Argonaut is a variant of Taurob tracker and the first fully autonomous, mobile inspection robot for oil and gas plants. In 2018, Hector competed at the World Robot Summit in Tokyo in the Plant Disaster Prevention Challenge and won 1st place. The research team of Stryk has been building the German Rescue Robotics Centre since 2018. Campuses The university, with 164 Buildings and an area of property of , is concentrated at three campuses, Inner City, Lichtwiese and Botanical Garden. But individual facilities can be found in other parts of Darmstadt and in Griesheim, a neighboring town. Inner City Campus This campus lies very central in Darmstadt and is easily reachable by tram and bus from every part of the city. The departments located here are Electrical Engineering and Information Technology (FB18), History and Social Sciences (FB2), Human Sciences (FB3), Computer Science (FB20), Mathematics (FB4), Physics (FB5) and Law and Economics (FB1). Campus Lichtwiese The Lichtwiese lies in the eastern part of Darmstadt. It is reachable by bus and a nearby train station. The departments located here are Architecture (FB15), Civil Engineering and Geodesy (FB13), Chemistry (FB7), Mechanical Engineering (FB16) and Materials and Earth Sciences (FB11). Botanical garden The Botanical Garden of TU Darmstadt is located near the Lichtwiese Campus and the Department of Biology (FB10) is located here as well. With additional buildings of the Department of the Materials and Earth Sciences (FB11) and parts of the faculty of Chemical Engineering and Biotechnology of the Darmstadt University of Applied Sciences (h_da) it makes for an additional smaller campus. Griesheim Since 2005, TU Darmstadt owns the August Euler Airfield, Germany's oldest airfield, for scientific purposes. It is named after its founder August Euler, a pioneer aviator. The airfield is not only used to start planes, but also to conduct research on topics where wide spaces are needed, for example driver assistance systems and automotive lighting are being tested here. Located near the airfield are the wind tunnels of TU Darmstadt. Internationality With 18% (2017), the percentage of international students at TU Darmstadt is clearly higher than the average of German universities of 13% (2017/18). TU Darmstadt maintains partnership agreements with over 300 universities in 53 countries world-wide, which enable students to come to TU Darmstadt and to go abroad within their course
