Tsis ntev los no, ib tug ntse, stretch-tau thiab rhiab heev tshiab software sensor tau raug qhia, uas yuav tsum tau los ua daim tawv nqaij tshiab ntawm neeg hlau, nws tuaj txog coj cov kev hloov tshiab ntawm cov tsos ntawm robots thiab robotic prosthetics thiab lwm yam kev siv, qhov no yog los ntawm ib qho ntawm cov neeg ua haujlwm ntxov tshaj plaws ntawm cov neeg hlau tsim tawm Honda thiab University of British Columbia koom ua ke tsim cov khoom tshiab.
Thaum cov tawv nqaij sensor no tau siv rau ntawm ceg tawv ntawm cov pob qij txha lossis cov neeg hlau, nws tuaj yeem muab cov neeg hlau nrog kov rhiab heev thiab yoog raws, kom lub tshuab tuaj yeem ua cov haujlwm uas yav dhau los nyuaj ua tiav, xws li yooj yim khaws cov txiv hmab txiv ntoo, thiab vim tias kov cov yam ntxwv ntawm software sensor zoo ib yam li tib neeg cov tawv nqaij, Pab ua kom muaj kev sib cuam tshuam ntawm cov neeg hlau thiab tib neeg muaj kev nyab xeeb thiab muaj tseeb dua.
Lub Tsev Kawm Ntawv Qib Siab British Columbia, lub npe hu ua UBC, yog ib qho ntawm cov teb chaws Europe cov thawj coj hauv kev tshawb fawb Robotics, thiab pab pawg UBC tau tsim cov thev naus laus zis hauv kev koom tes nrog Frontier Robotics ntawm Honda Research Institute. Honda tau tsim kho tshiab hauv kev ua haujlwm ntawm tib neeg cov neeg hlau txij li xyoo 1980s thiab tau tsim cov neeg hlau nto moo ASIMO, nrog rau lwm cov khoom siv taug kev thiab cov neeg hlau Honda Avatar uas tshwm sim.
Lub sensor yog ua los ntawm silicone roj hmab, cov khoom siv feem ntau siv hauv cov yeeb yaj kiab tshwj xeeb los ua cov tawv nqaij textures, thiab nws cov qauv tsim tshwj xeeb tso cai rau nws khoov thiab wrinkle zoo li tib neeg cov tawv nqaij. Lub sensor siv lub zog hluav taws xob tsis muaj zog kom paub cov khoom, txawm tias nyob deb, zoo li lub vijtsam kov. Tab sis tsis zoo li ib txwm kov cov ntxaij vab tshaus, lub sensor no yog mos heev thiab muaj peev xwm ntes lub zog ntawm cov khoom nkag mus thiab raws nws qhov chaw. Qhov kev sib xyaw tshwj xeeb no yog qhov tsim nyog kom paub cov neeg hlau uas cuam tshuam nrog tib neeg.
Lub sensor siv qhov sib npaug thiab qhov sib txawv ntawm cov teeb liab los ntawm plaub lub deformable capacitors kom paub qhov txawv ntawm qhov qub thiab shear rog siv ib txhij. Lub crosstalk ntawm shear force thiab ib txwm quab yuam yog tsawg dua 2.5%, thiab crosstalk ntawm shear axis yog tsawg dua 10%. Qhov kev ntxhov siab ib txwm thiab kev ntxhov siab shear rhiab heev yog 0.49 kPa thiab 0.31 kPa, feem, thiab qhov kev daws teeb meem tsawg kawg yog 40 μm. Tsis tas li ntawd, cov ntiv tes sib thooj tuaj yeem kuaj pom txog li 15 mm.
Ryusuke Ishizaki, ib tug ntawm cov thawj coj ntawm txoj kev tshawb no thiab ib tug thawj coj engineer ntawm Frontier, hais tias: "Dr. Madden's lab ntawm UBC muaj kev txawj ntse nyob rau hauv lub teb ntawm saj zawg zog sensors, thiab peb zoo siab los koom tes nrog lawv los tsim no tactile sensor. technology rau robots. "
Cov kws tshawb fawb tau sau tseg tias lub sensor tshiab yog qhov yooj yim rau kev tsim khoom, yog li nws tuaj yeem ua tau yooj yim scaled kom npog thaj chaw loj thiab ua kom loj. Dr. Madden tau hais ntxiv tias kev txhim kho txuas ntxiv ntawm cov sensors thiab cov cuab yeej ntse tau ua rau cov neeg hlau muaj zog dua thiab muaj tseeb, thiab tib neeg tuaj yeem koom tes thiab cuam tshuam nrog lawv ntau dua.
Txawm li cas los xij, software sensors tuaj yeem ua tau ntau dua li qhov ntawd, raws li Dr. Madden hais tias: "Muaj 100 npaug ntawm cov ntsiab lus ntawm tib neeg cov tawv nqaij ntau dua li peb cov thev naus laus zis tam sim no, ua rau nws yooj yim dua rau cov neeg hlau ua haujlwm ntau dua, xws li teeb pom kev sib tw. los yog xaws." Raws li cov sensors tau los ze zog rau cov yam ntxwv ntawm tib neeg cov tawv nqaij thiab tseem tuaj yeem kuaj xyuas qhov kub thiab kev puas tsuaj, cov neeg hlau yuav tsum tau ntse dua txog kev nkag siab cov sensors tsom rau thiab yuav ua li cas teb. Kev txhim kho ntawm cov sensors thiab kev txawj ntse txawj ntse yuav tsum mus koom tes. "
