This concluding part of ESA's ‘Analog-1’ project took place as part of a larger multi-agency, multi-rover campaign, organised by the DLR German Aerospace Center. The Autonomous Robotic Networks to Help Modern Societies, ARCHES, project probed the ability of autonomous robots to collaborate and share data on a networked basis.

ESA’s four-wheeled, two-armed Interact rover was built by the Agency's Human Robot Interaction Lab and modified for the rugged slopes of the volcano. This robot formed part of a team consisting of two DLR rovers – Lightweight Rover Units 1 and 2 – along with a fixed ‘lunar’ lander supplying WiFi and power to the rovers, plus a drone for surface mapping. The Karlsruhe Institute of Technology contributed the centipede-like Scout crawler, optimised for tough terrain, which could also serve as a relay between Interact and the lander, boosting its effective area of operations.
