As part of the 1st RST Hackathon, a mobile robot (TurtleBot) and a drone were used to simulate a delivery scenario using autonomous robot systems, which could become a reality in a few years' time. 24 participants competed against each other in six teams and developed interesting and innovative solutions. The presentation to a panel of experts on Sunday consisted of a presentation on the approach developed and a live demonstration. In addition to the theoretical approach itself, the accuracy of the drone's landing approaches and the delivery time were evaluated. It was particularly pleasing that all teams, regardless of their subsequent ranking, were able to collect many moments of success and enjoyed the competition as a whole. As this was the first event of its kind at our department, it wasn't just the participants who learned a lot - the organizers also gained important experience and insights that will certainly benefit the next hackathon.
