The American engineers developed the computer algorithm imitating behavior of an ant in tunnels of an ant hill. Scientists claim that problems, which the ant faces, don’t differ from what the rescue robot will face for search of people in blockages.
Those problems, which ants face, in principle, don’t differ from with what the robot should cope. So, they need to move very quickly, and thus to make stable and safe passes. If the scientists want to create the rescue robot – “digger”, they can borrow the basic principles of its work at ants.
The scientists work some years over creation of the robots using practices of wildlife in the work. So, in April 2013, they created the robot – the “turtle”, capable to go on sand not worse than the real reptiles. This time scientists reproduced algorithms, which fiery ants use during ant hill construction.
Scientists got some hundred ants and landed them in almost flat glass vessel filled with the earth. The soil in this “sandbox” was non-uniform. So, part banks were filled with rough fragments of a matter, and the other with smallest sand. Engineers tracked actions of insects within a day, tracing changes in strategy of construction of tunnels.
It appeared that tunnel width, instead of properties of the soil, was defining factor at their laying. In all cases diameter of a tunnel didn’t exceed 3-4 millimeters that corresponds to the sizes of a body of an insect. The similar geometry of “street” of an ant hill isn’t casual. At “earthquakes” which scientists arranged, ants clung short moustaches to narrow walls of pass and didn’t fall on a vessel bottom. In the following works engineers will try to create the rescue robot on the basis of strategy, which are used by ants.
