Designing an all-terrain robot for search-and-rescue missions is an arduous task for scientists. The machine must be flexible enough to move over uneven surfaces, yet not so big that it’s restricted from tight spaces. It might also be required to climb slopes of varying inclines.

While studying and videotaping the movements of 20 different species at Zoo Atlanta, Marvi developed Scalybot 2, a robot that replicates rectilinear locomotion of snakes.

I remember reading about something similar to this a while back but this seems much more advanced. It's always impressive when engineers are able to directly draw from nature and incorporate it into their designs. The part that really peaked my interest was in relation to being able to articulate the scales to cope with different terrain. Unfortunately the picture in the article doesn't really show much detail, I’d really like to be able to see more.
