Concepts presented @ CDR

Our basic concept is a team-based implementation of two tethered devices: a wheeled rover providing overview sight, power supply and a communication bridge and a legged climber that will fullfill the main tasks as descend into the crater, sample some soil specimen, climb up the slope and return the samples to the landing site.

A fully covered second prototype of the legged robot ALF will be constructed and manufactured soon. The higher torsional stiffness allows more accurate control for reliable walking abilities and the cover protects the interior against sand and dust.

As a sampling mechanism, we are suggesting a drilling device (Archimedes screw) to draw the granular specimen. It will be located at the front and the suction procedure will happen in an animal-like way.
