Bebop

The Parrot Bebop and Parrot Bebop 2 are inexpensive quadcopters that can be controlled using their built-in API commands via a WiFi connection. They include 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/...

How to Use

package main

import (
	"time"

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

func main() {
	bebopAdaptor := bebop.NewAdaptor()
	drone := bebop.NewDriver(bebopAdaptor)

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

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

	robot.Start()
}

How to Connect

By default, the Parrot Bebop is a WiFi access point, so there is no additional work to establish a connection to a single drone, you just connect to it.

Once connected, if you want to stream drone video you can either:

- Use the RTP protocol with an external player such as mplayer or VLC.
- Grab the video frames from the drone's data frames, and work with them directly.

Functions

func ValidatePitch

func ValidatePitch(data float64, offset float64) int

ValidatePitch helps validate pitch values such as those created by a joystick to values between 0-100 that are required as params to Parrot Bebop PCMDs

Types

type Adaptor

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

Adaptor is gobot.Adaptor representation for the Bebop

func NewAdaptor

func NewAdaptor() *Adaptor

NewAdaptor returns a new BebopAdaptor

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 Bebop Adaptors Name

func (*Adaptor) SetName

func (a *Adaptor) SetName(n string)

SetName sets the Bebop Adaptors Name

type Driver

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

Driver is gobot.Driver representation for the Bebop

func NewDriver

func NewDriver(connection *Adaptor) *Driver

NewDriver creates an Bebop Driver.

func (*Driver) Backward

func (a *Driver) Backward(speed int)

Backward causes the drone go forward, controls the pitch. speed can be a value from `0` to `100`.

func (*Driver) Clockwise

func (a *Driver) Clockwise(speed int)

Clockwise causes the drone to spin in clockwise direction speed can be a value from `0` to `100`.

func (*Driver) Connection

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

Connection returns the Bebop Drivers Connection

func (*Driver) CounterClockwise

func (a *Driver) CounterClockwise(speed int)

CounterClockwise the drone to spin in counter clockwise direction speed can be a value from `0` to `100`.

func (*Driver) Down

func (a *Driver) Down(speed int)

Down makes the drone reduce altitude. speed can be a value from `0` to `100`.

func (*Driver) Forward

func (a *Driver) Forward(speed int)

Forward causes the drone go forward, controls the pitch. speed can be a value from `0` to `100`.

func (*Driver) Halt

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

Halt halts the Bebop Driver
