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 github.com/hybridgroup/gobot && go install github.com/hybridgroup/gobot/platforms/ardrone

How to Use

package main

import (
	"time"

	"github.com/hybridgroup/gobot"
	"github.com/hybridgroup/gobot/platforms/ardrone"
)

func main() {
	gbot := gobot.NewGobot()

	ardroneAdaptor := ardrone.NewArdroneAdaptor("Drone")
	drone := ardrone.NewArdroneDriver(ardroneAdaptor, "Drone")

	work := func() {
		drone.TakeOff()
		gobot.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,
	)
	gbot.AddRobot(robot)

	gbot.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 github.com/hybridgroup/gobot/... && go install github.com/hybridgroup/gobot/platforms/ardrone

Example:

package main

import (
	"time"

	"github.com/hybridgroup/gobot"
	"github.com/hybridgroup/gobot/platforms/ardrone"
)

func main() {
	gbot := gobot.NewGobot()

	ardroneAdaptor := ardrone.NewArdroneAdaptor("Drone")
	drone := ardrone.NewArdroneDriver(ardroneAdaptor, "Drone")

	work := func() {
		drone.TakeOff()
		gobot.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,
	)
	gbot.AddRobot(robot)

	gbot.Start()
}

Types

type ArdroneAdaptor

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

ArdroneAdaptor is gobot.Adaptor representation for the Ardrone

func NewArdroneAdaptor

func NewArdroneAdaptor(name string, v ...string) *ArdroneAdaptor

NewArdroneAdaptor returns a new ArdroneAdaptor and optionally accepts:

string: The ardrones IP Address

func (*ArdroneAdaptor) Connect

func (a *ArdroneAdaptor) Connect() (errs []error)

Connect establishes a connection to the ardrone

func (*ArdroneAdaptor) Finalize

func (a *ArdroneAdaptor) Finalize() (errs []error)

Finalize terminates the connection to the ardrone

func (*ArdroneAdaptor) Name

func (a *ArdroneAdaptor) Name() string

Name returns the ArdroneAdaptors Name

type ArdroneDriver

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

ArdroneDriver is gobot.Driver representation for the Ardrone

func NewArdroneDriver

func NewArdroneDriver(connection *ArdroneAdaptor, name string) *ArdroneDriver

NewArdroneDriver creates an ArdroneDriver with specified name.

It add the following events:

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

func (*ArdroneDriver) Backward

func (a *ArdroneDriver) Backward(speed float64)

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

func (*ArdroneDriver) Clockwise

func (a *ArdroneDriver) Clockwise(speed float64)

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

func (*ArdroneDriver) Connection

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

Connection returns the ArdroneDrivers Connection
