"Ukuze uqonde amandla apheleleyo ala maflaya ombane, udinga inkqubo yokulawula enengqondo ephucula ukomelela kwabo kwaye ngakumbi ukomelela kwabo ngokuchasene neentlobo ezahlukeneyo zeempazamo," utshilo uSoon-Jo Chung, uNjingalwazi weBren woLawulo kunye neeNkqubo zeDynamical eCaltech kunye INzululwazi yoPhando oluPhezulu kwi-JPL, elawulwa yiCaltech kwiNASA. "Siphuhlise inkqubo yokunyamezela iimpazamo ezibaluleke kakhulu kwiinkqubo ezizimeleyo zokhuseleko, kwaye yazisa umbono wezivamvo zokubona nakuphi na ukusilela kusetyenziswa umatshini wokufunda kunye neendlela zokulawula eziguquguqukayo."
IiRotors ezininzi zithetha amanqaku amaninzi anokuthi aphumelele
Iinjineli zakha ezi nqwelo-moya zombane ezixubeneyo ezineepropeller ezininzi, okanye iirotor, ngokuyinxenye ukuze zingasebenzi: Ukuba i-rotor enye iyasilela, iimotor ezisebenzayo ngokwaneleyo zihlala zihlala emoyeni. Noko ke, ukuze kuncitshiswe amandla afunekayo okwenza inqwelo-moya phakathi kweendawo ezisezidolophini—masithi, iikhilomitha ezili-10 okanye ezingama-20—inqanawa nayo ifuna amaphiko angagungqiyo. Ukuba nee-rotors kunye namaphiko, nangona kunjalo, kudala amanqaku amaninzi okusilela okunokwenzeka kwinqwelomoya nganye. Kwaye oko kushiya iinjineli nombuzo weyona ndlela ilungileyo yokubona xa kukho into engahambi kakuhle ngayo nayiphi na indawo yesithuthi.
Iinjineli zinokubandakanya abenzi boluvo kwi-rotor nganye, kodwa nokuba oko akunakukwanela, utshilo uChung. Ngokomzekelo, inqwelo-moya ene-rotors ezisithoba iya kufuna abenzi boluvo abangaphezu kwesithoba, kuba i-rotor nganye inokufuna inzwa enye ukubona ukusilela kwisakhiwo se-rotor, enye ibone ukuba imoto yayo iyeka ukusebenza, kwaye enye ilumkise xa kukho ingxaki yocingo. kwenzeka. UChung uthi: “Ekugqibeleni unokuba nenkqubo engasebenziyo kakhulu yezivamvo,” utsho uChung, kodwa oko bekuya kuba yindleko enkulu, kube nzima ukuyilawula, kwaye kuya kwandisa ubunzima benqwelo-moya. Izivamvo ngokwazo nazo zinokusilela.
NgeNFFT, iqela likaChung licebise enye indlela, inoveli. Ukwakha phezu iinzame zangaphambili, iqela liye laphuhlisa indlela yokufunda enzulu engakwaziyo ukuphendula kuphela kwimimoya enamandla kodwa ibone, xa ibhabha, xa inqwelo-moya iye yasilela. Inkqubo ibandakanya inethiwekhi ye-neural eqeqeshwe kwangaphambili kwidatha yendiza yokwenene kwaye ifunde kwaye ilungelelanise ngexesha lokwenyani ngokusekelwe kwinani eliqingqiweyo leeparamitha eziguqukayo, kubandakanywa noqikelelo lwendlela esebenzayo ngayo i-rotor nganye kwinqwelomoya esebenza kuyo nayiphi na into. ixesha.
"Oku akufuni naziphi na izinzwa ezongezelelweyo okanye i-hardware yokukhangela iimpazamo kunye nokuchongwa," utsho uChung. “Sijonga nje indlela inqwelo-moya eziphatha ngayo—isimo sayo sengqondo nesikhundla sayo njengomsebenzi wexesha. Ukuba inqwelo-moya iyatenxa kwindawo enqwenelekayo ukusuka kwindawo A ukuya kwindawo engu-B, iNFFT inokubona ukuba kukho undonakele ize isebenzise inkcazelo enayo ukubuyisela loo mpazamo.”
Kwaye ukulungiswa kwenzeka ngokukhawuleza okukhulu-ngaphantsi komzuzwana. “Ukubhabha kwinqwelo-moya, unokuwuva ngokwenene umahluko owenziwe yiNFFT ekugcineni ukulawuleka kwenqwelo-moya xa injini isilela,” utsho u-Staff Scientist uMatthew Anderson, umbhali wephepha nomqhubi wenqwelo-moya oncedise ekuqhubeni uvavanyo lokubhabha. "Uhlengahlengiso lolawulo lwexesha lokwenyani luyenza ivakale ngathi akukho nto itshintshileyo, nangona ukhe wayeka ukusebenza enye yeenjini zakho."
Ukwazisa iiSensors Virtual
Indlela ye-NFFT ixhomekeke kwimiqondiso yolawulo lwexesha lokwenyani kunye ne-algorithms ukufumanisa apho ukusilela, ngoko uChung uthi unokunika naluphi na uhlobo lwesithuthi ngokusisiseko simahla abenzi boluvo bokubona iingxaki. Iqela liye lavavanya ngokuyinhloko indlela yokulawula izithuthi ezihamba emoyeni eziphuhliswayo, kubandakanywa i-Ambulance ye-Autonomous Flying, isithuthi sombane esidibeneyo esilungiselelwe ukuthutha abantu abalimele okanye abagulayo ngokukhawuleza kwizibhedlele. Kodwa iqela likaChung livavanye indlela yokulawula impazamo efanayo kwizithuthi eziphantsi kwaye inezicwangciso zokusebenzisa iNFFT kwiinqanawa.
