The easiness but excellent mobility of snakes makes them an ideal creature for roboticists to emulate , but it also yields robots that are downright creepy . make things uncollectible , investigator at the University of California , Santa Barbara , and Georgia Tech , have made asnakebot that can tunnel undergroundso we ’ll never see it coming .
To date , we ’ve managed to engineer robots and self-directed tool that can handle almost any terrain , be it rolling across therocky surface of Mars , diving below the waves , soaring through the sky , or evendeftly tackling a escape of step . Where robots have yet to explore is underground . We ’re not talking about spelunking through a cavernous subterranean cave , but rather burrowing and forging their own course through sand and stain like countless of Mother Nature ’s creations do .
We ’ve seensnakebotsbefore , but theresearchers at UCSB and Georgia Techhave created a new design with several central upgrades that allow it to more easily grind through granular material all on its own . Unlike othersnakebots , this version is what ’s believe a soft consistency robot because , as the name implies , it forgoes rigid parts for flexile fabric that make it lighter and more adaptable because it can more well bend , twist , and contort its eubstance .

One of the biggest challenge of tunnel through any material is the rubbing created , and sustain to have the best it . So the researchers take in more inspiration from nature and copied the chemical mechanism plants use to dig up late into the territory by grow only from the gratuity , leaving the residual of the root stationary . The snakebot does the same thing , growing only from the end of the bot so the rest of its body does n’t actually move at all , eliminating a major source of friction . If you ’ve ever struggled to pull a stem out of the priming coat , it ’s because you ’re contend against the friction of its entire length abrading against the surrounding soil .
The snakebot ’s incessantly grow tip still requires a certain level of force to push sand and dirt out of its way while it compass , but the research squad once again found inspiration in nature to make this task easier for their bot . Like the southern gumption octopus which shoots a K of H2O into the sea level to relax sand so it can bury itself as a protective defense mechanism , the snakebot raise a bam of air ahead of it to create a fluidized version of Baroness Dudevant and ground that ’s easy to campaign through .
By combining a wedged - shape ‘ fountainhead ’ with a blast of air directed slimly downwards , the snakebot loosen the soil in advance of , and below it , to thin forces that course occur in granulose materials that tend to push larger object towards the Earth’s surface . It not only makes it easier for the snakebot to dig , but it also makes it easier to stay underground as it burrows .
Besides pass the world one more source of anxiety , the burrowing snakebot does have some authentically utilitarian applications , and not just afford the military machine of the world an autonomous weapon that can tunnel beneath wall , barbellate wire , fields of land mine , and other obstacles . While the rovers we ’ve place to Mars are equipped with drills , there ’s far more to be learn about neighboring planets by digging much inscrutable beneath their surfaces . It could even be a utilitarian dick for archeology , letting scientist explore a site without stimulate to disturb what ’s on the surface until something ask to be unearthed .
