Watch this bio-inspired Mars rover idea ‘swim’ by sand on curved wheels (video)

A novel method to scouting the sand dunes of Mars is the Valles Marineris Explorer – or VaMEx. VaMEx is a undertaking of the German Space Agency on the German Aerospace Center (DLR). The objective of the initiative is to blueprint an autonomous, heterogeneous robotic swarm for exploring Valles Marineris on Mars — heralded because the “Grand Canyon” on the Red Planet.

Valles Marineris is a gigantic rift valley system on Mars that scientists wish to scour for traces of liquid water, which can exist in sheltered niches and function an habitat for doable life. But the area is tough to analyze attributable to its topography, which poses challenges for robotic surveying.

But the VaMEx crew is exploring mixtures of driving, strolling, and flying methods to leverage what every idea brings to the desk by way of collectively investigating a big space with various environmental traits. One distinctive method the crew is exploring is a Mars rover that’s outfitted with creative curved wheels, which, just like the ft of a desert lizard, can “swim” by sand.

A University of Würzburg analysis group has picked up on the sandfish’s manner of locomotion, adopting and adapting that motion right into a Mars rover that reportedly outperforms different methods of navigating throughout sand.

Collaborating with DLR researchers in Bremen, Germany, University of Würzburg specialists have designed rover wheels that imitate the sandfish mobility traits and interplay with the bottom, producing each longitudinal and lateral forces. That motion leaves sinusoidal, or S-shaped tracks within the sand.
