Hauv qhov kev qhia no peb yuav saib txog kev tsim ib qho kev pab cuam rau lub drone nrog lub suab tswj siv Node.js thiab Web hais lus API. Copter - Parrot ARDrone 2.0.
Peb nco qab: rau txhua tus neeg nyeem Habr - 10 ruble luv nqi thaum tso npe rau hauv ib chav kawm Skillbox siv Habr promo code.

Taw qhia
Drones yog amazing. Kuv yeej txaus siab ua si nrog kuv quad, thaij duab thiab yeeb yaj kiab, lossis tsuas yog muaj kev lom zem. Tab sis cov tsheb tsis muaj neeg tsav dav hlau (UAVs) yog siv rau ntau tshaj li kev lom zem xwb. Lawv ua hauj lwm hauv xinesmas, kawm glaciers, thiab siv los ntawm cov tub rog thiab cov neeg sawv cev ntawm kev ua liaj ua teb.
Hauv qhov kev qhia no peb yuav saib txog kev tsim cov kev pab cuam uas yuav tso cai rau koj los tswj lub drone. siv cov lus txib. Yog lawm, tus copter yuav ua qhov koj hais kom nws ua. Thaum kawg ntawm tsab xov xwm muaj qhov kev npaj ua tiav thiab yees duab ntawm UAV tswj.
Hlau
Peb xav tau cov hauv qab no:
- Parrot ARDrone 2.0;
- Ethernet cable;
- zoo microphone.
Kev txhim kho thiab kev tswj hwm yuav ua tiav ntawm chaw ua haujlwm nrog Windows / Mac / Ubuntu. Tus kheej, kuv tau ua haujlwm nrog Mac thiab Ubuntu 18.04.
Software
Download tau qhov tseeb version ntawm Node.js los ntawm .
Kuj xav tau .
To taub lub copter
Cia peb sim nkag siab tias Parrot ARDrone ua haujlwm li cas. Lub copter no muaj plaub lub cev muaj zog.
Cov motors tawm tsam ua haujlwm tib yam. Ib khub tig clockwise, lwm counterclockwise. Lub drone txav los ntawm kev hloov lub kaum sab xis ntawm inclination txheeb ze rau saum npoo ntawm lub ntiaj teb, hloov qhov ceev ntawm kev sib hloov ntawm lub motors thiab ob peb lwm yam maneuverable txav.
Raws li peb tuaj yeem pom hauv daim duab saum toj no, kev hloov pauv ntau yam ua rau muaj kev hloov pauv ntawm kev txav ntawm lub copter. Piv txwv li, txo qis los yog nce kev sib hloov ceev ntawm sab laug thiab txoj cai rotors tsim ib yob. Qhov no tso cai rau lub drone ya mus rau pem hauv ntej lossis rov qab.
Los ntawm kev hloov qhov ceev thiab kev taw qhia ntawm cov motors, peb teem lub kaum sab xis uas tso cai rau lub copter txav mus rau lwm cov lus qhia. Qhov tseeb, rau qhov project tam sim no tsis tas yuav kawm txog aerodynamics, koj tsuas yog yuav tsum nkag siab cov ntsiab lus tseem ceeb.
Yuav ua li cas Parrot ARDrone ua haujlwm
Lub drone yog Wi-Fi hotspot. Yuav kom tau txais thiab xa cov lus txib mus rau lub copter, koj yuav tsum txuas mus rau qhov no. Muaj ntau ntau yam kev siv uas tso cai rau koj los tswj quadcopters. Txhua yam zoo li no:
Thaum lub drone txuas nrog, qhib lub davhlau ya nyob twg thiab telnet 192.168.1.1 - qhov no yog tus IP copter. Rau Linux koj tuaj yeem siv .
Application architecture
Peb cov cai yuav muab faib ua cov nram qab no modules:
- tus neeg siv interface nrog kev hais lus API rau lub suab tshawb pom;
- lim cov lus txib thiab sib piv nrog tus qauv;
- xa cov lus txib mus rau lub drone;
- live video tshaj tawm.
API ua haujlwm tsuav yog muaj kev sib txuas hauv Is Taws Nem. Kom paub meej qhov no, peb ntxiv Ethernet kev twb kev txuas.
Nws yog lub sijhawm los tsim daim ntawv thov!
Code
Ua ntej, cia peb tsim ib daim nplaub tshev tshiab thiab hloov mus rau nws siv lub davhlau ya nyob twg.
Tom qab ntawd peb tsim qhov project Node siv cov lus txib hauv qab no.
Ua ntej, peb nruab qhov yuav tsum tau dependencies.
npm nruabβ
Peb yuav txhawb cov lus txib hauv qab no:
- tshem tawm;
- tsaws;
- nce - lub drone nce ib nrab ib 'meter' thiab hovers;
- down - ntog ib nrab ib 'meter' thiab khov;
- mus rau sab laug - mus ib nrab ib 'meter' mus rau sab laug;
- mus rau sab xis - mus ib nrab ib 'meter' mus rau sab xis;
- kev sib hloov - tig clockwise 90 degrees;
- pem hauv ntej - mus rau pem hauv ntej ib nrab ib 'meter';
- rov qab - rov qab ib nrab ib 'meter';
- nres.
Ntawm no yog cov cai uas tso cai rau koj lees txais cov lus txib, lim lawv thiab tswj lub drone.

Qhov kev pab cuam tuaj yeem raug tso tawm raws li hauv qab no (nws yog ib qho tseem ceeb kom paub tseeb tias lub copter txuas nrog Wi-Fi thiab Ethernet cable txuas nrog lub computer).
Qhib localhost: 3000 hauv qhov browser thiab nyem Start Recognition.
Peb sim tswj lub drone thiab zoo siab.
Tshaj tawm video los ntawm drone
Hauv qhov project, tsim cov ntaub ntawv tshiab thiab luam cov lej no nyob rau hauv:

const drone = require("dronestream");
const server = http.createServer(function(req, res) {
require("fs").createReadStream(__dirname + "/public/video.html").pipe(res);

Cov Tswv Yim Pab Tswvyim
- ya lub drone no nyob hauv tsev.
- Nco ntsoov muab lub npog tiv thaiv ntawm koj lub drone ua ntej tawm mus.
- Xyuas seb lub roj teeb puas raug them.
- Yog hais tias lub drone coj txawv txawv, tuav nws thiab tig nws dua. Qhov kev txiav txim no yuav muab lub copter rau hauv hom xwm txheej ceev thiab cov rotors yuav nres tam sim ntawd.
Npaj code thiab demo
tshwm sim!
Sau code thiab saib lub tshuab pib ua raws yuav ua rau koj txaus siab! Tam sim no peb tau xav txog yuav ua li cas qhia lub drone kom mloog cov lus txib. Qhov tseeb, muaj ntau qhov ua tau zoo: tus neeg siv lub ntsej muag lees paub, kev siv dav dav dav dav, paub piav tes piav taw thiab ntau ntxiv.
