The sandfish lizard strikes very effectively by way of the sands of the Sahara desert, and never surprisingly, it does not use wheels to take action. Scientists have now copied the reptile’s swimming movement in an experimental Mars rover that outperforms others in sandy soil.
The prototype rover is a part of the German House Company’s VaMEx (Valles Marineris Explorer) program, which is an initiative aimed toward creating swarms of driving, strolling and flying robots designed to discover Mars’ huge Valles Marineris valley.
And sure, the rover does the truth is have wheels … however they are not regular ones.
The sandfish lizard (Scincus scincus) “swims” by way of the sand by undulating its physique backward and forward, which is a movement that the College of Würzburg’s Prof. Marco Schmidt got down to replicate within the car’s distinctive wheels. These wheels do nonetheless roll, however additionally they wiggle, for lack of a greater phrase.
Sandfish-lizard-inspired Mars rover
Developed in partnership with the College of Bremen, the wheels have been initially heavier and narrower than comparable standard pneumatic wheels. This meant they’d an inconvenient tendency to sink into the sand and to slide in opposition to it, hampering the rover’s motion.
That drawback was remedied by making them each lighter and wider, growing their flotation whereas additionally decreasing slippage. Consequently, when traversing unfastened sand, the rover ended up outperforming comparable autos that have been geared up with standard wheels.

Plans now name for additional refinements to be made to the wheels, to boost their efficiency on blended terrain.
