Does it rely on the flex of that aluminium bar?

It’s a solution our lead design mentor came up with. It’s in that aluminum block the cylinder connects to. Sorry for being vague I’m not sure how much I’m allowed to give away.

And to rutzman, we chose that as a way to both make the length of the module shorter and naturally geared 2:1 and whatever we choose for our sprockets on the wheel. As far as side loads in the traction wheels are concerned we haven’t had a real problem they were made very sturdy and shouldn’t be a large issue. All the ratios, other than the obvious 2:1 from the wheels, are classified. Sorry.

FYI. im mentoring on 3547, i used to mentor for frog force (503)
