Utg\u00e5van av projektet OpenBot 0.5 har publicerats, en plattform f\u00f6r att skapa r\u00f6rliga hjulrobotar vars grund \u00e4r en vanlig Android-smartphone. Plattformen har utvecklats i forskningsavdelningen hos Intel och vidareutvecklar id\u00e9n om att utnyttja smartphone:ns ber\u00e4kningsm\u00f6jligheter och de inbyggda funktionerna s\u00e5som GPS, gyroskop, kompass och kamera vid skapandet av robotar. <\/p>\n

Programvaran f\u00f6r att styra roboten, analysera omgivningen och autonom navigation har implementerats som en app f\u00f6r Android-plattformen. Koden \u00e4r skriven i Java, Kotlin och C++ och distribueras under MIT-licensen. Plattformen f\u00f6rv\u00e4ntas vara anv\u00e4ndbar f\u00f6r att l\u00e4ra sig om robotteknik, snabbt skapa egna prototyper av r\u00f6rliga robotar och bedriva forskning relaterad till autopiloter och autonom navigation. <\/p>\n

OpenBot g\u00f6r det m\u00f6jligt att p\u00e5 ett kostnadseffektivt s\u00e4tt b\u00f6rja experimentera med r\u00f6rliga robotar - f\u00f6r att skapa en robot kan man klara sig med en smartphone i medelprisklassen och ytterligare komponenter som kostar totalt cirka 50 dollar. Chassit f\u00f6r roboten samt tillbeh\u00f6r f\u00f6r att f\u00e4sta smartphonen kan skrivas ut p\u00e5 en 3D-skrivare efter f\u00f6reslagna m\u00f6nster (om man inte har tillg\u00e5ng till en 3D-skrivare kan man sk\u00e4ra ut ramen i kartong eller plywood). R\u00f6relsen drivs av fyra elektriska motorer.

F\u00f6r att styra motorerna, tillbeh\u00f6ren och extra sensorer, samt f\u00f6r att \u00f6vervaka batteriladdningen, anv\u00e4nds ett Arduino Nano-kort baserat p\u00e5 mikrokontrollern ATmega328P, som ansluts till smartphone:n via USB-porten. Dessutom st\u00f6djer den anslutning av hastighetssensorer och ultraljudssensorer. Fj\u00e4rrstyrningen av roboten kan ske via en Android-klientapp, via en dator som \u00e4r ansluten till samma WiFi-n\u00e4tverk, genom webbl\u00e4saren eller genom en spelkontroll med Bluetooth-st\u00f6d (t.ex. PS4, XBox och X3).

Den k\u00f6rbara programvaran p\u00e5 smarttelefonen inneh\u00e5ller ett maskininl\u00e4rningssystem f\u00f6r objektigenk\u00e4nning (identifierar omkring 80 typer av objekt) och utf\u00f6r autopilotfunktioner. Applikationen g\u00f6r det m\u00f6jligt f\u00f6r roboten att identifiera specifika f\u00f6rem\u00e5l, kringg\u00e5 hinder, f\u00f6lja ett valt objekt samt l\u00f6sa autonom navigering. Till exempel kan roboten i autopilotl\u00e4ge flytta till en specificerad plats och anpassa sig efter f\u00f6r\u00e4ndringar i omgivningen. R\u00f6relsen kan \u00e4ven styras manuellt, d\u00e4r roboten anv\u00e4nds som en fj\u00e4rrstyrd r\u00f6rlig kamera.

I den nya versionen har firmware f\u00f6r Arduino genomg\u00e5tt betydande omarbetning, d\u00e4r st\u00f6d f\u00f6r ytterligare typer av robotar (RTR och RC) har lagts till. Android-applikationen har f\u00e5tt st\u00f6d f\u00f6r det nya meddelandeutbytesprotokollet med mikrokontrollerfirmwaren, vilket m\u00f6jligg\u00f6r bearbetning av konfigurationmeddelanden och omarbetad kontrollst\u00f6d med hj\u00e4lp av spelkontroller. Nya modeller f\u00f6r 3D-utskrift av det nya chassit RC-Truck har lagts till.

En knapp f\u00f6r att v\u00e4xla kameran p\u00e5 roboten har lagts till i klientapplikationen, och st\u00f6det f\u00f6r RTSP-protokollet har upph\u00f6rt till f\u00f6rm\u00e5n f\u00f6r WebRTC. I webgr\u00e4nssnittet baserat p\u00e5 Node.js erbjuds m\u00f6jligheten till fj\u00e4rrstyrning av robotens r\u00f6relser via webbl\u00e4saren, med \u00f6verf\u00f6ring av data fr\u00e5n robotens videokamera via WebRTC.
