Cov khoom muag muag rau tiam tom ntej mos robots ScienceDaily

Mos robots powered by pressurized fluids can explore the new areas and interact with ilv objects in the traditional rigid robots can can't.Tab sis kev tsim cov neeg hlau mos mos tseem yog ib qho kev sib tw vim tias ntau yam uas xav tau los ua kom muaj zog cov cuab yeej no inherently nruj. Tam sim no, cov kws tshawb fawb ntawm Harvard John A. Paulson Tsev Kawm Ntawv ntawm Engineering thiab Applied Sciences (SEAS) tau tsim hluav taws xob mos li qub los tswj hydraulic mos actuators.Cov li qub no tuaj yeem siv rau hauv kev pab thiab kho cov cuab yeej, bionic mos robots, mos grippers, phais neeg hlau. , thiab ntau dua. "Hnub no cov txheej txheem kev tswj hwm nruj heev txwv qhov kev hloov pauv thiab kev txav mus los ntawm cov kua dej uas tau tsav cov neeg hlau," said Robert J. Wood, SEAS 'Harry Lewis thiab Marlyn McGrath cov xibfwb ntawm Engineering thiab Applied Science thiab daim ntawv tus kws sau ntawv laus. "Ntawm no, peb tau tsim. mos, lub teeb yuag li qub rau kev tswj cov hydraulic actuators mos, muab qhov muaj peev xwm ntawm kev tswj hwm ntawm lub rooj tsavxwm rau cov kua dej tom ntej. Cov li qub tsis yog tshiab, tab sis tam sim no tsis muaj leej twg tuaj yeem ua tiav qhov siab lossis ntws los ntawm ntau cov hydraulic actuators uas twb muaj lawm. Kom kov yeej cov kev txwv no, pab pawg tau tsim tshiab electrodynamic dynamic dielectric elastomer actuators (DEAs).Cov mos actuators muaj ultra- Lub zog hluav taws xob siab, yog lub teeb yuag thiab tuaj yeem ua ntau pua txhiab lub sijhawm.Qhov pab pawg ua si nrog cov neeg muag muag muag muag rau cov khoom mos. Siyi Xu, tus tub ntxhais kawm tiav ntawm SEAS thiab thawj tus kws sau ntawv tau hais tias "Cov valve no muaj lub sijhawm teb ceev thiab tuaj yeem tswj cov kua dej siab thiab ntws kom tau raws li qhov xav tau ntawm hydraulic actuators," said Siyi Xu, tus kawm tiav ntawm SEAS thiab thawj tus kws sau ntawv. thiab me me hydraulic actuators nrog cov ntim sab hauv xws li ntau pua microliters mus rau kaum milliliters." Siv lub DEA soft valve, cov kws tshawb fawb tau qhia txog kev tswj hwm ntawm hydraulic actuators ntawm ntau qhov sib txawv thiab ua tiav kev tswj hwm ywj pheej ntawm ntau tus actuators uas tau tsav los ntawm ib qho chaw siab. "Qhov no compact thiab lub teeb yuag DEA valve enables unprecedented hluav taws xob tswj ntawm hydraulic actuators, qhia lub peev xwm rau on-board motion tswj ntawm mos-kua-driven robots nyob rau hauv lub neej yav tom ntej," Xu hais. Txoj kev tshawb no yog co-sau los ntawm Yufeng Chen, Nak-Seung Patrick Hyun thiab Kaitlyn Becker.Nws tau txais kev txhawb nqa los ntawm khoom plig CMMI-1830291 los ntawm National Science Foundation thiab National Robotics Program.
