Many developers know or have heard of it and it’s a great platform for experiments. Download NodeJS, if it’s not installed. When NodeJS is installed, we need to install the ar-drone NodeJS plugin: Open a NodeJS console and change to your home folder e.g. “C:\Users\”, on Windows 10. Run: npm install ar-drone Later on, you can try the more mission oriented control API ardrone-atonomy  NODEJS AND JAVASCRIPT API BEFORE RUNNING ANY DRONE CODE Make sure you have enough space for playing with the drone Create a NodeJS project, in your favorite IDE or a JavaScript file that runs in the context of NodeJS Prepare to leave the Internet, when you connect to the drone WiFi Connect the computer to the drone Wi-Fi Try to telnet (port:23) or ftp (port:5551) on the default host IP 192.168.1.1 (anonymously) RUNNING THE AR-DRONE EXAMPLES Open a NodeJS console, in the folder: \node_modules\ar-drone\examples Run node simpleFlight.js MAKE SURE THE DRONE HAS ENOUGH SPACE TO TAKEOFF !!  A “HELLO WORLD” SNIPPET var drone = require("ar-drone"); var client = drone.createClient(); client.takeoff(); client.after(5000, function() { this.clockwise(0.5); }).after(3000, function() { this.stop(); this.land(); }); PROGRAMMING THE DRONE IS EASY! Made this web based drone console, with NodeJS, JQuery, Angular, Web Sockets, WebGL..., in less than a week and I was totally in flow, just like when I played with Lego as a child.  THE MISSION PANEL Making it possible to define a mission queue and send a timed and specific navigation-, configuration- and LED mission to the drone, including waiting between commands. THE NAVIGATION PANEL The drone has a set of cool animation gestures, which can be used via the API and the Freeflight mobile app.  THE CONFIGURATION PANEL YOU CAN CONFIGURE LOTS OF SETTINGS FOR THE DRONE. general:navdata_demo control:control_level gps:latitude general:navdata_options control:euler_angle_max gps:latitude general:ardrone_name control:control_iphone_tilt gps:altitude general:com_watchdog control:control_vz_max control:control_yaw network:ssid_single_player leds:leds_anim control:outdoor network:ssid_multi_player control:flight_without_shell network:wifi_rate video:video_channel control:indoor_euler_angle_max network:owner_mac video:codec_fps control:indoor_control_vz_max network:wifi_mode video:video_codec control:indoor_control_yaw video:video_slices control:outdoor_euler_angle_max detect:detections_select_h video:video_live_socket control:outdoor_control_vz_max detect:detections_select_v video:bitrate control:outdoor_control_yaw detect:detections_select_v_hsync video:max_bitrate control:flying_mode detect:detect_type video:bitrate_control_mode control:flight_anim detect:enemy_colors video:bitrate_storage control:hovering_range detect:groundstripe_colors video:video_on_usb control:altitude_min detect:enemy_without_shell video:video_file_index control:altitude_max THERE ARE MORE SETTINGS, ON THE DRONE FILE SYSTEM. Via telnet you can access files like, cat /data/config.ini cat /proc/cpuinfo cat /proc/meminfo And a lot of other files and settings.  NAVDATA The drone sends a variety of categorized and subscription-enabled data entities Here are some of the them – droneState, demo , rawMeasures, physMeasures, gyroOffsets, eularAngles, references, trims, pwm, altitude, visionRaw, vision, visionPerf, trackersSend, visionDetect, adcDataFrame, videoStream, games, pressureRaw, magneto, windSpeed, kalmanPressure, hdvideoStream, wifi, gps...  USING THE DRONE NAVDATA // JS BACKEND: SUBSCRIBING TO NAVDATA FROM THE DRONE, ON THE SERVER SIDE. var drone = require("ar-drone"); var constants = require("ar-drone/lib/constants"); var client = drone.createClient(); var options = ( 1
