Gobot

GoDoc Build Status Build status Coverage Status Go Report Card License

Gobot (https://gobot.io/) is a framework using the Go programming language (https://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.

Want to run Go directly on microcontrollers? Check out our sister project TinyGo (https://tinygo.org/)

Getting Started

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

Examples

Gobot with Arduino
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
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:

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:

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:

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

You can also specify the api host and port, and turn on authentication:

  master := gobot.NewMaster()
  server := api.NewAPI(master)
  server.Port = "4000"
  server.AddHandler(api.BasicAuth("gort", "klatuu"))
  server.Start()

You may access the robeaux React.js interface with Gobot by navigating to http://localhost:3000/index.html.

CLI

Gobot uses the Gort 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.

Overview

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

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

Classic Gobot

Here is a "Classic Gobot" program that blinks an LED using an Arduino: 

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()
}

Metal Gobot

You can also use Metal Gobot and pick and choose from the various Gobot packages to control hardware with nothing but pure idiomatic Golang code. For example: 

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

Finally, you can use Master Gobot to add the complete Gobot API or control swarms of Robots: 

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()
}

})

someWork.CallCancelFunc() // Cancel next tick and remove from work registry

goroutines for Every and After are run on their own WaitGroups for synchronization: 

someWork2 := myRobot.Every(context.Background(), time.Second * 2, func(){

})

somework2.CallCancelFunc()

// wait for both Every calls to finish

func (*RobotWorkRegistry) Get 

func (rwr *RobotWorkRegistry) Get(id uuid.UUID) *RobotWork
