EV 3
LEGO MINDSTORMS Kev Kawm Ntawv EV3 yog ua tau nrog Lego Technic qhov chaw. Qhov no txhais tau hais tias lub platform tuaj yeem siv los tsim ntau yam thiab txawm tias tsim qauv zoo kawg li, los ntawm cov "tsheb" yooj yim thiab "s robots tes" mus rau txoj kev conveyors lossis txawm tias "Rubik's cube solvers." Zoo li txhua qhov Lego Technic teeb tuaj yeem siv los ua qhov chaw ntawm cov haujlwm, thiab yuav tsis muaj teeb meem hloov cov khoom seem puas. Yog lawm, lawv tsis zoo li kev lim hiam li qub Soviet aluminium siv cov khoom siv, tab sis nyob rau hauv kev xyaum lawv tig tawm los ua kom muaj zog dua li cov khoom siv hlau. Tsawg kawg hauv kuv phau ntawv sau, uas tau pib xyoo 1993, tsis tau pom ib qho tawg lawm.
MINDSTORMS Education EV3 Basic Educational Set los nrog 541 Lego Technic pieces. Koj tuaj yeem yuav khoom raws li cov peev txheej tshwj xeeb xws li (los yog laus dua 9648, ua rau NXT), lossis tsuas yog tus tsim qauv loj (2800 ntu) los yog (yuav luag 4000 ntu), thiab, tau ua si txaus nrog tus qauv tseem ceeb, siv nws ua "cib" rau kev sim cybernetic. Nyob rau hauv cov nqe lus ntawm ib daim, Lego yog heev ua ntej ntawm lwm cov teeb ntawm no - tsuas yog 3-5 rubles ib piece.
Zoo, yog tias ib tug neeg muaj cov khoom qub uas suav nrog kaum tawm txhiab qhov chaw, ces koj yuav tsis tas txhawj txog cov peev txheej txhua.
Cov duab thaij duab los ntawm cov kev pabcuam Brickset (ib qho kev sib tham sib tham rau cov tswv ntawm cov khoom siv Lego uas tso cai rau koj los sau ntau yam kev txheeb cais) los ntawm tus sau
Txawm li cas los xij, qhov no tsuas yog siv rau "passive" cov ntsiab lus xws li kab teeb, lub log lossis cov pins txuas. Sensors thiab effectors, ntawm chav kawm, yog kim dua, tab sis muaj ntau tshaj li txaus ntawm lawv nyob rau hauv cov khoom siv yooj yim. Mindstorms EV3 los ua tiav nrog peb lub cev muaj zog (ob lub zog loj dua thiab muaj zog dua thiab ib qho kev sib cog lus), ib khub ntawm kov sensors (ib hom "ntse" nyees khawm), ultrasonic, gyroscopic thiab xim sensors (nws tuaj yeem ua haujlwm hauv lub teeb sensor hom) . Ntxiv rau, kev sib raug zoo nrog cov sensors los ntawm tiam dhau los ntawm Lego Education robots - Mindstorms NXT (xws li, piv txwv li, lub suab nrov sensor) yog khaws cia.
Tab sis cia peb rov qab mus rau "smart cib", lub plawv ntawm lub system. Qhov no yog qhov tseeb qhov hnyav thiab voluminous "cib", nruab nrog 178x128 monochrome LCD npo (tsis yog cov ntawv qhia zaub mov nkaus xwb, tab sis kuj tseem muaj txhua hom duab kev cai thaum lub sijhawm ua haujlwm) nrog cov xim hloov pauv tau.
