An implementation of the networking protocols used by the Parrot AR Drone 2.0. It appears that 1.0 drones are also compatible. Install via Github to get the latest version: Or, if you're fine with missing some cutting edge stuff, go for npm: The AR Drone is an affordable, yet surprisingly capable quadcopter. itself runs a proprietary firmware that can be controlled via WiFi using the official (available for iOS and Android). Unlike the firmware, the client protocol is open, and Parrot publishes an SDK (signup required to download) including a good amount of documentation and CTheir target audience seems to be mobile developers who can use this SDK to create games and other apps for people to have more fun with their drones. However, the protocol can also be used to receive video and sensor data, enabling developers to write autonomous programs for the upcoming robot revolution. This module is still under heavy development, so please don't be suprised if

you find some functionality missing or undocumented. However, the documented parts are tested and should work well for most parts. This module exposes a high level Client API that tries to support all drone features, while making them easy to use. The best way to get started is to create a repl.js file like this: Using this REPL, you should be able to have some fun:ar drone battery duration Now you could write an autonomous program that does the same:macdev drone dx or empire axe Ok, but what if you want to make your drone to interact with something? parrot ar drone belgique you could start by looking at the sensor data:black ops 2 drone out of map

Not all of this is handled by the Client library yet, but you should at the very least be able to receive droneState and demo data. A good initial challenge might be to try flying to a certain altitude based on the navdata.demo.altitudeMeters property. Once you have manged this, you may want to try looking at the camera image. is a simple way to get this as PngBuffers (requires a recent ffmpeg version torc uav drone for sale be found in your $PATH):drone with camera review Your first challenge might be to expose these png images as a node http webOnce you have done that, you should try feeding them into the Returns a new Client object. Launches an interactive interface with all client methods available in theAdditionally client resolves to the client instance itself. Returns a PngEncoder object that emits individual png image buffers as 'data'

Multiple calls to this method returns the same object. (e.g. reconnect on error) is managed by the client. Returns a TcpVideoStream object that emits raw tcp packets as 'data' Sets the internal fly state to true, callback is invoked after the drone reports that it is hovering. Sets the internal fly state to false, callback is invoked after the drone reports it has landed. Makes the drone gain or reduce altitude. speed can be a value from 0 to 1. Causes the drone to spin. Controls the pitch, which a horizontal movement using the camera as a reference point. Controls the roll, which is a horizontal movement using the camera Sets all drone movement commands to 0, making it effectively hover in place. Asks the drone to calibrate a device. supports only one device that can be calibrated: the magnetometer, which is device number 0. The magnetometer can only be calibrated while the drone is flying, and the calibration routine causes the drone to yaw in place a full 360

Sends a config command to the drone. You will need to download the drone SDK to find a full list of commands in the ARDrone_Developer_Guide.pdf. For example, this command can be used to instruct the drone to send all navdata. callback is invoked after the drone acknowledges the config request or if a timeout occurs. Alternatively, you can pass an options object containing the following: Performs a pre-programmed flight sequence for a given duration (in ms). animation can be one of the following: Please note that the drone will need a good amount of altitude and headroom to perform a flip. Performs a pre-programmed led sequence at given hz frequency and durationanimation can be one of the following: Causes the emergency REF bit to be set to 1 untilThis recovers a drone that has flipped over and is showing red lights to be flyable again and show greenIt is also done implicitly when creating a new high level client. A client will emit landed, hovering, flying, landing, batteryChange, and altitudeChange events as long as demo navdata is enabled.

To enable demo navdata use This is a low level API. If you prefer something simpler, check out the Client The drone is controlled by sending UDP packets on port 5556. does not guarantee message ordering or delivery, clients must repeatedly send their instructions and include an incrementing sequence number with each For example, the command used for takeoff/landing (REF), with a sequence number of 1, and a parameter of 512 (takeoff) looks like this: To ease the creation and sending of these packets, this module exposes an UdpControl class handling this task. For example, the following program will cause your drone to takeoff and hover in place. Now that you are airborne, you can fly around by passing an argument to theA full list of all pcmd() options can be found in the API docs With what you have learned so far, you could create a simple program Creates a new UdpControl instance where options can include: Enqueues a raw AT* command.
