Connecting to Leap Motion


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, it will open a websocket connection in port 6437.
  • Connect your Computer and Leap Motion Controller.
  • Connect to the device via Artoo.


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

The main steps are:

  • Run the leapd daemon, it will open a websocket connection in port 6437.
  • Connect your computer and the Leap Motion controller
  • Connect to the device via Artoo


The normal Windows download of the Leap Motion software from should work with Artoo.

We are currently working with the Celluloid team to add Windows support. Please check back soon!


Check out our documentation for lots of information about how to use Artoo.
