I have a Raspberry Pi. I have a 3D printer. I have a Quest 3.

I had a simple thought: can I make something that combines all of them? That is how this project started.

Powered by Gemini 3.

Technical route:

1. Stream two video feeds from the Raspberry Pi.
2. Gimbal.
3. Chassis.
4. Quest remote control.

Finished dual-streaming. The latency is basically nonexistent, although for now it is still connected through Ethernet.

The current plan is to use a driverless-board approach.
