Matou te faʻapipiʻiina le leo o le copter e faʻaaoga ai Node.js ma ARDrone

I lenei aʻoaʻoga o le a tatou vaʻavaʻai i le fatuina o se polokalame mo se drone ma le leo e faʻaaoga ai le Node.js ma le Web speech API. Copter - Parrot ARDrone 2.0.

Matou te faʻamanatu atu ia te oe: mo tagata faitau uma o le "Habr" - o se faʻaitiitiga o 10 rubles pe a lesitala i soʻo se vasega Skillbox e faʻaaoga ai le code promotional "Habr".

Ua fautuaina e Skillbox: Kosi fa'ata'ita'i "Mobile Developer PRO".

Faatomuaga

Drones e ofoofogia. Ou te fiafia tele e taʻalo i laʻu quad, puʻeina ata ma vitio, pe na o le fiafia. Ae o taʻavale ea e leʻi faʻaaogaina (UAV) e faʻaaogaina mo le sili atu nai lo na o faʻafiafiaga. Latou te galulue i fale tifaga, suʻesuʻe glaciers, ma faʻaaogaina e le militeri ma sui o le vaega o faʻatoʻaga.

I lenei aʻoaʻoga o le a matou vaʻavaʻai i le fatuina o se polokalame e mafai ai ona e pulea se drone. fa'aoga leo fa'atonuga. Ioe, o le a faia e le copter le mea e te fai atu ai e fai. I le faaiuga o le tusiga o loʻo i ai se polokalame ua saunia ma le vitio o le pulea o le UAV.

Omea

Matou te manaʻomia mea nei:

• Parrot ARDrone 2.0;
• Uaea Ethernet;
• microphone lelei.

O le atina'e ma le pulega o le a faia i luga o fale faigaluega ma Windows/Mac/Ubuntu. O le tagata lava ia, sa ou galue ma Mac ma Ubuntu 18.04.

Polokalame

La'u mai le lomiga lata mai o Node.js mai nofoaga aloaia.

E manaʻomia foʻi lomiga lata mai o Google Chrome.

Malamalama i le copter

Sei o tatou taumafai e malamalama pe faapefea ona galue Parrot ARDrone. O lenei copter e fa afi.

O loʻo galulue faʻatasi afi i le itu lava e tasi. O le tasi paga e taamilo i le uati, o le isi paga e faafeagai. O le drone e gaoioi e ala i le suia o le maualuga o le faʻaoga e faʻatatau i luga o le fogaeleele, suia le saoasaoa o le taamilosaga o afi ma le tele o isi gaioiga faʻaogaina.

E pei ona mafai ona tatou vaʻaia i le ata o loʻo i luga, o le suia o taʻiala eseese e taʻitaʻia ai se suiga i le itu o le gaioiga o le copter. Mo se faʻataʻitaʻiga, faʻaitiitia pe faʻateleina le saoasaoa o le taamilosaga o le agavale ma le taumatau rotors e fatuina ai se taʻavale. E mafai ai e le drone ona lele i luma pe tua.

E ala i le suia o le saoasaoa ma le itu o afi, matou te seti ai tulimanu faʻasaga e mafai ai e le copter ona gaoioi i isi itu. O le mea moni, mo le poloketi o loʻo i ai nei e le manaʻomia le suʻesuʻeina o le aerodynamics, e tatau ona e malamalama i mataupu faavae.

Auala e galue ai Parrot ARDrone

O le drone o le Wi-Fi hotspot. Ina ia maua ma auina atu poloaiga i le copter, e tatau ona e faʻafesoʻotaʻi i lenei tulaga. E tele talosaga eseese e mafai ai ona e pulea quadcopters. E foliga uma e pei o lenei:

O le taimi lava e fesoʻotaʻi ai le drone, tatala le terminal ma le telnet 192.168.1.1 - o le IP a le copter. Mo Linux e mafai ona e faʻaogaina Linux Busybox.

Faiga fa'aoga

O la matou code o le a vaevaeina i vaega nei:

• fa'aoga fa'aoga ma le tautala API mo le su'eina o leo;
• fa'amamāina o fa'atonuga ma fa'atusatusa i se tulaga;
• auina atu o poloaiga i le drone;
• fa'asalalauga vitiō ola.

E galue le API pe'ā iai se feso'ota'iga Initaneti. Ina ia mautinoa lenei mea, matou te faʻaopoopoina se fesoʻotaʻiga Ethernet.

Ua oo i le taimi e fai ai se talosaga!

Code

Muamua, tatou faia se faila fou ma sui i ai e faʻaaoga ai le faʻamau.

Ona matou faia lea o se poloketi Node e faʻaaoga ai tulafono o loʻo i lalo.

Muamua, matou te faʻapipiʻi mea faʻalagolago e manaʻomia.

npm tāuta 

O le a matou lagolagoina tulafono nei:

• aveese mai;
• tulaueleele;
• i luga - o le drone e alu aʻe i le afa mita ma faʻafefe;
• lalo - pa'ū afa mita ma malolo;
• agavale - alu i le afa mita i le agavale;
• i le itu taumatau - alu i le afa mita i le taumatau;
• taamilosaga - taamilo i le uati 90 tikeri;
• i luma - alu i luma afa mita;
• tua - toe foʻi i tua afa mita;
• taofi.

O le code lea e mafai ai ona e talia poloaiga, faʻamama ma pulea le drone.

• Faalele lenei drone i totonu.
• Tuu i taimi uma le ufiufi puipui i luga o lau drone a'o le'i alu ese.
• Siaki pe ua uma le maa.
• Afai e ese le amio a le drone, taofi i lalo ma fuli i luga. O lenei gaioiga o le a tuʻu ai le copter i le faʻalavelave faʻafuaseʻi ma o le a taofi vave le rotors.
