Introducing the ESP-ROLL - a Self-balancing Spherical Robot based on an ESP32 camera that you can build and have fun rolling over various types of terrain! 🟠📷

This little RC ball bot rolls in a transparent ornament shell, is 3D printable, and controlled over WiFi right from your phone - no fancy transmitters or complicated setup needed. You’ll be able to roll it around and stream live FPV video to your phone as you drive it.

In this video, I show you exactly how to assemble, wire up, and program the whole thing step-by-step.

👇 All the files - code, schematics, PCB gerbers, and part list are linked below so you can start this project right away.
