"Kuti uone kugona kwakazara kwezvifambiso zvemagetsi izvi, unoda hungwaru hunodzora hurongwa hunovandudza kusimba kwavo uye kunyanya kusimba kwavo pakurwisa kwakasiyana," anodaro Soon-Jo Chung, Bren Purofesa weKudzora uye Dynamical Systems kuCaltech uye. Senior Research Scientist kuJPL, iyo Caltech inotonga yeNASA. "Takagadzira hurongwa hwekutadza-kushivirira hwakakosha kune kuchengetedzwa-kwakakosha kuzvitonga masisitimu, uye inounza zano rema sensors ekuona chero kutadza kushandisa muchina kudzidza uye kugadzirisa nzira dzekudzora."
Multiple Rotor Zvinoreva Mazhinji Anogoneka Mapoinzi ekukundikana
Mainjiniya ari kuvaka idzi ndege dzemagetsi dzakasanganiswa dzine mapropeller akawanda, kana rotor, muchikamu chedundancy: Kana rotor imwe ikatadza, mota dzinoshanda dzakakwana dzinosara kuti dzirambe dziri mhepo. Zvisinei, kuderedza simba rinodiwa kuita ndege pakati penzvimbo dzomumaguta—soti, mamaira 10 kana kuti 20—ngarava yacho inodawo mapapiro akasimba. Kuva nemarotor nemapapiro, zvisinei, zvinogadzira mapoinzi akawanda ekutadza kukwanisika mundege imwe neimwe. Uye izvo zvinosiya mainjiniya aine mubvunzo wekuti anoona sei kana chimwe chinhu chisina kumira zvakanaka nechero chikamu chemotokari.
Mainjiniya anogona kusanganisira masensa erotor yega yega, asi kunyangwe izvo zvingave zvisina kukwana, anodaro Chung. Semuyenzaniso, ndege ine rotor mapfumbamwe ingada masensa anopfuura mapfumbamwe, sezvo rotor imwe neimwe ingada imwe sensor kuti ione kutadza murotor chimiro, imwe kuona kana mota yayo ikamira kumhanya, uye imwezve kunyevera kana chiratidzo chewaya dambudziko. zvinoitika. "Unogona kuzopedzisira wava nemasensa akaparadzirwa zvakanyanya," anodaro Chung, asi izvo zvingadhura, zvakaoma kutarisira, uye zvaizowedzera huremu hwendege. Iwo masensa pachawo anogona kutadzawo.
NeNFFT, boka raChung rakaronga imwe nzira, itsva nzira. Kuvaka pamusoro kuedza kwekare, boka racho rakagadzira nzira yekudzidza yakadzama isingagoni kungopindura kumhepo ine simba chete asiwo kuona, pakubhururuka, apo ndege yakatambura kukundikana. Iyo sisitimu inosanganisira neural network iyo yakafanodzidziswa pane chaiyo-yehupenyu data data uye yobva yadzidza uye kuchinjika munguva chaiyo zvichienderana nenhamba shoma yekuchinja paramita, kusanganisira fungidziro yekuti inoshanda sei imwe neimwe rotor mundege iri kushanda chero ipi zvayo. nguva.
"Izvi hazvidi mamwe ma sensors kana Hardware yekuona kukanganisa uye kuzivikanwa," anodaro Chung. "Isu tinongoona maitiro endege - maitiro ayo uye chinzvimbo sebasa renguva. Kana ndege ichibva panzvimbo yainoda kubva panzvimbo A kuenda kunongedzo B, NFFT inogona kuona kuti pane chakashata uye yoshandisa ruzivo rwainayo kuripa chikanganiso ichocho.
Uye kururamisa kunoitika nekukurumidza zvakanyanya-pasi pesekondi. "Kubhururuka nendege, unogona kunyatsonzwa musiyano unoitwa neNFFT mukuchengetedza kudzoreka kwendege kana mota ikatadza," anodaro Staff Scientist Matthew Anderson, munyori wepepa uye mutyairi wendege akabatsira kuita bvunzo dzendege. "Iyo chaiyo-nguva yekudzora dhizaini inoita kuti iite sekunge hapana chachinja, kunyangwe iwe uchangomira imwe mota yako."
Kuunza Virtual Sensors
Iyo NFFT nzira inotsamira pane chaiyo-nguva yekudzora masaini uye algorithms kuona kuti kukundikana kuri kupi, saka Chung anoti inogona kupa chero mhando yemotokari zvakanyanya emahara ma sensors kuona matambudziko. Dare racho rakanyanya kuedza nzira yekudzora pamotokari dzomuchadenga dzavari kugadzira, kusanganisira Autonomous Flying Ambulance, motokari yemagetsi yakasanganiswa yakagadzirirwa kutakura vanhu vakakuvara kana vanorwara kuzvipatara nokukurumidza. Asi boka raChung rakaedza nzira yakafanana-yekushivirira yekudzora pamotokari dzepasi uye ine hurongwa hwekushandisa NFFT kuzvikepe.
