at all, weak or no wifi condition, and an open hole the robot could fall into.
+
+We successfully mapped the entire accessible area and, for the first time, autonomously created a 3D map of the radioactivity with a new approach based on Gaussian Processes and won the award for best radioactivity map for the fourth time.
+Another highlight was a film crew from Galileo that followed us for two days.
+You can view the resulting clip in German [here](https://www.galileo.tv/video/tschuess-atomkraft-so-funktioniert-der-akw-rueckbau/) starting from 04:50.
