This study explores the innovative use of tumbleweed-inspired rovers to navigate the challenging terrains of Mars, specifically the geologically rich region of Dao Vallis. The research leverages a dynamic model of individual tumbleweed rovers in a stochastic simulation, showcasing how these rovers, driven by wind forces, can autonomously disperse over extensive distances. This approach addresses the logistical challenges of accessing remote geological sites by minimizing control systems, thus enhancing Mars exploration efficiency.
