Re: pic: Butterfly Drive

Hm... so I think the main issue revolves around when the tractions are down and the robot gets hit on the side, which might damage the modules, and the shaft especially over time. In addition, the way the piston is mounted probably also causes it to receive a lot of force on impact.

I might consider another design of the Butterfly, although I might move on to intakes or something other than drivetrains, because I've been doing that a lot. But anyways, here's what I was thinking about the new design:
  • Module goes into a 3x2 boxtubing; there I can maybe make the modules almost as wide as the interior of the tube to have minimal flex and bending (this is my logic to this problem, but I might be wrong...)
  • Pistons push down on the modules without any special mounting, similar to Neutrino's design
  • Change in material of the module plates. Maybe something like polycarbonate? Not really sure on this one: I know polycarb is flexible, but to some extent
