introduction
Fuci mirabiles. Vere fruor ludere cum quad mea, imagines et videos accipiens, vel tantum ludis. Sed vehicula aerea inanibus (UAVs) pluribus quam iustis oblectamentis adhibentur. In cinematographico, studio molibus laborant, et a militaribus et repraesentativis regiones agriculturae utuntur.
In hoc doceo videbimus rationem creandi quae te fucum regere sinet. voce utens imperat. Imo faciet copter quod tu narras. In fine articuli programmata prompta facta est et video imperii UAV.
ferrum
Sequenti opus est:
- Psittacus ARDrone 2.0;
- Aer cable;
- bonum tortor ligula.
Progressio et procuratio in operibus Windows/Mac/Ubuntu exercebuntur. Personaliter cum Mac et Ubuntu 18.04 laboravi.
software
Download novissimam versionem Node.js from .
Etiam opus .
Intellectus copter
Conemur intelligere quomodo opera Parrot ARDrone. Hic coptra quattuor motores habet.
Eadem directione operantur contraria motorum. Unum par horologico, alterum counterclockwise gyrat. Fucus movetur mutando angulum inclinationis respectu superficiei terrae, mutando celeritatem rotationis motorum et plurium aliorum motuum discurrendorum.
Ut videre est in schemate supra, varias varias parametros mutando ducit ad directionem motus aeris. Exempli gratia rotationis sinistrae et dextrae velocitatem decrescentes vel augentes rotors volumen creat. Hoc fucum vel retro vel retro avolare permittit.
Mutando velocitatem et directionem motorum constituimus angulos beniculos, qui coptra in alias partes movere permittunt. Profecto in praesenti incepto opus non est studere aerodynamica, vos iustus postulo ut elementa elementa intellegamus.
Ut Parrot ARDrone operatur
Fucus Wi-FI hotspot est. Ad mandatum coptri accipiendum et mittendum, hoc loco coniungere debes. Multae variae applicationes sunt quae te quadcopters regere permittunt. Res omnes sic spectat:
Cum fucus coniungitur, terminalem et telnet aperi 192.168.1.1 - hoc IP coptri est. Pro Linux uti potes .
Applicationem architectura
Codex noster in modulos sequentes dividetur:
- usor interface cum loquela API pro voce detectio;
- eliquare imperia et cum vexillo comparare;
- mandata ad fucum mittens;
- Vivamus eget molestie lacus.
API laborat modo dum nexus interreti est. Hoc ut fiat, nexum Aer addimus.
Tempus est applicationem creare!
Code
Primum, novam folder faciamus et ad eam terminatio utens commutandum.
Tunc Node inceptis mandatis infra utentes creamus.
Primum, debitas clientelas instituimus.
install npm
Mandata sequentia adiuvabimus;
- takeoff;
- appulsum;
- fucus surgit dimidii metri et uncis;
- deorsum — dimidius metri cadit et coit;
- ad lævam - vadit dimidium metri ad sinistram;
- ad dextram - vadit dimidium metri ad dextram;
- gyratio - in horologio horologico 90 gradus;
- procedat - goes forward dimidium metri;
- retro - redit dimidium metri;
- prohibere.
Hic est signum quod tibi permittit ut mandata accipias, ea colas et fucum domas.

benevolens innuit
- Fuge hac fucum intus.
- Semper operculum tutelae in fuco tuo pone priusquam auferas.
- Reprehendo si altilium oneratur.
- Si fucus mirum in modum se gerit, eam deprimit et superinducite. Haec actio coptram in modum subitis ponet et rotors statim cessabunt.
Promptus codice ac demo
Accidit!
Codicis scripturae ac deinde machinae vigilantes incipiunt: parere tibi placuere dabo! Nunc figuratum est quomodo docere fucum audire iubeat. Re vera, sunt multo plura possibilitates: usus vultus agnitio, volatus sui iuris, gestus cognitio et multo magis.
