RoboMaster S1 - DIY

thingiverse

2019.07.18 Update: I've successfully printed the spare wheel, and it works beautifully! One compatible spare wheel is now available. The only challenging part to print was the 'wheel hub' due to its extensive overhangs, so I designed-in supports for easier printing. I've also refined the other designs significantly. It's incredibly satisfying to see every roller click perfectly into place on my first prototype print. 2018.07.19 Update: I've heavily updated the hub design to print 180º rotated from before, allowing for necessary geometry that was missing previously. Prints are coming out great! I've now switched to printing with a 0.6mm nozzle for improved print speed and strength. However, this change has resulted in the added supports becoming too small to slice/print since they were originally designed for single-width 0.4mm nozzles. If you want to use anything but a 0.4mm nozzle, please edit the 'printable' tab in OnShape, as I've made a variable specifically for this purpose. The new Robomaster S1 is an impressive design, and it's hard not to be impressed by its incredible mechanical parts. However, there are no spare parts available yet! To address this issue, I'm creating open-source CAD models for the S1. Progress/Completeness: So far, I've recreated my favorite part of the design: these remarkable mecanum wheels. They're 12-wheel, 45º, and 96mm in diameter, featuring a unique internal rubber dampener that effectively gives this robot freakin' suspension. More to come soon! Please leave a comment with what you'd like to see next. Using This in Other Robots: If you want to use one of these wheels for your own system, simply modify the _wheel hub_ component to fit your motor. It should be super easy. CAD Design Source: I've designed this in Onshape. Here's the public document where anyone can fork and extend the design free of charge.
