Named for its supposed resemblance to a crouching hyena, the Hyanide is designed to run on a flexible rubber tread that spans the machine’s entire underside.
So if any part of the bottom is touching the ground, the Hyanide should be able to move, no matter how deep the quagmire, no matter how rough the terrain. The tank-like tread consists of 77 identical segments — each made from hard plastic covered with tire rubber — held together by Kevlar rope.
