Snakes and snake-like robots show how sidewinders conquer sandy slopes

Researchers studied sidewinder snakes to understand the unique motion they use to climb sandy slopes. Shown (l-r) are Dan Goldman of Georgia Tech, Hamid Marvi of Carnegie Mellon and Joe Mendelson of Zoo Atlanta.The amazing ability of sidewinder snakes to quickly climb sandy slopes was once something biologists only vaguely understood and roboticists only dreamed of replicating. By studying the snakes in a...
