Traditionally, the robotic vehicles to be sent to other celestial bodies carry with them all the instruments and tools necessary for the mission. With this approach these units are built as unique. They are heavy, complex, costly and do not present any interchangeable parts that could be replaced in the event of permanent failure. However, for future missions, agencies, institutes and commercial companies have been developing robotics systems based on the concept of modular robotics. This new strategy becomes critical for planetary exploration because it is able to reduce load, costs and development time. ARCHES, the German Aerospace Center (DLR) multi-robot system project, is in line with this modern design methodology.
