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

Hauv Cov Lus Qhia no peb yuav ua tus neeg hlau (ntau dua li lub tsheb RC) uas yog tswj los ntawm lub suab piv txwv li Kev Paub Lub Suab. Ua ntej kuv pib muab cov ntsiab lus ntxiv rau koj ib tus yuav tsum paub tias qhov no yog Kev Paub Lub Suab thiab tsis yog Kev Paub Hais Lus uas txhais tau tias tus tswj hwm tsis nkag siab qhov koj tab tom tham. Txoj haujlwm no siv tus lej kaum tsev VR3 tus qauv uas xa cov ntaub ntawv mus rau 2 thiab 3 tus lej digital ntawm Arduino. Nws kuj tseem muaj HC-SR04 sensor rau hom autopilot. Qhov VRBOT no ua haujlwm raws li hauv qab no:

1. Ua ntej kuv qhia tus qauv nrog qee cov lus txib tshwj xeeb xws li "FORWARD", "BACKWARD" thiab lwm yam.
2. Tshaj li los ntawm kev siv cov hloov pauv yooj yim tsim kuv ua haujlwm Arduino zoo li yog tias nws (VR module) tau txais tib cov lus txib nws muab arduino tus nqi uas piv nrog cov txiaj ntsig uas twb muaj lawm hauv lub cim xeeb.
3. Yog tias qhov xwm txheej poob tseeb dua li cov txheej txheem tshwj xeeb tau ua tiav.
4. xws li FORWARD ua rau VRBOT txav mus rau tom ntej.

Muaj tsuas yog 4 cov lus txib hauv txoj haujlwm no tab sis koj tuaj yeem muaj txog 80 cov lus txib. Cov 4 yog

1. "Mus Ntxiv"
2. "Rov qab"
3. "Tig"
4. "Autopilot" (cov lus txib no ua rau lub ntsuas hluav taws xob thiab VRBOT dhau los ua qhov teeb meem zam kev siv neeg hlau, txoj haujlwm no muaj qee qhov tsis xws luag vim qhov tsis raug ntawm HC-SR04 module)

Tsis txhob hnov qab nyem qhov pov npav. Thiab ua tsaug rau koj nyeem kuv cov lus qhia.

Yog tias koj tab tom ua ib qho dhau qhov nws xav tias ib tus muaj kev paub pib ntawm Arduino thiab nws IDE yooj yim.

Kuv tab tom ua qhov muab me me (los ntawm qhov kuv txhais tau tias tsuas yog 2) ntawm pawg thawj coj saib arduino. Kuv tab tom xav txog txoj haujlwm loj thiab xaj 3 arduino's (tab sis tom qab ntawd kuv rho tawm lub tswv yim thiab ua qhov no nrog tsuas yog ib qho Arduino) yog li kuv xav khaws ib qho nrog kuv tus kheej thiab muab tawm mus. Txhawm rau nkag tsuas yog tawm tswv yim VRBOT. (thiab tsis txhob hnov qab pov npav/nyiam/sau npe tab sis qhov ntawd tsis yog ib feem ntawm kev muab khoom plig).

Nov yog cov vis dis aus luv luv (thov txim rau kev kho tsis zoo)

Kauj Ruam 1: Qhov:

Ntseeg kuv cov kauj ruam no yog qhov tsim nyog tiag tiag vim tias yog koj tab tom ua VRBOT rau koj tus kheej dua li koj paub zoo tias koj yuav xav tau lub cav, lub log, roj teeb, Arduino. Tab sis cov uas tau paub yuav siv sijhawm me ntsis los nyeem cov theem no.

• Arduino (Ib leeg ntawm ib qho DIY ntse tsheb lossis neeg hlau peb mam tham txog qhov no tom qab)
• Lub suab lees paub lub suab (Ib qho, tab sis VR V3 tau pom zoo)
• Li-ion cells
• Cov Motors (Yog tias tsim kom muaj qhov loj me siv qis RPM motors)
• Log
• L293D tsav tsheb (ic lossis module)
• HC-SR04 (yog tias koj tsis xav kom koj tus neeg hlau tsoo nws lub taub hau tiv thaiv phab ntsa)
• Dawb LED's (tsav tsheb thaum hmo ntuj yam tsis muaj teeb pom kev zoo heev)

Cov no yog qhov tseem ceeb qee cov cuab yeej yuav pab tau:

1. Soldering Hlau
2. Kub nplaum
3. Txiv neej rau Poj niam cov xov hlau (uas yog qhov lawv hu nws)
4. Hlau Strippers
5. Daim kab xev
6. Txiv neej Pins
7. PCB
8. Cov nab kuab

Tsis txhob hnov qab yuav lossis ua lub chassis

Qhov ntawd yog nws!

Kauj ruam 2: Chassis

Txhawm rau ua Chassis (txawm hais tias lub cev zoo li lub plank ntau dua li lub chassis) koj tuaj yeem siv cov khoom uas koj nyiam nrog, Kuv tau siv hardboard vim tias nws yooj yim rau txiav tab sis nws muab rigidity.

Qhov twg txhua qhov khoom siv tau muab tso rau kuv tau siv 2 txheej ntawm hardboard kom nws tsis khoov. Txiav lub hardboard thiab muab nws cov duab uas koj xav tau.

Tam sim no pleev xim nws!

Kauj Ruam 3: Ua L293D

Yog tias koj tau coj tus qauv zoo teeb tsa nws thiab hla cov kauj ruam no.

Thiab yog tias koj muaj IC thiab cov cuab yeej tshwj xeeb ua raws cov kauj ruam no.

Cov txheej txheem ntawm L293D IC tau muab rau hauv daim duab koj tsuas yog yuav tsum tau siv cov xov hlau kom tsim nyog.

Yog xav paub ntxiv mus ntawm no:

Nyem qhov no!

Kauj Ruam 4: Txuas Cov Tsav Tsheb thiab L293D

Kaw cov motors lossis txuas lawv nrog rivets ntawm lub hardboard tom qab ntawd nrog txiv neej rau poj niam xov hlau koom nrog lawv rau L293D IC. Kaw IC nrog daim kab xev ob tog

TSWV YIM: Yog tias koj tab tom ua ib tus ntawm koj tus kheej tsis txhob siv lub chassis tsim no vim tias hauv qhov kev tsim no thaum ib tus tig lub neeg hlau dua li lub cav tsuas yog vim nws tig rov qab.

Txuas lub cav mus rau L293D ic raws li tau hais hauv cov txheej txheem hauv cov kauj ruam dhau los.

Kauj Ruam 5: Kev Paub Lub Suab

Qhov no yog cov kauj ruam tseem ceeb tshaj plaws. Ua ntej peb yuav ua qhov kev sib txuas tom qab kev ua haujlwm. Muaj ob txoj hauv kev ntawm cov kauj ruam no. Ua ntej suav nrog kev txuag ntawm 2D kab lus ntawm lub suab tshwj xeeb thiab qhov dav xws li kaw koj lub suab lossis kev qhia paub Lub Suab Kev lees paub lub suab. (Yog tias tshiab rau arduino dua li teeb tsa software xav tau rau arduino)

Kev Sib Txuas:

• TX pin of module --Arduino's DP2
• RX tus pin ntawm module --Arduino's DP3
• GND-NCO
• Vcc-+5 volt ntawm arduino

Tom qab ntawd mus rau (https://github.com/elechouse/VoiceRecognitionV3) txhawm rau rub tawm txhua lub tsev qiv ntawv thiab qauv piv txwv.

Tom qab ntawd xa [vr_sample_train] code thiab qhib Serial Monitor (nws yuav coj koj mus tom ntej) koj tuaj yeem hais lus ua lwm yam lus thiab ua cov lus tsim nyog raws li koj cov lus txib.

Tom qab ntawv rub tawm cov qauv coj ua piv txwv uas tig LED rau thaum koj hais kom nws.

Kauj Ruam 6: Programming Arduino

Kev Sib Txuas:

B/W arduino thiab motors

Cov motors tau txuas nrog L293D IC's thiab tus pin sensor ntawm L293D tau txuas nrog txoj hauv kev uas cov motors ntawm ib sab nyob hauv kev sib txuas sib txuas. (vim tias thaum nws tig ob lub cav rov qab thiab ob mus rau tom ntej). Yog li koj tsuas yog yuav tsum siv 4 tus pin ntawm arduino rau lub cev sib txuas txuas ntxiv ntawm nws tau sau hauv cov cai.

Digital Pin 2 & 3 tau tshwj tseg rau TX thiab RX pins ntawm tus qauv. 4, 5, 6, 7 yog rau lub cav. 9 thiab 10 yog rau cov ntsuas.

Ua ntej qhia koj tus qauv nrog cov lus txib (Txoj cai tuaj yeem nkag tau tsuas yog 4) hauv kev txiav txim piv txwv li kev tsheb nqaj hlau 1 dua li tsheb nqaj hlau 2.

Tshaj li rub tawm cov cai no uas ua cov hauv qab no:

• Tsiv mus tom ntej thaum mus tom ntej lossis hais kom ua no.0 yog ua tiav
• Tsiv rov qab thaum rov qab lossis hais kom ua tsis tau. 1 yog ua tiav
• Tig thaum tig hais kom ua tiav
• Tau dhau los ua ib qho khoom tiv thaiv neeg hlau thaum Autopilot hais kom ua tiav

Cov kev sib txuas thoob plaws cov lus qhia no yog raws li txoj cai yog tias koj xav tau koj tuaj yeem hloov qhov kev sib txuas los ntawm kev hloov pauv lawv hauv txoj cai.

Kauj Ruam 7: Txuas HC-SR04

HC-SR04 yog lub ntsuas ntsuas nrug deb deb uas tsis raug. Yog qhov no muaj nws tus kheej cov teeb meem yog li ntawd nws tau pom zoo kom yuav tus kim Ping sensor tab sis rau kev pheej yig (cov lus xav tau) kuv tau siv HC-SR04.

hauv qab no yog kev sib txuas ntawm HC-SR04 thiab arduino

Teeb 9

Echo 10

Upload tib cov cai tam sim no. Thiab tam sim no thaum koj hais 'Autopilot' hais kom ua nws yuav dhau los ua ib qho khoom siv zam tus neeg hlau.

Kauj Ruam 8: Ua Lub Roj Teeb

Txuas ob lub Lithium Ion hlwb hauv koob thiab nws ua tiav!

Koj tuaj yeem muab daim npog rau nws lossis txhua yam uas koj nyiam.

Nco tseg: Li-Ion cells yuav tsum tsis txhob them nrog lub roj teeb zoo ib txwm siv lub tswb nkaus xwb.

Txuas nws mus rau arduino's Vin thiab L293d's Vcc. (nrog cov nab kuab)

Kauj Ruam 9: Ntxiv Teeb

Muab qhov muag rau koj tus neeg hlau yuav tsis nyuaj li tab sis rau cov neeg tshiab txuas lub LED rau lub tshuab nrog 220-1K resistor (nyob ntawm xim). Yog li paub thaum nws mus rau pem hauv ntej LED lub teeb.

Kauj Ruam 10: Ua Tsaug

Ua tsaug rau koj nyeem. Kuv yuav muaj lub luag haujlwm ntau dua yog tias koj pov npav rau kuv. Thiab yog tias ua ib qho rau koj tus kheej qhia rau kuv paub. Zoo Siab Ua!
