README.md

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 github.com/hybridgroup/gobot/...

Examples

Gobot with Arduino

package main

import (
	"time"

	"github.com/hybridgroup/gobot"
	"github.com/hybridgroup/gobot/platforms/firmata"
	"github.com/hybridgroup/gobot/platforms/gpio"
)

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

	firmataAdaptor := firmata.NewFirmataAdaptor("arduino", "/dev/ttyACM0")
	led := gpio.NewLedDriver(firmataAdaptor, "led", "13")

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

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

	gbot.AddRobot(robot)

	gbot.Start()
}

Gobot with Sphero

package main

import (
	"fmt"
	"time"

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

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

	adaptor := sphero.NewSpheroAdaptor("sphero", "/dev/rfcomm0")
	driver := sphero.NewSpheroDriver(adaptor, "sphero")

	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,
	)

	gbot.AddRobot(robot)

	gbot.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 (
	"github.com/hybridgroup/gobot/platforms/gpio"
	"github.com/hybridgroup/gobot/platforms/intel-iot/edison"
	"time"
)

func main() {
	e := edison.NewEdisonAdaptor("edison")
	e.Connect()

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

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

Hardware Support

Gobot has a extensible system for connecting to hardware devices. The following robotics and physical computing platforms are currently supported:

• AR Drone 2.0 <=> Package
• Arduino <=> Package
• Audio <=> Package
• Beaglebone Black <=> Package
• Bebop <=> Package
• Bluetooth LE <=> Package
• C.H.I.P <=> Package
• Digispark <=> Package
• Intel Edison <=> Package
• Joystick <=> Package
• Keyboard <=> Package
• Leap Motion <=> Package
• MavLink <=> Package
• MQTT <=> Package
• Neurosky <=> Package
• NATS <=> Package
• OpenCV <=> Package
• Pebble <=> Package
• Raspberry Pi <=> Package
• Spark <=> Package
• Sphero <=> Package

Support for many devices that use General Purpose Input/Output (GPIO) have a shared set of drivers provided using the gobot/platforms/gpio package:

• GPIO <=> Drivers
  • Analog Sensor
  • Button
  • Buzzer
  • Direct Pin
  • Grove Button
  • Grove Buzzer
  • Grove LED

  • Grove Rotary Dial
  • Grove Sound Sensor
  • Grove Temperature Sensor
  • Grove Touch Sensor
  • LED
  • Makey Button
  • Motor
  • Relay
  • RGB LED
  • Servo

Support for devices that use Inter-Integrated Circuit (I2C) have a shared set of drivers provided using the gobot/platforms/i2c package:

• I2C <=> Drivers
  • BlinkM
  • Grove Digital Accelerometer
  • Grove RGB LCD
  • HMC6352 Compass
  • JHD1313M1 RGB LCD Display
  • LIDAR-Lite
  • MCP23017 Port Expander
  • MMA7660 3-Axis Accelerometer
  • MPL115A2 Barometer
  • MPU6050 Accelerometer/Gyroscope
  • Wii Nunchuck Controller

More platforms and drivers are coming soon...

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, require the github.com/hybridgroup/gobot/api package and instantiate the API like this:

  gbot := gobot.NewGobot()
  api.NewAPI(gbot).Start()

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

  gbot := gobot.NewGobot()
  server := api.NewAPI(gbot)
  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.
