Isu tinoronga kutonga kwezwi kwecopter tichishandisa Node.js uye ARDrone

Muchidzidzo ichi tichatarisa kugadzira chirongwa che drone ine izwi rekutonga uchishandisa Node.js uye Webhu kutaura API. Copter - Parrot ARDrone 2.0.

Tinoyeuchidza: kune vese vaverengi veHabr - a 10 ruble mutengo paunenge uchinyoresa mune chero Skillbox kosi uchishandisa iyo Habr promo kodhi.

Skillbox inokurudzira: Nzira inoshanda "Mobile Developer PRO".

Nhanganyaya

Drones zvinoshamisa. Ndinofarira kutamba nequad yangu, kutora mafoto nemavhidhiyo, kana kungonakidzwa. Asi motokari dzemuchadenga dzisina kurongwa (UAVs) dzinoshandiswa kune zvinopfuura kungovaraidza. Ivo vanoshanda mumabhaisikopo, kudzidza glaciers, uye vanoshandiswa nemauto nevamiriri vechikamu chekurima.

Muchidzidzo ichi tichatarisa kugadzira chirongwa chinozobvumidza iwe kudzora drone. uchishandisa mirairo yezwi. Hongu, copter ichaita zvaunoiudza kuti iite. Pakupera kwechinyorwa pane yakagadzirira-yakagadzirwa chirongwa uye vhidhiyo yeUAV control.

Iron

Tinoda zvinotevera:

• Parrot ARDrone 2.0;
• Ethernet tambo;
• maikorofoni yakanaka.

Kubudirira uye manejimendi zvichaitwa pamabasa ekushanda neWindows/Mac/Ubuntu. Ini pachangu, ndakashanda neMac uye Ubuntu 18.04.

Software

Dhawunirodha yazvino vhezheni yeNode.js kubva pamutemo nzvimbo.

Zvakare zvinodiwa yazvino vhezheni yeGoogle Chrome.

Kunzwisisa copter

Ngatiedzei kunzwisisa kuti Parrot ARDrone inoshanda sei. Copter iyi ine mota ina.

Anopikisa mota anoshanda munzira imwechete. Peya imwe inotenderera newachi, imwe ichitenderedza wachi. Iyo drone inofamba nekushandura kona yekurerekera kune pamusoro penyika, ichichinja kumhanya kwekutenderera kwemamotor uye mamwe akati wandei anofambiswa mafambiro.

Sezvatinoona mudhayagiramu iri pamusoro, kushandura maparamendi akasiyana-siyana kunotungamira kune shanduko munzira yekufamba kwecopter. Semuenzaniso, kuderedza kana kuwedzera kutenderera kwekutenderera kwekuruboshwe uye kurudyi rotors kunogadzira roll. Izvi zvinobvumira drone kubhururuka mberi kana kumashure.

Nekuchinja kumhanya uye kutungamira kwemamotor, tinoisa makona anotenderedza anobvumira copter kufamba kune mamwe mativi. Chaizvoizvo, kune purojekiti yazvino hapana chikonzero chekudzidza aerodynamics, iwe unongoda kunzwisisa izvo zvakakosha misimboti.

Iyo Parrot ARDrone inoshanda sei

Iyo drone ndeye Wi-Fi hotspot. Kuti ugamuchire uye utumire mirairo kune copter, unofanirwa kubatanidza kune ino. Kune akawanda akasiyana maapplication anotendera iwe kudzora maquadcopter. Zvose zvinotaridzika seizvi:

Kana drone yangobatanidzwa, vhura iyo terminal uye telnet 192.168.1.1 - iyi ndiyo IP yecopter. Kune Linux iwe unogona kushandisa Linux Busybox.

Application architecture

Kodhi yedu ichakamurwa kuita mamodule anotevera:

• mushandisi interface nekutaura API yekuona inzwi;
• kusefa mirairo uye kuenzanisa nechiyero;
• kutumira mirairo kune drone;
• live vhidhiyo kutepfenyura.

Iyo API inoshanda chero paine Internet yekubatanidza. Kuti tive nechokwadi cheizvi, tinowedzera kubatana kweEthernet.

Yasvika nguva yekugadzira application!

Code

Kutanga, ngatigadzire dhairekitori idzva tochinjira kwariri tichishandisa terminal.

Zvadaro tinogadzira chirongwa cheNode tichishandisa mirairo iri pasi apa.

Kutanga, isu tinoisa zvinodiwa zvinoenderana.

npm install 

Tichatsigira mirairo inotevera:

• bvisa;
• kumhara;
• kumusoro - iyo drone inokwira hafu yemamita uye hovers;
• pasi - inowira hafu yemamita uye inotonhora;
• kuruboshwe - inoenda hafu yemamita kuruboshwe;
• kurudyi - inoenda hafu yemamita kurudyi;
• kutenderera - kutenderera wachi 90 madhigirii;
• mberi - inoenda mberi hafu yemamita;
• kumashure - inodzokera shure hafu yemamita;
• stop.

Heino kodhi iyo inokutendera iwe kugamuchira mirairo, kusefa uye kutonga iyo drone.
