RoboMaster S1 - DIY

cults3d

2019.07.18 Printed, and it works flawlessly! I've got one fully compatible spare wheel right off the bat. The 'wheel hub' is the only tricky part to print (lots of overhangs no matter how you do it), so I've added designed-in supports to make it easier. Refined the other designs a fair bit too. This thing is ridiculously cool. So satisfying to have every roller click perfectly into place on the first prototype print. 2018.07.19 Heavily updated the hub to print 180º flipped from before, allowing for some needed geometry that was missing earlier. Prints great! I've now switched to printing with a 0.6mm nozzle for a huge improvement in print speed and strength. As a side effect, the added-in supports become tiny to slice/print since I'd designed them for single-width 0.4mm nozzles. If you want to use anything but a 0.4mm nozzle, you'll need to edit the 'printable' tab in the OnShape - I made a variable just for such things. The new Robomaster S1 is out, and it's an incredibly impressive design. BUT there aren't any spare parts available! I'm fixing that with my open-source S1 CAD modeling. Progress / completeness So far I've recreated my favorite part of the design: these incredible mecanum wheels. They're 12-wheel, 45º, and 96mm in diameter. They've got a unique internal rubber damper that effectively gives this robot freakin' suspension. More to come. Leave a comment with what you'd like to see. Using this in other robots If you'd like to use one of these wheels for your own system all you'll need to do is modify the wheel hub component to fit your motor - should be super easy.
