Free 3D Files

Ready to print

Step 01

Get the files

Every design’s 3D files are a free download, with a ready-to-slice project alongside the raw STLs. No account, no paywall.

Free STL + 3MF
0.2 mm layers
PLA / PETG

Step 02

Print & assemble

The guide lists every printed part and every screw with its exact quantity, in assembly order — so you find out what’s missing before you start, not halfway in.

Exact part counts
Standard metric hardware

Step 03

Drop in the board

Each robot has a controller board made for it — hand-soldered, tested, labeled header per connection. Or take the KiCad files and make your own.

Labeled headers
No breadboards
PCB files included

Step 04

Flash & control

Arduino firmware goes on over USB or over the air. From there the robot hosts its own WiFi — set it up in the browser, drive it from your phone.

RookiDroid workshop bench — robot builds in progress

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.
