WHAT IS OPENROVOpenROV is an open source robotic submarine

designed to make underwater exploration possible foreveryone.

HOW DOES IT LOOK LIKE

HOW DOES IT LOOK LIKE

THE GOALInvented to discover a hidden treasure in an underwater

cave.But also to:

Make underwater exploration accessible to everyoneVery low costExtensible

HIGH LEVEL VIEW

BROWSERPure HTML/JS with Knockout.js

BEAGLEBONENode.js with:ExpressSocket.ioSerialPortmjpg_streamer

ARDUINOControls Motors, Servos, Leds

OPENROV: HOW TOJust plug the ethernet cable, and browse to:

NODE.JS ON THEBEAGLEBONE

If you use the default Angstrom distro, it just works.DEMO

BONESCRIPTArduino-like library to simplify physical computing on the

BeagleBoneGet the lib at https://github.com/jadonk/bonescript

HELLO WORLDrequire('bonescript');

setup = function () { pinMode(bone.USR3, OUTPUT);}

loop = function () { digitalWrite(bone.USR3, HIGH); delay(100); digitalWrite(bone.USR3, LOW); delay(100);}

SHOW ME THE CODEDEMO

CLIENTShows cameraReceives input from users (keyboard or joypad)Displays value from sensors

NODE.JSSpawns a new process for the camera captureCommunicates over socket.io with the browserHandles unpackaging/compilation/upload to the bSends commands to Arduino

ARDUINODrive the motorsTilts the servoLights the LEDsGathers values from sensors

FAKESEliminate dependencies on HW when testing or when

on Azure.

THE FUTUREComplete v1 featuresRefactor codeHandle automatic update of codeAllow extensibility, both HW and SW
