University of Würzburg Develops Mars Rover With Curved Wheels for 1 Vast Valles Marineris Mission

University of Würzburg researchers built and tested a bio-inspired Mars rover whose curved wheels mimic the Sahara sandfish, helping it move stably through sand and outperform other navigation methods.
Valles Marineris—the huge Martian rift valley targeted by DLR's VaMEx project—is hard to survey because dunes, slopes and uneven ground can trap conventional rovers, yet scientists want to search the region for liquid water and possible life.
Tests with DLR researchers in Bremen, the German Research Center for Artificial Intelligence and the University of Bremen showed stable motion on sand, while also highlighting needed improvements on mixed terrain.
The team is now refining software and control strategies to better handle slippage, sinking and wheel-terrain interaction, aiming for more adaptable mobility across Martian dune fields beyond Valles Marineris.

When will these revolutionary sand-swimming rovers actually get their chance to explore the Red Planet?
Will autonomous robot swarms be the key to finally uncovering signs of life within Mars' Grand Canyon?
Revolutionizing Mars Exploration: Bio-Inspired Rovers and Swarm Robotics in the VaMEx Valles Marineris Mission
Overview
Exploring Mars is challenging because its surface is covered with sand, gravel, and steep slopes, making it hard for traditional rovers to move efficiently. To solve this, researchers have developed a new Mars rover inspired by the sandfish lizard, which is known for moving easily across sand. The rover’s wheels mimic the lizard’s natural adaptations, giving it better traction and maneuverability. This bio-inspired design helps the rover travel over loose, granular surfaces without getting stuck or losing stability, marking a new and promising direction for planetary mobility and exploration.
