Rau tib neeg, nrhiav ib lub hnab nyiaj poob faus rau hauv ib pawg ntawm cov khoom yog ncaj nraim -- peb tsuas tshem cov khoom ntawm pawg mus txog thaum peb pom lub hnab nyiaj. Tab sis rau ib tug neeg hlau, txoj haujlwm no suav nrog kev sib tham txog cov pawg thiab cov khoom hauv nws, uas ua rau muaj kev nyuaj siab heev.
MIT cov kws tshawb fawb yav dhau los tau ua kom pom lub caj npab neeg hlau uas sib txuas cov ntaub ntawv pom thiab xov tooj cua zaus (RF) cov cim kom pom cov khoom zais uas tau cim nrog RFID cim npe (uas cuam tshuam cov teeb liab xa los ntawm tus kav hlau txais xov). Txhawm rau txhim kho cov haujlwm ntawd, tam sim no lawv tau tsim ib txoj haujlwm tshiab uas tuaj yeem khaws tau txhua yam khoom faus rau hauv pawg. Ntev npaum li qee cov khoom hauv pawg muaj RFID cim npe, cov khoom lag luam tsis tas yuav tsum tau sau npe rau lub kaw lus kom rov qab tau nws.
Cov algorithms tom qab lub kaw lus, hu ua FuseBot, yog vim li cas txog qhov tshwm sim qhov chaw thiab kev taw qhia ntawm cov khoom hauv qab pawg. Tom qab ntawd FuseBot nrhiav txoj hauv kev zoo tshaj plaws los tshem tawm cov khoom thaiv thiab rho tawm cov khoom lag luam. Qhov laj thawj no tau ua rau FuseBot nrhiav cov khoom zais ntau dua li lub xeev-of-the-art robotics system, hauv ib nrab sijhawm.
Qhov kev nrawm no tuaj yeem pab tau tshwj xeeb hauv e-commerce warehouse. Tus neeg hlau ua haujlwm nrog kev ua haujlwm rov qab tuaj yeem pom cov khoom hauv pawg tsis tau txheeb xyuas tau zoo dua nrog FuseBot system, hais tias tus kws sau ntawv laus Fadel Adib, tus kws tshaj lij hauv Department of Electrical Engineering thiab Computer Science thiab tus thawj coj ntawm pab pawg Signal Kinetics hauv Media Lab.
"Dab tsi daim ntawv no qhia, thawj zaug, yog tias qhov tsuas yog muaj cov khoom siv RFID-tagged nyob rau hauv ib puag ncig ua rau nws yooj yim dua rau koj kom ua tiav lwm yam haujlwm zoo dua. Peb tuaj yeem ua qhov no vim peb ntxiv. multimodal laj thawj rau lub system -- FuseBot tuaj yeem xav txog ob qho tib si lub zeem muag thiab RF kom nkag siab txog ib pawg ntawm cov khoom, "Adib ntxiv.
Koom nrog Adib ntawm daim ntawv yog tus pab tshawb fawb Tara Boroushaki, uas yog tus thawj coj; Laura Dodds; thiab Nazis Naeem. Cov kev tshawb fawb yuav raug nthuav tawm ntawm Robotics: Science thiab Systems lub rooj sib tham.
Hom phiaj tag
Daim ntawv tshaj tawm kev lag luam tsis ntev los no qhia tau hais tias ntau dua 90 feem pua ntawm Asmeskas cov khw muag khoom tam sim no siv RFID cov cim npe, tab sis cov thev naus laus zis tsis yog thoob ntiaj teb, ua rau muaj xwm txheej uas tsuas yog qee yam khoom hauv pawg tau sau npe.
Qhov teeb meem no tau tshoov siab rau pab pawg tshawb fawb.
Nrog FuseBot, tus neeg hlau caj npab siv lub koob yees duab txuas nrog thiab RF kav hlau txais xov kom khaws cov khoom lag luam uas tsis muaj npe los ntawm pawg sib xyaw. Lub kaw lus scans pawg nrog nws lub koob yees duab los tsim 3D qauv ntawm ib puag ncig. Tib lub sijhawm, nws xa cov teeb liab los ntawm nws lub kav hlau txais xov los nrhiav RFID cim npe. Cov xov tooj cua no tuaj yeem dhau los ntawm cov khoom siv feem ntau, yog li tus neeg hlau tuaj yeem "pom" tob rau hauv pawg. Txij li thaum lub hom phiaj khoom tsis tau tagged, FuseBot paub cov khoom tsis tuaj yeem nyob ntawm qhov chaw tib yam li daim npav RFID.
Algorithms fuse cov ntaub ntawv no los hloov kho 3D qauv ntawm ib puag ncig thiab qhia txog qhov chaw muaj peev xwm ntawm cov khoom lag luam; tus neeg hlau paub nws qhov loj thiab zoo li cas. Tom qab ntawd cov txheej txheem vim li cas ntawm cov khoom hauv pawg thiab RFID tag qhov chaw los txiav txim seb yam khoom twg yuav tshem tawm, nrog rau lub hom phiaj ntawm kev nrhiav cov hom phiaj nrog qhov tsawg tshaj plaws txav.
Nws yog ib qho nyuaj rau muab qhov laj thawj no rau hauv qhov system, hais tias Boroushaki.
Tus neeg hlau tsis paub meej tias cov khoom tau taw qhia hauv qab pawg li cas, lossis yuav ua li cas cov khoom squishy yuav deformed los ntawm cov khoom hnyav dua nias rau ntawm nws. Nws kov yeej qhov kev sib tw no nrog qhov kev xav tsis zoo, siv qhov nws paub txog qhov loj thiab cov duab ntawm ib qho khoom thiab nws qhov chaw RFID tag los ua qauv rau 3D qhov chaw uas cov khoom yuav nyob.
Raws li nws tshem tawm cov khoom, nws kuj siv lub laj thawj los txiav txim siab yam khoom twg yuav "zoo tshaj" kom tshem tawm tom ntej.
"Yog tias kuv muab ib pawg ntawm cov khoom rau tib neeg los tshawb nrhiav, lawv feem ntau yuav tshem tawm cov khoom loj tshaj plaws ua ntej kom pom dab tsi hauv qab nws. Dab tsi tus neeg hlau ua zoo ib yam, tab sis nws kuj suav nrog cov ntaub ntawv RFID los txiav txim siab ntau dua. nug, 'Nws yuav nkag siab ntau npaum li cas ntawm pawg no yog tias nws tshem cov khoom no tawm ntawm qhov chaw?'" Booushaki hais.
Tom qab nws tshem tawm ib yam khoom, tus neeg hlau tau tshuaj xyuas pawg dua thiab siv cov ntaub ntawv tshiab los txhim kho nws lub tswv yim.
Rov qab tau cov txiaj ntsig
Qhov laj thawj no, nrog rau kev siv RF cov cim qhia, tau muab FuseBot ib qho ntug ntawm lub xeev-ntawm-tus-kos duab uas siv lub zeem muag nkaus xwb. Pab pawg tau khiav ntau dua 180 qhov kev sim sim siv cov caj npab thiab pawg neeg hlau tiag tiag nrog cov khoom siv hauv tsev, xws li cov khoom siv hauv chaw ua haujlwm, cov tsiaj txhu, thiab khaub ncaws. Lawv sib txawv qhov ntau thiab tsawg ntawm pawg thiab tus naj npawb ntawm RFID-tagged cov khoom hauv txhua pawg.
FuseBot tau rho tawm cov khoom lag luam ua tiav 95 feem pua ntawm lub sijhawm, piv rau 84 feem pua rau lwm cov neeg hlau. Nws ua tiav qhov no siv 40 feem pua tsawg dua, thiab nws tuaj yeem nrhiav thiab khaws cov khoom lag luam ntau dua ob zaug sai dua.
"Peb pom qhov kev txhim kho loj hauv qhov kev vam meej los ntawm kev koom nrog cov ntaub ntawv RF no. Nws kuj yog qhov zoo siab pom tias peb muaj peev xwm ua tau raws li qhov kev ua tau zoo ntawm peb cov txheej txheem dhau los, thiab tshaj nws nyob rau hauv cov xwm txheej uas cov khoom lag luam tsis muaj RFID. tag," Dodds hais.
FuseBot tuaj yeem siv rau hauv ntau qhov chaw vim tias cov software uas ua rau nws txoj kev xav nyuaj tuaj yeem siv rau hauv ib lub computer -- nws tsuas yog xav tau kev sib txuas lus nrog cov neeg hlau caj npab uas muaj lub koob yees duab thiab kav hlau txais xov, Boroushaki ntxiv.
Nyob rau yav tom ntej, cov kws tshawb fawb tab tom npaj yuav koom nrog ntau cov qauv hauv FuseBot kom nws ua tau zoo dua ntawm cov khoom deformable. Tsis tas li ntawd, lawv txaus siab tshawb nrhiav cov kev sib txawv, xws li lub caj npab robotic uas thawb cov khoom tawm ntawm txoj kev. Kev rov ua dua yav tom ntej ntawm lub kaw lus kuj tseem tuaj yeem siv nrog cov neeg hlau txawb uas tshawb nrhiav ntau pawg rau cov khoom ploj.
Txoj haujlwm no tau txais nyiaj, ib feem, los ntawm National Science Foundation, Sloan Research Fellowship, NTT DATA, Toppan, Toppan Forms, thiab MIT Media Lab.
