Ardrone

The ARDrone from Parrot is an inexpensive quadcopter that is controlled using WiFi. It includes a built-in front-facing HD video camera, as well as a second lower resolution bottom facing video camera.

How to Install

go get -d -u gobot.io/x/gobot/... && go install gobot.io/x/gobot/platforms/parrot/ardrone

How to Use

package main

import (
	"time"

	"gobot.io/x/gobot"
	"gobot.io/x/gobot/platforms/parrot/ardrone"
)

func main() {
	ardroneAdaptor := ardrone.NewAdaptor("Drone")
	drone := ardrone.NewDriver(ardroneAdaptor, "Drone")

	work := func() {
		drone.On(drone.Event("flying"), func(data interface{}) {
			gobot.After(3*time.Second, func() {
				drone.Land()
			})
		})
		drone.TakeOff()
	}

	robot := gobot.NewRobot("drone",
		[]gobot.Connection{ardroneAdaptor},
		[]gobot.Device{drone},
		work,
	)

	robot.Start()
}

How to Connect

The ARDrone is a WiFi device, so there is no additional work to establish a connection to a single drone. However, in order to connect to multiple drones, you need to perform some configuration steps on each drone via SSH.

Overview

Package ardrone provides the Gobot adaptor and driver for the Parrot Ardrone.

Installing:

go get -d -u gobot.io/x/gobot/... && go install gobot.io/x/gobot/platforms/parrot/ardrone

Example:

package main

import (
	"time"

	"gobot.io/x/gobot"
	"gobot.io/x/gobot/platforms/parrot/ardrone"
)

func main() {
	ardroneAdaptor := ardrone.NewAdaptor()
	drone := ardrone.NewDriver(ardroneAdaptor)

	work := func() {
		drone.TakeOff()
		drone.On(drone.Event("flying"), func(data interface{}) {
			gobot.After(3*time.Second, func() {
				drone.Land()
			})
		})
	}

	robot := gobot.NewRobot("drone",
		[]gobot.Connection{ardroneAdaptor},
		[]gobot.Device{drone},
		work,
	)

	robot.Start()
}

Constants

const (
	// Flying event
	Flying = "flying"
)

Types

type Adaptor

type Adaptor struct {
	// contains filtered or unexported fields
}

Adaptor is gobot.Adaptor representation for the Ardrone

func NewAdaptor

func NewAdaptor(v ...string) *Adaptor

NewAdaptor returns a new ardrone.Adaptor and optionally accepts:

string: The ardrones IP Address

func (*Adaptor) Connect

func (a *Adaptor) Connect() (err error)

Connect establishes a connection to the ardrone

func (*Adaptor) Finalize

func (a *Adaptor) Finalize() (err error)

Finalize terminates the connection to the ardrone

func (*Adaptor) Name

func (a *Adaptor) Name() string

Name returns the Adaptor Name

func (*Adaptor) SetName

func (a *Adaptor) SetName(n string)

SetName sets the Adaptor Name

type Driver

type Driver struct {
	gobot.Eventer
	// contains filtered or unexported fields
}

Driver is gobot.Driver representation for the Ardrone

func NewDriver

func NewDriver(connection *Adaptor) *Driver

NewDriver creates an Driver for the ARDrone.

It add the following events:

'flying' - Sent when the device has taken off.

func (*Driver) Backward

func (a *Driver) Backward(speed float64)

Backward causes the drone go backward, controls the pitch. speed can be a value from `0.0` to `1.0`.

func (*Driver) Clockwise

func (a *Driver) Clockwise(speed float64)

Clockwise causes the drone to spin in clockwise direction speed can be a value from `0.0` to `1.0`.

func (*Driver) Connection

func (a *Driver) Connection() gobot.Connection

Connection returns the Driver Connection

func (*Driver) CounterClockwise

func (a *Driver) CounterClockwise(speed float64)

CounterClockwise the drone to spin in counter clockwise direction speed can be a value from `0.0` to `1.0`.

func (*Driver) Down

func (a *Driver) Down(speed float64)

Down makes the drone reduce altitude. speed can be a value from `0.0` to `1.0`.

func (*Driver) Forward

func (a *Driver) Forward(speed float64)

Forward causes the drone go forward, controls the pitch. speed can be a value from `0.0` to `1.0`.

func (*Driver) Halt

func (a *Driver) Halt() (err error)

Halt halts the Driver

func (*Driver) Hover

func (a *Driver) Hover()

Hover makes the drone to hover in place.
