I would, too. I wasn’t responsible for this; it just appeared after we’d asked one of our mentors to take the lead in mounting the encoders. He likes his laser cutter.
This would’ve been designed in Microsoft Visio. I can try to get a look at the drawings some time this week and maybe even recreate the parts in Solidworks – but it’ll be, necessarily, a low priority.
It’s an 18 tooth sprocket that engages at both the top and bottom.
This is a pretty simple method, all things considered, since we have the laser cutter to work with. Manufacturing time might have been as long as five minutes. Development probably took as much as thirty minutes. “Traditional” methods would’ve involved manufacturing and adding a hard point to the chassis to fix the encoders in place and devising a system of gearing that connects to the existing drive components. Comparatively, this was a walk in the park.
