3D-Printed
ESP32 Claw
A 3D-printed robotic gripper driven by an ESP32 and a continuous rotation servo. It broadcasts its own local Wi-Fi access point and serves its own web dashboard — no router, no internet, no app store, no latency.
The neat part
The controller in the video isn't an app — it's a webpage served by the claw itself. The ESP32 is simultaneously the motor driver, the Wi-Fi network, and the web server.
