What is ROACH2
ROACH2 is our second attempt to build a rover that can drive on surfaces in weightlessness using electroadhesion. With this experiment we want to show that this technology is suitable for the demanding environment of weightlessness and vacuum. Our experiment consists of two components that are built into a sounding rocket. The first component is our autonomous rover with electroadhesion. The second component is an obstacle parkour which our rover is to master. Of course, there are also some sensors and cameras installed, so that the experiment can be better evaluated afterwards.
Motivation and reason for the project
REXUS/BEXUS is an international student programme in cooperation between the German Aerospace Center (DLR) and the Swedish National Space Administration (SNSA). It is designed as a competition and offers students the opportunity to conduct their own ideas as technical experiments under conditions similar to those in space. These include the influence of space radiation or the behaviour under reduced gravity. The experiments can be carried out either on a nearly six-metre-long rocket (REXUS), which reaches the peak of its flight path in up to 100 kilometres, or using a so-called stratospheric balloon (BEXUS), which can reach an altitude of up to 35 kilometres in free flight.Throughout the entire project, the German student teams will be supervised by DLR Space Management in Bonn, and will thus learn about the complete process of a space project, from the idea itself to the publication of the results.
