The Leap Motion is a user-interface device that tracks the user's hand motions, and translates them into events that can control robots and physical computing hardware.

How to Install

First install the Leap Motion Software

Now you can install the package with:

go get -d -u github.com/hybridgroup/gobot/... && go install github.com/hybridgroup/gobot/platforms/leap

How to Use

package main

import (
	"fmt"

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

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

	leapMotionAdaptor := leap.NewLeapMotionAdaptor("leap", "127.0.0.1:6437")
	l := leap.NewLeapMotionDriver(leapMotionAdaptor, "leap")

	work := func() {
		gobot.On(l.Event("message"), func(data interface{}) {
			fmt.Println(data.(leap.Frame))
		})
	}

	robot := gobot.NewRobot("leapBot",
		[]gobot.Connection{leapMotionAdaptor},
		[]gobot.Device{l},
		work,
	)

	gbot.AddRobot(robot)

	gbot.Start()
}

How To Connect

OSX

This driver works out of the box with the vanilla installation of the Leap Motion Software that you get in their Setup Guide.

The main steps are:

Run Leap Motion.app to open a websocket connection in port 6437.
Connect your Computer and Leap Motion Controller.
Connect to the device via Gobot.

Ubuntu

The Linux download of the Leap Motion software can be obtained from Leap Motion Dev Center (requires free signup)
