The Story

Engineering Meets Play

Hi, I’m Zhengyu Peng — an automotive radar engineer at Aptiv by day, robot builder by night. RookiDroid started as a personal project to build 3D-printed robots for my kids.

The controller boards you see here are extras from my own builds — each one hand-soldered and thoroughly tested. What began as a hobby has grown into a workshop where I share designs, code, and hardware with fellow makers around the world.
