Robots could be a great support for astronauts on Mars missions. During AMADEE-24 this will be demonstrated by the three robots that belong to the experiment iROCS of the University of Applied Sciences Upper Austria and the University of Würzburg, Germany: The Intelligent Robot for Mapping Applications in 3D (Irma3D), robot Charlie, and the RTE (Rosen-bauer Technical Equipment) robot. With their technologies, they can help the analog astronauts both in the collection and analysis of rock samples and in the search for water. They will also map the terrain to identify possible obstacles. It is important for the analog astronauts to know where the terrain is accessible so they and the robots can carry out their tasks without restrictions. The robots can also be of great help with their ability to transport objects and power other devices.
