Zida zofewa zamaloboti ofewa a m'badwo wotsatira ScienceDaily

Maloboti ofewa omwe amayendetsedwa ndi madzi opanikizidwa amatha kufufuza malo atsopano ndikulumikizana ndi zinthu zosalimba m'njira zomwe maloboti okhazikika sangathe. Tsopano, ofufuza a Harvard John A. Paulson School of Engineering ndi Applied Sciences (SEAS) apanga ma valve ofewa a magetsi kuti azitha kuyendetsa magetsi opangira magetsi. , ndi zina. "Mayendedwe okhwima amasiku ano amachepetsa kwambiri kusinthasintha ndi kuyenda kwa maloboti ofewa oyendetsedwa ndi madzi," adatero Robert J. Wood, Harry Lewis wa SEAS ndi Marlyn McGrath Professor of Engineering and Applied Science ndi wolemba wamkulu wa pepala. "Pano, tapanga mavavu ofewa, opepuka owongolera ma hydraulic actuators, opatsa mwayi wowongolera mofewa pamaloboti ofewa amtsogolo." Mavavu ofewa si atsopano, koma mpaka pano palibe amene akwanitsa kukwaniritsa kuthamanga kapena kuyenda komwe kumafunidwa ndi ma hydraulic actuators ambiri omwe alipo. kachulukidwe kamphamvu kwambiri, ndi opepuka ndipo amatha kugwira ntchito mazana a masauzande a nthawi. Gululo linaphatikiza ma actuators a dielectric elastomer awa ndi njira zofewa kuti apange mavavu ofewa owongolera madzimadzi. "Mavavu ofewa awa amakhala ndi nthawi yoyankha mwachangu ndipo amatha kuwongolera kuthamanga kwamadzi ndikuyenda kuti akwaniritse zofuna za ma hydraulic actuators," adatero Siyi Xu, wophunzira womaliza maphunziro ku SEAS komanso wolemba woyamba wa pepala. ndi ma hydraulic actuators ang'onoang'ono okhala ndi ma voliyumu amkati kuyambira mazana a ma microliters mpaka makumi a milliliters." Pogwiritsa ntchito valavu yofewa ya DEA, ofufuzawo adawonetsa kuwongolera kwa ma hydraulic actuators amitundu yosiyanasiyana ndipo adapeza kuwongolera kodziyimira pawokha kwa ma activator angapo oyendetsedwa ndi gwero limodzi lokakamiza. "Vavu iyi ya DEA yaying'ono komanso yopepuka imathandizira kuwongolera zamagetsi zomwe sizinachitikepo kale za ma hydraulic actuators, kuwonetsa kuthekera koyendetsa maloboti oyendetsedwa ndi madzi ofewa mtsogolo," adatero Xu. Phunziroli linalembedwa ndi Yufeng Chen, Nak-Seung Patrick Hyun ndi Kaitlyn Becker.Anathandizidwa ndi mphoto CMMI-1830291 kuchokera ku National Science Foundation ndi National Robotic Program. Zida zoperekedwa ndi Harvard John A. Paulson School of Engineering and Applied Sciences.Nkhani yoyambirira yolembedwa ndi Leah Burrows.Zindikirani: Zolemba zitha kusinthidwa malinga ndi kalembedwe ndi kutalika. Pezani nkhani zaposachedwa za sayansi ndi kalata yamakalata yaulere ya ScienceDaily, yosinthidwa tsiku ndi tsiku komanso sabata iliyonse.Kapena onani nkhani zosinthidwa ola lililonse mu owerenga anu a RSS: Tiuzeni zomwe mukuganiza za ScienceDaily - timalandila ndemanga zabwino ndi zoyipa. Khalani ndi mafunso aliwonse okhudza kugwiritsa ntchito tsamba?funso?
