2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Nyob zoo txhua tus hauv phau ntawv qhia no muaj peev xwm. Kuv yuav qhia koj ib qib zuj zus cov lus qhia yuav ua li cas thiaj ua tau yooj yim rf (xov tooj cua zaus) RC (chaw taws teeb tswj) tsheb. Qhov no tuaj yeem ua los ntawm ib tus pib hauv ib teev

Kuv yuav tham txog kev ua haujlwm ntawm txhua qhov kev sib koom ua ke (IC) thiab cov qauv siv hauv cov neeg hlau no

Thiab tsis muaj qhov program xav tau rau kev ua tus bot no _ UPDATE_THE qhov hloov kho tshiab ntawm tus neeg hlau no muaj nyob ntawm no

Kauj ruam 1: Hloov kho VIDEO

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! UPDATE !!!!!!!!!!!!!!!!!!!!!!!!!!!

QHOV TSEEB VERSION NTAWM NO ROBOT YOG QHOV NO

Kauj ruam 2: QHOV VIDEO

Kauj Ruam 3: Cov Ntaub Ntawv Yuav Tsum Tau

• RF transmitter txais tus qauv
• pawg thawj coj saib x2
• HT12E encoder
• HT12d tus lej txiav txim

Kauj Ruam 8: Xaiv Koj Lub Cev

Xaiv lub cav yog ib qho tseem ceeb heev thiab nws tag nrho nyob ntawm seb hom neeg hlau (tsheb) koj tab tom ua

yog tias koj tab tom ua qhov me me siv 6v Bo lub cev muaj zog

Yog tias koj tab tom ua qhov loj dua uas nee nqa hnyav dua kaum siv lub 12v dc lub cev

Xaiv koj li RPM rau koj lub cav

RPM, uas sawv cev rau kev hloov pauv ib feeb, yog qhov ntau npaum li cas lub sijhawm ua haujlwm ntawm DC lub cev muaj zog ua tiav lub voj voog puv ib feeb. Lub voj voog puv puv yog thaum lub taub hau puv 360 °. Tus nqi 360 ° tig, lossis hloov pauv, lub cav ua hauv ib feeb yog nws tus nqi RPM

Koj yuav tsum tau ceev faj heev thaum xaiv lub rpm tsis txhob xaiv lub cav ntawm rpm siab dua vim tias kuv yuav nyuaj rau nws tswj hwm thiab nco ntsoov SPEED YOG TUS NEEG YUAV TSHWJ XEEB YUAV TSHWJ XEEB YUAV TSHWJ XEEB YUAV TSHWJ XEEB YUAV TSHWJ XEEB YUAV TSHWJ XEEB YOG TSEV KAWM NTAWV TORQUE

Kauj Ruam 9: Ua TSHUAJ

Ua lub chassis yog qhov yooj yim heev rau ua tsuas yog ob yam uas yuav tsum tau ua

1. tuav
2. tawv duab los qhia, daim ntoo lossis cov ntawv tuab rau ua lub hauv paus thiab qee qhov ntsia hlau

• Siv daim ntawv tso lub clamp rau nws kos rau qhov chaw drilling qhov rau ntxig cov ntsia hlau
• Laum qhov ntawm plaub ces kaum
• Ntsia lub clamp kom nruj
• Ntxig lub cav rau hauv lub clamp,
• Muab lub Circuit Court tso rau ntawm lub chassis txuas cov motors rau hauv Circuit Court
• Muab lub hwj chim 12v rau hauv Circuit

kom paub meej xyuas cov duab

Kauj Ruam 10: DEBUGGING OPTIONAL (Yog Muaj Teeb Meem Nrog Circuit)

Hauv ntu no peb yuav tham txog kev debug qhov Circuit

Ua ntej tshaj plaws tsis txhob npau taws cia li nyob twj ywm

rau kev debugging peb yuav faib cov Circuit hauv sib txawv

Ua ntej peb yuav debugging lub

L293D IB

Muab tus IC tso rau ntawm lub khob cij thiab muab 5v thiab Gnd rau IC thiab tom qab ntawd muab 12v rau tus pin 8. txuas lub pins ntawm cov motors mus rau 5v. multimeter. Yog tias nws tsis qhia dab tsi ces muaj teeb meem nrog koj tus tsav tsheb

Hwj chim muab

Feem ntau ntawm cov teeb meem tshwm sim hauv cov khoom siv hluav taws xob yog vim luv Circuit Court yog li txhawm rau txheeb xyuas lub zog tawm ntawm Circuit thiab siv lub multimeter los tshuaj xyuas seb puas muaj kev sib txuas ntawm Tsis Zoo thiab zoo

DECODER THIAB ENCODER

Rau kev debugging tus lej txiav txim siab thiab tus lej nkag IC txuas tus pin 7 ntawm HT12E rau tus pin 14 ntawm HT12D, Txuas cov laub khawm ntawm tus pin 10, 11, 12, 13 ntawm HT12E thiab txuas 4 leds ntawm tus pin 10, 11, 12, 13 ntawm tus txiav txim siab (txuas raws li ib tus Decoder thiab Encoder Debugging Circuit [daim duab 3]) Cov leds yuav tsum pom thaum hloov pauv

Yog tias koj tus bot tseem tsis ua haujlwm ces yuav muaj teeb meem nrog RF module peb tuaj yeem debug nws yog li hloov tus qauv.
