[![Gobot](https://raw.githubusercontent.com/hybridgroup/gobot-site/master/source/images/elements/gobot-logo-small.png)](http://gobot.io/)

Gobot (http://gobot.io/) is a framework using the Go programming language (http://golang.org/) for robotics, physical computing, and the Internet of Things.

It provides a simple, yet powerful way to create solutions that incorporate multiple, different hardware devices at the same time.

## Getting Started

Get the Gobot source with: `go get -d -u gobot.io/x/gobot/...`

## Examples

#### Gobot with Arduino

```go
package main

import (
	"time"

	"gobot.io/x/gobot"
	"gobot.io/x/gobot/drivers/gpio"
	"gobot.io/x/gobot/platforms/firmata"
)

func main() {
	firmataAdaptor := firmata.NewAdaptor("/dev/ttyACM0")
	led := gpio.NewLedDriver(firmataAdaptor, "13")

	work := func() {
		gobot.Every(1*time.Second, func() {
			led.Toggle()
		})
	}

	robot := gobot.NewRobot("bot",
		[]gobot.Connection{firmataAdaptor},
		[]gobot.Device{led},
		work,
	)

	robot.Start()
}
```

#### Gobot with Sphero

```go
package main

import (
	"fmt"
	"time"

	"gobot.io/x/gobot"
	"gobot.io/x/gobot/platforms/sphero"
)

func main() {
	adaptor := sphero.NewAdaptor("/dev/rfcomm0")
	driver := sphero.NewSpheroDriver(adaptor)

	work := func() {
		gobot.Every(3*time.Second, func() {
			driver.Roll(30, uint16(gobot.Rand(360)))
		})
	}

	robot := gobot.NewRobot("sphero",
		[]gobot.Connection{adaptor},
		[]gobot.Device{driver},
		work,
	)

	robot.Start()
}
```

#### "Metal" Gobot

You can use the entire Gobot framework as shown in the examples above ("Classic" Gobot), or you can pick and choose from the various Gobot packages to control hardware with nothing but pure idiomatic Golang code ("Metal" Gobot). For example:

```go
package main

import (
	"gobot.io/x/gobot/drivers/gpio"
	"gobot.io/x/gobot/platforms/intel-iot/edison"
	"time"
)

func main() {
	e := edison.NewAdaptor()
	e.Connect()

	led := gpio.NewLedDriver(e, "13")
	led.Start()

	for {
		led.Toggle()
		time.Sleep(1000 * time.Millisecond)
	}
}
```

#### "Master" Gobot

You can also use the full capabilities of the framework aka "Master Gobot" to control swarms of robots or other features such as the built-in API server. For example:

```go
package main

import (
	"fmt"
	"time"

	"gobot.io/x/gobot"
	"gobot.io/x/gobot/api"
	"gobot.io/x/gobot/platforms/sphero"
)

func NewSwarmBot(port string) *gobot.Robot {
	spheroAdaptor := sphero.NewAdaptor(port)
	spheroDriver := sphero.NewSpheroDriver(spheroAdaptor)
	spheroDriver.SetName("Sphero" + port)

	work := func() {
		spheroDriver.Stop()

		spheroDriver.On(sphero.Collision, func(data interface{}) {
			fmt.Println("Collision Detected!")
		})

		gobot.Every(1*time.Second, func() {
			spheroDriver.Roll(100, uint16(gobot.Rand(360)))
		})
		gobot.Every(3*time.Second, func() {
			spheroDriver.SetRGB(uint8(gobot.Rand(255)),
				uint8(gobot.Rand(255)),
				uint8(gobot.Rand(255)),
			)
		})
	}

	robot := gobot.NewRobot("sphero",
		[]gobot.Connection{spheroAdaptor},
		[]gobot.Device{spheroDriver},
		work,
	)

	return robot
}

func main() {
	master := gobot.NewMaster()
	api.NewAPI(master).Start()

	spheros := []string{
		"/dev/rfcomm0",
		"/dev/rfcomm1",
		"/dev/rfcomm2",
		"/dev/rfcomm3",
	}

	for _, port := range spheros {
		master.AddRobot(NewSwarmBot(port))
	}

	master.Start()
}
```

## API:

Gobot includes a RESTful API to query the status of any robot running within a group, including the connection and device status, and execute device commands.

To activate the API, import the `gobot.io/x/gobot/api` package and instantiate the `API` like this:

```go
  master := gobot.NewMaster()
  api.NewAPI(master).Start()
```

You can also specify the api host and port, and turn on authentication:
```go
  master := gobot.NewMaster()
  server := api.NewAPI(master)
  server.Port = "4000"
  server.AddHandler(api.BasicAuth("gort", "klatuu"))
  server.Start()
```

You may access the [robeaux](https://github.com/hybridgroup/robeaux) React.js interface with Gobot by navigating to `http://localhost:3000/index.html`.

## CLI

Gobot uses the Gort [http://gort.io](http://gort.io) Command Line Interface (CLI) so you can access important features right from the command line. We call it "RobotOps", aka "DevOps For Robotics". You can scan, connect, update device firmware, and more!

Gobot also has its own CLI to generate new platforms, adaptors, and drivers. You can check it out in the `/cli` directory.
