This study deals with the design and the experimental test of a prototype of soil sampler to be equipped on team DIANA’s rover ARDITO, a vehicle designed for competitions related to human assistance during Mars exploration. The project was carried out in collaboration with team DIANA, a student team from Politecnico di Torino involved in the design and production of rovers, with the purpose of joining the World Rover Challenge series. A brief analysis of the main systems available for Earth and Mars soil sampling was first carried out to quantify the parameters mainly affecting the quality of the sampling and the effective feasibility on Mars soil.
