Unity AR/XR Factory Floor Example — Meta Quest 3 / 3S

A virtual factory-floor XR experience built in Unity 6 (6000.0.32f1) for the Meta Quest 3 / 3S, using an Edge Impulse vision model to inspect products on a moving conveyor belt.

Bottles travel along a conveyor. A virtual inspection camera runs an Edge Impulse FOMO object-detection model (bottle-cap detection). Bottles whose cap is classified as cap_incorrect are flagged as defective: a reject arm shoves them off the belt and they smash on the floor, while cap_correct bottles pass through.

Working demo. On-device Edge Impulse inference runs both in the Unity Editor (the XR simulator) and on the Quest 3 / 3S. Download the APK from Releases to try it on a headset, or follow the step-by-step tutorial.

Walk the floor and pick a bottle off the line to inspect it in your hand (watch the video):

Edge Impulse model

• Public project (clone it yourself): https://studio.edgeimpulse.com/public/751472/live

• Task: object detection (FOMO)

• Labels: cap_correct, cap_incorrect

  

The model is deployed as a C++ library and compiled to a native plugin for each target platform. See Edge Impulse's Deploy your model as a C++ library.

Note: never commit your Edge Impulse API key. Keep it in an environment variable or an untracked file (see .gitignore).

Download & try it

A nightly APK is built automatically by GitHub Actions and published on the Releases page. Download the latest .apk and sideload it:

adb install -r FactoryFloorXR-nightly-latest.apk

See docs/CI-NIGHTLY-BUILD.md for the CI setup and the repository secrets required to enable the build.

Requirements

• Unity 6000.0.32f1
• Meta Quest 3 or Quest 3S (Android build target)
• Packages (already in Packages/manifest.json):
  • Universal Render Pipeline (URP)
  • XR Interaction Toolkit 3.1.1
  • XR Hands 1.5.0
  • OpenXR 1.14.1

Project layout

Path	Purpose
Assets/Scenes/FactoryFloorDemo.unity	Main demo scene (build scene), assembled at runtime by FactoryDemoBootstrap
Assets/FactoryDemo/Scripts/	Conveyor, inspection, reject arm and Edge Impulse glue
Assets/Factory Conveyor/	Conveyor models, materials and prefabs
Assets/Bottle/	Bottle + broken-bottle prefabs and scripts
Assets/XR*, Assets/Samples/	XR rig, hands and interaction samples

Testing in the simulator

The scene can be exercised in the Unity Editor with the XR Device Simulator (from the XR Interaction Toolkit) — a mouse/keyboard-driven HMD and controllers — so you can validate the conveyor and inspection flow without a headset.
