php-ar-drone

php-ar-drone is a port of node-ar-drone which allows user to control a Parrot AR Drone over PHP. No, isn't a joke.

This library provide the same features that the node library, that's why this documentation is heavy based on the node-ar-drone one. The low level UdpControl API is not implemented yet.

This library is built on the awesome reactphp library which bring non blocking i/o system to PHP.

Installation

Using Composer:

composer require jolicode/php-ar-drone dev-master

Usage

Some examples are located in the examples/ directory. Feel free to test those.

Client API

$client = new \Joli\ArDrone\Client();
// use API service (see below)
$client->start();

$client->takeoff($callback)

Sets the internal fly state to true, $callback is invoked after the drone reports that it is hovering.

$client->land($callback)

Sets the internal fly state to false, $callback is invoked after the drone reports it has landed.

$client->up($speed) / $client->down($speed)

Makes the drone gain or reduce altitude. $speed can be a value from 0 to 1.

$client->clockwise($speed) / $client->counterClockwise($speed)

Causes the drone to spin. $speed can be a value from 0 to 1.

$client->front($speed) / $client->back($speed)

Controls the pitch, which a horizontal movement using the camera as a reference point. $speed can be a value from 0 to 1.

$client->left($speed) / $client->right($speed)

Controls the roll, which is a horizontal movement using the camera as a reference point. $speed can be a value from 0 to 1.

$client->stop()

Sets all drone movement commands to 0, making it effectively hover in place.

Events

A client will emit landed, hovering, flying, landing, batteryChange, and altitudeChange events as long as demo navdata is enabled. Here is a example for catching event:

$client->on('landed', function() {
    // do something
});
