Meh.
“It’s all talk until the code runs.” —Ward Cunningham
Prerequisites Node.js nodejs.org NPM npmjs.org
$ npm install ar-drone
Connect to the drone
var arDrone = require( 'ar-‐drone' ); var client = arDrone.createClient();
client.takeoff(); client.after( 4000, function() { this.stop(); this.land(); }); Save this in takeoff-and-land.js
$ node takeoff-and-land.js
// argument: speed 0-‐1 client.up( 1 ); // altitude client.down(
1 ); client.left( 1 ); // bank (roll) client.right( 1 ); // bank (roll) client.front( 1 ); // pitch client.back( 1 ); // pitch client.clockwise( 1 ); // yaw (spin) client.counterClockwise( 1 ); // yaw (spin) client.stop(); // movement=0 Also http://ministryoftype.co.uk/words/article/pitch_bank_and_yaw/
client.animate('flipLeft', 1500); client.animate('flipRight', 1500); /* 'phiM30Deg', 'phi30Deg', 'thetaM30Deg', 'theta30Deg', 'theta20degYaw200deg',
'theta20degYawM200deg', 'turnaround', 'turnaroundGodown', 'yawShake', 'yawDance', 'phiDance', 'thetaDance', 'vzDance', 'wave', 'phiThetaMixed', 'doublePhiThetaMixed', 'flipAhead', 'flipBehind' */ Also
var pngStream = client.getPngStream(); pngStream.on('data', console.log); var videoStream = client.getVideoStream();
videoStream.on('data', console.log); Camera
var arDrone = require( 'ar-‐drone' ); var fs = require(
'fs' ); var client = arDrone.createClient(); var png = client.getPngStream(); png.on( 'error', function ( error ) { console.error( 'error: ' + err ); }); png.on( 'data', function( buffer ) { console.log( buffer.length ); fs.writeFile( 'camera.png', buffer, 'binary', function( error ) { if( error ) { console.log( error ); } else { console.log( 'Success.' ); } process.exit(0); }); }); Take a picture, save it to the file system
Full API https://github.com/felixge/node-ar-drone
Bonus Round http://opencv.org/ https://github.com/peterbraden/node- opencv
var cv = require('opencv'); cv.readImage("./hobbiton.jpg", function(err, im){ im.detectObject(cv.FACE_CASCADE, {},
function(err, faces){ for (var i=0;i<faces.length; i++){ var x = faces[i]; im.ellipse(x.x + x.width/2, x.y + x.height/2, x.width/2, x.height/2); } im.save('./hobbiton-‐faces.jpg'); }); }); Find the faces in a picture
