The bot itself is a 10cm long strip of silicone rubber moved by embedded shape memory alloy coils. For its sensor suite, the GoQBot uses 5 infrared emitters paired with high-speed 3D tracking systems to figure out where it’s going.
This robot looks cool, but it may also have a more practical purpose. The researchers hope that their caterpillar robot design could be used in search and rescue operations. Lead author Huai-Ti Lin from the Department of Biology, Tufts University, added. "Due to the increased speed and range, limbless crawling robots with ballistic rolling capability could be deployed more generally at a disaster site such as a tsunami aftermath. The robot can wheel to a debris field and wiggle into the danger for us."
