DJI RoboGOD- BIG Robomaster S1 Wheels

Turn your DJI robomaster into aROBOGOD. Yep, that's what I'm calling it.

The stock mechanum wheels are 100mm diameter. These are 130mm, a nice substantial bump up in size (130%!) that gives you better off roading, higher top speed, and extra awesome-factor.

They use the exact same hub, dampener, and rollers the original uses so the list of need-to-print parts is lower. (I've made a drop-in printable hub and TPU dampener design too if anyone wants..). The stock wheels have 12 rollers per wheel, these have 16. You can find rollers on eBay super cheap OR you can print your own replacement and even spray plasti-dip on them for ruberization that rivals the stock rollers!

Design Files & Open Source! ⚙️🔧

Everything is designed open source in OnShape so,for free and in a browser, you can, modify, remix, and download your own versions. Add text to the wheel outsides? Easy. Make them 150mm instead? EASY. I've already made the diameter and roller count a variable and everything self-adjusts.. Magic.

Here's the OnShape document.

Also feel free to ask me for any variations/customizations, happy to help.

Design: Why not even larger ‽‽

Why stop at 130mm?I didn't actually. My first attempt was to make somemonster 200mm wheels with custom printed rollers, wheel bodies, hubs, AND flexible TPU dampeners. 🤯 .. They don't really work. It's the very maximum size that the body can fit but the PID stabilization the robot uses gets super thrown off by the 2x diameter. It overshoots and oscillates and drives like a drunk. And they were a CRAZY amount of work making.. I don't recommend it at all.

Printing 🖨 ==========

Printing this works great in PLA and works well in PETG. In PETG it's close to too flexible but it's fine.. but honestly not worth the extra difficulty in printing– so I'd stick with PLA.

Designedwith a 0.8mm print nozzle in mind! 😄 These are big-ish parts, and each full wheel takes ~12h to print with the standard 0.4mm nozzle. Swap in a larger nozzle that costs less than $0.50 and print it over 2x faster. Almost any layer-height works. I do recommend a glass bed for that shiny bottom later (that's the outward-facing part of the wheel) but that's only for style.
