What's in the kit
Every component, sourced and spec'd for the M4-D2.
The robot base — differential drive, 9 kg payload, autonomous docking, ROS 2 native. The foundation everything else builds on.
140 W output — enough to run a Mac Mini M4 at full throttle. 24,000 mAh gets you 4–6 hours of untethered operation.
Curated Technic pieces — pre-kitted for the M4-D2 frame. Mounts to the Create 3 top ring, creates a stable shelf for the power bank and Mac Mini. BrickLink Studio file included.
Custom 3D-printed PLA+ cradle — precision fit for Mac Mini 2024. Holds the Mac Mini securely without blocking any ports.
M3 and M4 bolts, rubber grommets, and adhesive strips for attaching the Technic frame to the Create 3.
One for power (power bank → Mac Mini), one for data (Mac Mini → Create 3 USB-C adapter). Braided for tangle resistance.
Step-by-step build instructions with photos. BrickLink Studio file for the Technic superstructure. PDF delivered by email.
Open-source ROS 2 bridge — runs on your Mac Mini and lets you drive the Create 3, read sensors, and send it home.
* Mac Mini not included. Compatible with Mac Mini 2024 (M4, M4 Pro, M4 Max).
The M4-D2 Mobility Kit puts your Mac Mini on wheels. Robot base, power supply, Lego Technic superstructure, Mac Mini cradle, mounting hardware, and open-source control software — all in one box. Plug it in, build it out, and your AI is mobile.
