Have you ever stamp on a cockroach , only to lift your human foot and see the microbe scurry off ? That horrify un - stomp - ability may really someday relieve lifespan . researcher have create elastic , roach - inspire saving robots that can squeeze through fling . They describe their invention in an upcoming theme in theProceedings of the National Academy of Sciences .
cockroach may be unpopular with most of us , but they ’re all the rage inside the University of California - Berkeley’sPoly - PEDALlab , where biologists and engineers uncover the secrets of animal motion . Researchers there see robotic possibilities in a gecko ’s sticky footpad , a crab ’s jointed legs , and the astonishingly resilient consistency of the cockroach .
Robert Full , head of the Poly - pedal point lab , has been watching cockroach for more than 25 years . We can thank Full for the disturbing find that cockroaches can run on two legs , and that they can make speeds of almost five fundament per second . All together , now : Thanks , Dr. Full .
" insect are the most successful animate being on Earth , ” Fullsaid in a press release . “ Because they intrude nearly everywhere , we should look to them for breathing in as to how to make a golem that can do the same . "

With that boost , Full ’s student Kaushik Jayaram design an experimentation to figure out how cockroaches manage to continue moving , even while they ’re being squelch . Jayaram sent cockroaches running through a short , transparent tunnel while taping them with a gamey - speed camera .
He recover that the bugs could press through the tunnel even when it was little than the smallest part of the cockroach . “ They ’re about half an column inch tall when they run freely , ” Jayaram said in the press release , “ but can squelch their organic structure to one - one-tenth of an inch — the height of two heap pennies . " The roach could also stand firm up to 900 times their own body weight without being injure . Even when the bugs were so tight they could not move their legs , they somehow kept move .
Slowing down the high-pitched - fastness motion-picture show revealed that when their metrical foot are unavailable , cockroaches flash forward using the spines on their legs . We might be grossed out by this information , but like his wise man , Jayaram was inspire .
" They have to habituate different consistency parts to move in these spaces , because their leg and foot are not orientate to run properly , " Jayaram continued in the press instruction . " But they are still able of generating the large forces necessary for locomotion , which blew my judgment . "
The resultant role of this judgment - blowing was the compressible robot with articulated mechanics , or CRAM , a modest , bug - mold bot capped with a flexile plastic casing . Jayaram and his sketch conscientious objector - authors created a bot that couldsmush downto half its height in society to squirm through small spaces .
Here ’s a video from Berkeley featuring the investigator ' tests with springy cockroaches and CRAM show off its abilities . If you ’re squeamish about circle , start at 01:21 to see the bot in action .
The CRAM is still in its prototype stage , but Jayaram , Full , and their fellow worker already have big plans for its future tense .
" In the consequence of an earthquake , first responder need to know if an area of rubble is static and good , but the challenge is , most golem ca n’t get into dust , " Full explained in the press release . " But if there are lots of cracks and vents and conduits , you’re able to imagine just shed a swarm of these robots in to locate survivor and safe entranceway degree for first responders . "
The next sentence you detect cockroach competition for your late - dark snack , you might desire to swap your sleeveless stomp for a small high-pitched - five . Because you just never know — that roach , or at least its bot cousin-german , might economize your life some day .
