Tiny ESP32 Robot Roams Your Desk Like a Curious Pet

Open-source companion bot reacts to touch using simple, low-cost hardware

A tiny robot built by YouTuber Tech Talkies quietly wanders across a desk, then pauses when you give it a gentle pat.

The DIY companion runs on an ESP32-C3 Super Mini and features two N20 geared motors driven by a DRV8833 controller. A 1.3-inch OLED face shows playful expressions.

It’s simple. Delightfully so.

With 3D-printed parts and open-source code, the project shows how surprisingly approachable personal robotics has become.
