Thaum cov tub ntxhais kawm cov thawj coj ntawm Northeastern University Mars Rover Team txiav txim siab tias lawv yuav mus koom rau hauv qhov kev sib tw lub caij ntuj no Canadian International Rover Challenge, lawv xav tias nws yuav yog qhov kev xyaum zoo tshaj li lwm yam.
Lawv tsis cia siab tias yuav yeej qhov kev sib tw. Txawm li cas los xij, qhov ntawd yog qhov tshwm sim.
Pab pawg Northeastern coj lub tsev kub lub hli tas los, ntaus McMaster University rau qhov chaw sab saum toj nrog tus qhab nia 237.71 rau McMaster's 137.13.
Brooke Chalmers, tus tub ntxhais kawm xyoo thib peb ntawm Northeastern thiab kev koom ua ke ntawm cov thawj coj thiab software ua haujlwm rau pawg Mars rover tau hais tias "Nws zoo nkauj heev rau peb ntawm pab pawg neeg coj ncaj ncees." "Nws yeej xav zoo li txhua teev uas peb muab tso rau hauv lub lis piam dhau los tau them tawm hauv txoj kev."
Nws yog thawj qhov kev sib tw yeej rau lub club muaj rau xyoo, uas yog tsim los ntawm cov tub ntxhais kawm kawm computer science, engineering, thiab life science.
Pab neeg hauv tsev kawm ntawv txog li 50 tus tub ntxhais kawm tau ua haujlwm nyuaj hauv kev txhim kho thiab rov ua haujlwm ntawm nws qhov tseeb robotic rover: Watney, Mark V.
Los ntawm 50 kg (110 lb.), lub rover nta 5052 aluminium alloy chassis, rau 3D-luam nylon log, ib tug neeg hlau caj npab nrog kawg-ntawm-arm tooling (EOAT), lub neej-nrhiav module rau cov qauv sau, thiab 14 lub koob yees duab onboard.
Kev sib tw Canadian tau tawg ua plaub qhov kev sib tw tsim los tso cov tub ntxhais kawm rovers los ntawm kev simulated ib puag ncig zoo ib yam li cov haujlwm uas lub rover yuav tau ua kom tiav thaum nyob hauv Mars. Txhua qhov kev sib tw tau suav nrog qhov ntsuas 100-point.
Piv txwv li, hauv Arm Dexterity Challenge, cov tub ntxhais kawm tau ua haujlwm los tswj lub rover tus neeg hlau caj npab kom rov qab muaj zog rau lub chaw pw hav zoov. Qhov kev sib tw muaj feem cuam tshuam rau kev taug qab cov neeg hlau los ntawm plaub lub chaw tswj hwm qhov twg cov neeg hlau caj npab yuav tsum nias khawm thiab hloov pauv, piav qhia Jason Kobrin, tus tub ntxhais kawm plaub xyoos ntawm Northeastern thiab cov neeg ua haujlwm kho tshuab ua haujlwm rau pawg Mars rover.
Pab pawg Northeastern redesigns neeg hlau caj npab rau lub zog
Ntawm plaub pawg koom nrog hauv kev sib tw, Northeastern tau qhab nia siab tshaj plaws rau kev sib tw, nrog rau 49.49 cov qhab nia.
Kobrin tau hais tias pab pawg tau siv xyoo dhau los ua kom tiav kev kho dua tshiab ntawm tus neeg hlau caj npab, uas tau siv los ua ib qho ntawm cov rover cov ntsiab lus tsis muaj zog thaum kev sib tw dhau los. Tam sim no nws yog ib qho ntawm lub zog loj tshaj plaws ntawm rover. Tus neeg hlau caj npab muaj rau qib kev ywj pheej thiab tuaj yeem nqa tau txog li 10 kg (22 lb.).
"Yuav kom txhim kho qhov ntawd, peb rov tsim kho peb txhais caj npab xyoo no kom siv cov motors zoo dua thiab tswj tau yooj yim dua," nws hais.
Nws yog los ntawm kev koom nrog hauv cov kev sib tw no thiab dhau los ntawm kev sim tsis tu ncua qhov twg pab pawg tuaj yeem nqaim ntawm lub rover qhov tsis txaus thiab txhim kho nws lub peev xwm, Kobrin tau hais. Los ntawm kev ua haujlwm ntawm lub rover, cov tub ntxhais kawm kuj tau txais lub sijhawm los txhim kho lawv cov kev txawj ntse.
"Txhua lub lis piam, nws yog kev txhim kho tas mus li," nws sau tseg. "Txawm hais tias nws ntxiv ib feem tshiab ntawm software code [lossis] txawm tias tsim lub mount tshiab rau peb lub koob yees duab, txhua qhov kev txhim kho me me ua rau muaj qhov sib txawv loj."
"Rau txhua tus tuaj yeem tsim thiab tsim cov neeg hlau no kom ua haujlwm tau zoo tab sis kuj tseem tuaj yeem tswj tau nws nyob rau hauv cov xwm txheej siab thiab ua kom tau raws li cov hom phiaj peb tab tom nrhiav kom ncav cuag, tsuas yog qhov ua tau zoo heev," Kobrin ntxiv.
Pab pawg tau xav tias qhov kev tshwm sim ob hnub nyob rau hauv Niagara Falls, Ontario, yuav yog qhov zoo tshaj plaws los sim tawm lub peev xwm ntawm lub tshuab ua ntej pab pawg tau koom nrog hauv University Rover Challenge (URC). URC yog Mars Society tus thawj coj Mars rover kev sib tw tub ntxhais kawm nyob rau ntawm Mars Desert Research Center sab nraum Hanksville, Utah.
Kev sib tw URC yog lub kaus mom qub rau pab pawg, tau koom nrog kev sib tw hauv 2019, 2022, thiab 2023. Kev sib tw tau raug tshem tawm hauv 2020 thiab 2021 vim tias muaj kev sib kis.
"Peb tau mus rau hauv qhov kev sib tw no xav, 'OK, peb yuav siv qhov no los ua lub sijhawm los npaj rau URC. Peb yuav sim cov khoom kom paub tseeb tias nws ua haujlwm tau zoo," "Chalmers hais.
Qhov chaw nyuaj thiab pab pawg zoo siab
Pab pawg tau pom nws qhov zoo tshaj plaws thaum lub caij ntuj no Transversal Challenge, nrog rau qhov ua tiav ntawm 84.72 cov ntsiab lus. Rau qhov kev sib tw, lub rover yuav tsum dov los ntawm treacherous thiab tsis sib xws struts thaum zam obstacles.
Chalmers hais tias "Txhua qhov kev sib tw muaj feem cuam tshuam nrog qee qhov ntawm lub rover tsav tsheb nyob ib puag ncig thiab txav mus rau qhov nyuaj, tab sis qhov kev sib tw no tau tsom mus rau qhov ntawd," Chalmers hais.
Nrog rau qhov yeej tag nrho, Chalmers tau hais tias nws cia siab tias cov tswv cuab tshiab yuav zoo siab koom nrog.
"Feem ntau cov neeg hauv pab pawg tau tham txog qhov no nrog lawv cov phooj ywg thiab tsev neeg thiab tham txog qhov peb tab tom ua, uas yog qhov zoo heev," nws hais. "Kuv paub ob peb tus phooj ywg tau nthuav tawm kev txaus siab los koom nrog pab pawg txij li ntawd. Nws zoo siab heev uas muaj qee yam los tham txog thiab muaj qee yam los qhia rau txhua qhov kev siv zog uas peb muab rau hauv."
