Disemba 8 – Abacwaningi base-University of California, eSanta Barbara (UC Santa Barbara) babonise ubuchwepheshe obusha bokubonisa ocwaningweni lwakamuva olushicilelwe kumagazini i-Science Robotics: izithombe eziguquguqukayo ezizivezayo azibonakali nje kuphela kodwa futhi ziyabonakala ngokomzimba. Ucwaningo lwethula ubuso obuncane kakhulu be-optoelectronic haptic obumbozwe ngama-pixels esikali samamilimitha; uma kukhanyiswa ama-pulse amafushane okukhanya okuveziwe, la ma-pixel ayaqhuma ukuze akhe amaqhubu athintayo angazwakala ngokuthinta.
Lo msebenzi waqala ngo-2021 ngenxa yombuzo olula obuzwe nguSolwazi uYon Visell wase-UC Santa Barbara: Ingabe ukukhanya okusetshenziselwa ukuveza izithombe nakho kungadala impendulo yomshini enamandla ngokwanele ukuba ibonwe ngezandla zabantu? Ngemva konyaka wokwenza amamodeli kanye nemizamo eminingi ye-prototype ehlulekile, uMax Linnander, umcwaningi eyunivesithi, wathuthukisa ngempumelelo idivayisi yokuqala yobufakazi bomqondo ekupheleni kuka-2022. Iqhutshwa kuphela ukukhanya okuvela ku-laser encane ye-diode futhi ingenazo izingxenye ze-elekthronikhi ezifakiwe, le divayisi ingakhiqiza ama-pulse acacile, abonakalayo lapho ethintwa.

Kuyaqondakala ukuthi ukwakheka okuphelele kokubonisa okuchazwe kulolu cwaningo kwakhelwe phezu kwale mpumelelo. Iphikseli ngayinye iqukethe ifilimu encane yobuso, umgodi womoya omncane ngaphansi kwayo, kanye nefilimu ye-graphite elengayo. Uma ivezwa ekukhanyeni, ifilimu ye-graphite imunca amandla okukhanya futhi iwaguqule ngokushesha abe ukushisa, okwenza umoya ongaphansi kwefilimu wande futhi usunduze ubuso phezulu nge-millimeter eyodwa. Lokhu kuphakama kokuguquguquka kwanele ukuthi abasebenzisi bakwazi ukuthola amaphikseli ngamanye ngokunembile ngeminwe yabo.
Njengoba umsebe we-laser ofanayo unikeza amandla kanye nokubhekisa amaphikseli, lonke iphaneli alidingi izintambo zangaphakathi. Uhlelo lokuskena olusheshayo lungashesha ludlule ku-pixel array, lusebenze amaphikseli ngamunye ngamunye ukuze lukhiqize izithombe ezibukwayo nezithintayo eziqhubekayo.
Ithimba locwaningo okwamanje liphumelele ukwakha uhlu oluqukethe amaphikseli angaphezu kuka-1,500 aqondene nawo ngokuzimela, impumelelo enkulu uma kuqhathaniswa nezibonisi ze-haptic zangaphambilini ezazilwela ukulinganisela ubuningi bamaphikseli, isivinini sokuphendula, kanye nobukhulu bokufuduka. Isikhathi salo sokuphendula sisukela kuma-millisecond angu-2 kuya kwangu-100, esanele ukukhiqiza kabusha ama-contour abushelelezi, izimo, kanye namaphethini abalingiswa. Ezivivinyweni zomsebenzisi, ababambiqhaza bakwazile ukulandelela ngokunembile izinto ezihambayo, ukuhlukanisa izakhiwo zendawo, kanye nokubona ulwazi lwesikhathi olwakhiwe ukusebenza okulandelanayo kwamaphikseli.
Abacwaningi baphawula ukuthi ngenxa yohlelo lokufaka amakheli olubonakalayo, ubuchwepheshe bunikeza ukusabalala okuhle kakhulu. Ama-array amakhulu angaqhutshwa ama-laser okuskena amancane avame ukusetshenziswa kumaphrojektha esimanje. Baphinde babone izinhlelo zokusebenza ezahlukahlukene, njengezixhumi zezimoto zomuntu nomshini ezilingisa izilawuli zomzimba, kanye nemibhalo ye-elekthronikhi noma imidwebo eshintsha ngokuguquguqukayo ngaphansi kwesandla somfundi.
Nakuba kusesesigabeni se-prototype, lolu cwaningo luphawula okokuqala amandla okukhanya eguqulwa ngqo abe ukuguqulwa kwemishini ngesisombululo esiphezulu. Ngakho-ke ithimba le-UC Santa Barbara livule indlela entsha: izibonisi ze-haptic zesikhathi esizayo zizoziphatha njengezibonisi ezibonakalayo zendabuko, zethule ulwazi ngefomethi engabonwa ngamehlo ngasikhathi sinye futhi ihlolwe ngeminwe.
