Innovative Mars rovers 'swim' through the sand

Phys · · 479 words · By Julius Maximilian University

Researchers at the University of Würzburg, in collaboration with other German institutions, have developed a Mars rover wheel design inspired by the locomotion of the sandfish lizard. The design aims to improve mobility on granular surfaces by mimicking the animal's 'swimming' motion to reduce slipping and sinking.
