XR-Robot-Teleop-Client

XR-Robot-Teleop-Client is a robot teleoperation client for VR/AR headsets built in Unity. It uses Meta Movement SDK to obtain upper body poses (via inside-out body tracking) and sends it to a user-specified IP address via WebRTC.

XR-Robot-Teleop-Server is a companion project written in Python that receives the body pose data. You can define custom callback functions (which are invoked every time the data is received) to visualize body poses or integrate into a robotic simulator.

Instructions

Installation

Option 1. Using Meta Quest Developer Hub

This requires developer mode to be enabled on your Quest device. Refer to the instructions here.

• Download the latest .apk file from releases.
• Connect your headset to computer (via USB-C).
• Open Meta Quest Developer Hub and click the 'Devices' tab.
• Drag & drop the .apk file into the right-hand-side of the screen.

Option 2. Install from Meta App Lab

TODO: We have not yet uploaded the project to App Lab — we will do so soon!

Usage

• Obtain the IP address of your computer.
  • If the headset and PC are in a common network (e.g., same Wi-Fi router, university network, ...), you can generally use the local IP address which you can find by running ipconfig.
  • If the headset and PC are in different networks, you will need to perform the routine process (of setting up port-forwarding, opening firewall at a specific port, obtaining public IP, ...).
    • If you are unfamiliar with this, Tailscale is highly recommended—it greatly simplifies this process while providing rigorous security.
• Setup XR-Robot-Teleop-Server Python package and clone its repository.
• Run one of its example scripts (e.g., 360-unity-teleop.py).
  • Wait until it finishes loading and says: TODO.
• Open XR-Robot-Teleop-Client and enter the IP address of the PC, then press the connect icon.
• Voila!
