Nrog qee qhov luam tawm 3D thiab ob peb yam khoom pheej yig, koj tuaj yeem tsim me me, xov tooj tswj tsheb LEGO.

Rau qhov project no kuv yuav siv:

  • ESP32 microcontroller (Adafruit Feather ESP32 lossis TTGO sib npaug ntawm qhov no)
  • 2 x N20 lub cev muaj zog
  • 1 x 18650 lithium roj teeb
  • 2 x Pololu DRV8835 lub cev muaj zog tsav tsheb (txawm hais tias tsuas yog ib tus xav tau, qhov thib ob yog rau kev nthuav dav yav tom ntej)
  • ib qho kev cai PCB los tuav DRV8835 lub tshuab tsav tsheb
  • ntau qhov 3D luam tawm (Kuv tsis muaj lub tshuab luam ntawv 3D - yog li kuv siv 3DHubs rau qhov kev pabcuam no)
  • LEGO - Cov txheej txheem thev naus laus zis thiab ob peb lwm daim

Nov yog qhov qhib qhov tsim tawm. Txhua qhov software, khoos phis tawj hluav taws xob thiab ntu 3D luam tawm muaj rau koj rub tawm/hloov kho/siv/lwm yam.

LEGO® yog lub cim lag luam ntawm LEGO Group ntawm cov tuam txhab uas tsis txhawb nqa, tso cai lossis lees paub qhov chaw no.

Kauj Ruam 1: Cov Khoom Siv Hluav Taws Xob

Kuv tau muaj kev cai PCB luam tawm ua "tus nqa khoom" rau DRV8835 cov tsav tsheb tsav. Koj tuaj yeem tsuas yog siv cov xov hlau hloov qhov no, tab sis nws yuav tsis zoo li. Kuv siv PCBWAY los ua PCB kev tsim khoom.

Txuas ntawm no yog Gerber cov ntaub ntawv yog tias koj xav kom koj tus kheej PCBs luam tawm, lossis Eagle cov ntaub ntawv yog tias koj xav hloov kho qhov tsim!

Kuv tab tom siv rau "N20" lub cev muaj zog. Koj tuaj yeem nrhiav cov no tau yooj yim ntawm EBay/AliExpress, thiab lwm yam. Cov qauv uas kuv siv yog 6v, 300rpm, nrog 10mm shafts.

Lub tsev nyob lub cev muaj zog thiab qag adapter tau luam tawm 3D. Txuas nrog koj tuaj yeem pom cov ntaub ntawv STL. Kuv siv 3DHubs.com los luam cov no (luam tawm ntawm 100um).

Kauj Ruam 3: Lub Roj Teeb

Lub Roj Teeb Nrog

Tus tuav lub roj teeb kuj tseem yog 3D luam tawm, txawm hais tias koj tuaj yeem yooj yim siv tshem tawm lub txee roj teeb thiab muab qee cov LEGO cib/phaj rau nws.

Txuas nrog yog STL cov ntaub ntawv yog tias koj xav luam qhov no.

Kauj ruam 4: Software

ESP32 tab tom khiav lub web server. Qhov no ua haujlwm nplooj ntawv uas tso cai rau koj xa cov tswv yim tswj rov qab rau ESP32 ntawm WebSocket (li no nws yuav qis qis). Lub vev xaib yuav ua haujlwm kov ntau lossis nas nkag.

Koj tuaj yeem rub tawm qhov chaws rau txoj haujlwm no.

Kauj ruam 5: Tsim

Tam sim no txhua lub Cheebtsam ua haujlwm, nws yog lub sijhawm rau kev lom zem - siv koj lub tswv yim thiab tsim lub tsheb / neeg hlau.

Tus neeg tsav tsheb tuaj yeem tuav txog 4 DRV8835's uas txhais tau tias tag nrho ntawm 8 DC Motors tuaj yeem tsav, lossis 4 Stepper motors, lossis kev sib xyaw ntawm cov no …
