Lizard-inspired wiggly wheels let Mars rover swim through sand

Lizard-inspired wiggly wheels let Mars rover swim through sand

The sandfish lizard moves very efficiently through the sands of the Sahara desert, and not surprisingly, it doesn't use wheels to do so. Scientists have now copied the reptile's swimming motion in an experimental Mars rover that outperforms others in sandy soil.

Why this matters
Why now

Ongoing advancements in robotics and biomimicry are continually pushing the boundaries of autonomous exploration, driven by the desire for more resilient and efficient systems in challenging environments.

Why it’s important

This development represents a significant step in improving robotic mobility in difficult terrains, crucial for space exploration and potentially terrestrial applications, impacting mission success and operational efficiency.

What changes

Mars rovers could become significantly more capable of traversing diverse and challenging sandy landscapes, reducing the risk of getting stuck and expanding exploration zones.

Winners
  • · Space agencies
  • · Robotics researchers
  • · Planetary exploration missions
Losers
  • · Traditional wheel-driven rover designs
  • · Missions constrained by limited sandy terrain navigation
Second-order effects
Direct

Mars missions will benefit from enhanced mobility and broader exploration capabilities in sandy regions.

Second

The biomimicry principles could be adapted for terrestrial robotics in desert, agricultural, or disaster relief scenarios.

Third

Increased success in planetary exploration may accelerate funding and public interest in space science and robotics research.
