A rising number of companies and organisations are researching space technologies supporting extraterrestrial life. Whether Moon or Mars, the number of rocket launches is increasing year by year. The majority of National Space Agencies are planning exploration missions with fully autonomous robots, which can conduct several studies about the composition of the lunar dust. Especially the extraction of oxygen from the moon dust, called regolith, is of great interest. Also many other projects are planned. But the initial step of all processes is often forgotten: it is the supply of raw materials. Therefore, a closer look at the possibilities of excavating and conveying regolith has been taken. The research ranges from concept development, calculation to simulation and designing a robotic system.
