Elizabeth – the robosnake- was created by a team including researchers from many universities. In fact, it has an interesting story. Before it was built, some team members made a trip to Arizona, where captured six adult sidewinders and packed up 440 pounds of Arizona sand. Hosted at Atlanta Zoo, their movements on flat and inclined sandy surfaces was recorded with high-speed video camera. The next step was to examine the videos extracting the model for sidewinders’ movements. The conclusion was that the sidewinders were moving their body segments in wave-like motions vertically as well as horizontally, based on the condition of the surface they were traversing. Finally, the robosnake was projected and created. Such robots can fit into places that people and machinery can’t otherwise access. It can be particularly used in search and rescue operations.
