DroneJS

A Node.js based library for controlling a Parrot minidrone. The library also provides the feature to take pictures from the drone, download them all at a time and delete them whenever required. The library follows Bluetooth LE networking protocol to connect to the drone.

Drones Supported

• Parrot Rolling Spider
• Parrot Airborne Night Maclane
• Parrot Airborne Night Blaze
• Parrot Airborne Night Swat
• Parrot Airborne Cargo Mars
• Parrot Airborne Cargo Travis

Prerequisites

• See noble prerequisites for your platform
• Node.js 6.5 or higher

Install

npm install dronejs

Usage

Connect

To connect to drone, you need to instantiate the MiniDrone class and then call its connect method.

var minidrone = require('dronejs');

minidrone.connect('RS_')
        .then()
        .catch((e) => {
            console.log('Error occurred: ' + e);
        });

Setup Navdata Stream

To listen to the navigation data from the drone, you need to call the getNavDataStream function and then subscribe to the object returned from it.

var minidrone = require('dronejs');

var navDataStream = minidrone.getNavDataStream();
navDataStream.subscribe((data) => {
        console.log(data);
    },
    err => debug(err),
    () => debug('complete'));


minidrone.connect('RS_')
    .then(() => minidrone.checkAllStates())
    .then()
    .catch((e) => {
        console.log('Error occurred: ' + e);
    });

Basic Maneuvers

var minidrone = require('dronejs');

var navDataStream = minidrone.getNavDataStream();
navDataStream.subscribe((data) => {
        console.log(data);
    },
    err => debug(err),
    () => debug('complete'));


minidrone.connect('RS_')
    .then(() => minidrone.flatTrim())
    .then(() => minidrone.takeOff())
    .then(() => minidrone.flatTrim())
    .then(() => minidrone.forward(50, 5))
    .then(() => minidrone.flatTrim())
    .then(() => minidrone.land())
    .then()
    .catch((e) => {
        console.log('Error occurred: ' + e);
    });

Take Picture

var minidrone = require('dronejs');

var navDataStream = minidrone.getNavDataStream();
navDataStream.subscribe((data) => {
        console.log(data);
    },
    err => debug(err),
    () => debug('complete'));


minidrone.connect('RS_')
    .then(() => minidrone.flatTrim())
    .then(() => minidrone.takeOff())
    .then(() => minidrone.flatTrim())
    .then(() => minidrone.takePicture())
    .then(() => minidrone.flatTrim())
    .then(() => minidrone.land())
    .then()
    .catch((e) => {
        console.log('Error occurred: ' + e);
    });

Download Pictures

var minidrone = require('dronejs');

minidrone.connect('RS_')
    .then(() => minidrone.listAllPictures())
    .then(pictures => minidrone.downloadPicture(pictures[0], 'output'))
    .then(response => {
        if (response === 'success') {
            console.log('picture downloaded successfully...');
        }
    })
    .catch((e) => {
        console.log('Error occurred: ' + e);
    });

Delete Picture

var minidrone = require('dronejs');

minidrone.connect('RS_')
    .then(() => minidrone.listAllPictures())
    .then(pictures => minidrone.deletePicture(pictures[0]))
    .then(response => {
        if (response === 'success') {
            console.log('picture deleted successfully...');
        }
    })
    .catch((e) => {
        console.log('Error occurred: ' + e);
    });
