XRometr


OAK-D based Mixed reality construction kit

Photo of a assembled Skakun XR Moduel


XRometr is a fully open source modular mixed reality solution. It is made with researchers, artists and developers in mind. Project provides a base for further incorporation of external sensors and libraries. Current version uses inertial sensor for head tracking and aruco library for anchoring digital content to the physical world.

Hardware


  • Depth AI OAK-D depth camera with neural processing unit (Series 1 )
  • Chuwi LarkBox Pro micro PC
  • Powerbank Battery capable of providing at least 90 w of power (12v and 3a) for mobile version and 12v 1.5 a for headless mode.
  • powerbank starter module set for requesting 12v, reference units would be PD2721/IP2721 chip or ZY12PDN mulitester
  • 5.5 inch fullhd hdmi screen from DFRobot
  • 3D printed cover for computer unit and the screen
  • bluetooth controller pad ( optionally )

Printables

  • Screen and sensor enclosure
  • x-connector attaching screen and sensor to the enclosure
  • additionally the 5x20 any metal screw is needed to secure x-connector

Power for standalone and mobile setup


  • XR and mobile needs powerbank with the following specs :
    • 12v and 3a minimum
    • adapter with starter module for requesting precise 12v for Chuwi Larkbox Pro (may vary depending on what type the computing unit is being used)
  • Headless setup, without display powered from the same source can work with lower tier powerbank that can provide 12v and 1.5 - 2a .
  • Standalone will work with powerbrick

Software


Current version runs on Python backend and is rendered using Panda3D engine. Additional libraries used for image processing and marker detection are Opencv-contrib with Aruco module. Numpy and Scipy for mathematical backend.

PRINCIPLES OF SUSTAINABILITY


3D printing matherials:

We use biodegradable filament: B2A-834A1 | F3D FILAMENT Bioflex - 1,75mm or F3D FILAMENT PLA 1,75MM

Printing and packaging:

We print only with with eco-responsible produced EBS-260 hand printer our no-waste box for Xrometr
