18. Parrot AR Drone 2.0 Wednesday, 15 May 13
19. Specs • WiFi (b/g/n) Router • 1GHz 32Bit ARM Cortex A8 processor • 125 MB DDR2 RAM • Linux 2.6.32 (Busybox) • 720p front facing camera (30fps) • 240p vertical camera (60 fps) • USB 2.0 connector Wednesday, 15 May 13
20. Specs • 3 axis gyroscope (2000º/second precision) • 3 axis accelerometer (± 50mg precision) • 3 axis magentometer (6º precision) • Pressure sensor (±10Pa precision) • Ultrasound sensors • Fully repairable - all components can be ordered • 300 Euro Wednesday, 15 May 13
21. • Connect to it via WiFi • telnet into it • open protocol (Parrot publishes SDK) • commands via UDP packets • https://github.com/felixge/node-ar-drone In a nutshell Wednesday, 15 May 13
22. Some examples // repl.js var arDrone = require('ar-drone'); var client = arDrone.createClient(); client.createRepl(); client.takeoff(); // cli // drone takes off (see script) $ node repl.js drone> clockwise(0.5) // land the drone drone> land() Wednesday, 15 May 13
23. Arduino Wednesday, 15 May 13
24. • open-source electronics prototyping platform • easy-to use • usually programmed with Arduino programming language (based on Wiring) • Made in Italy Overview Wednesday, 15 May 13
25. • none to very little knowledge of electronics necessary • some great beginners kits Wednesday, 15 May 13

27. But where is the JS? Wednesday, 15 May 13
28. Johnny Five Wednesday, 15 May 13
29. Code Example // JOHNNY FIVE var five = require('johnny-five'); var board = new five.Board(); // once the board is ready board.on('ready', function () { // create a new LED object on pin 13 and strobe it (new five.Led(13)).strobe(); }); Wednesday, 15 May 13
30. Compared to // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output. pinMode(13, OUTPUT); } // the loop routine runs over and over again forever: void loop() { // turn the LED on (HIGH is the voltage level) digitalWrite(13, HIGH); // wait for a second delay(1000); // turn the LED off by making the voltage LOW digitalWrite(13, LOW); // wait for a second delay(1000); } Wednesday, 15 May 13

34. Code Wednesday, 15 May 13
35. • physical components are not ‘perfect’ • properties change depending on circumstances • the cheaper the component, the less ‘perfect’ and the more ‘tolerant’ it is • debugging Gotchas Wednesday, 15 May 13
36. Other ideas • create an autonomous drone • create a whole control centre • mash up different modules found on nodecopter.com • build an autonomous greenhouse, etc • your own fantasy is the limit! Wednesday, 15 May 13
37. Conclusion • barrier to entry lower than ever: • lots of information • prices are affordable • use the tools you know Wednesday, 15 May 13
38. “Any application that can be written in JavaScript, will eventually be written in JavaScript.” Atwood’s law Wednesday, 15 May 13
39. Join us • AUG Roma (http://bit.ly/aug-roma) • start of RomaJS meetup • organise a nodecopter event in Rome Wednesday, 15 May 13
