Re: pic: Frop Drives

Very cool! I love how compact the bevel gear makes the system. I've always admired your team and your somewhat unconventional creations, even if they don't always work out quite right. Your 2010 drive comes to mind as well.

What was the rationale behind the multiple rollers rather than a single traction wheel? It looks like it may have compromised your belt tension through inadequate wrap, and as you said, the friction from all the idlers wasn't doing you any favors.

How high were the traction rollers actuated off the ground when in mecanum mode? On similar systems, I've seen teams underestimate how high the traction wheels need to be raised to get them out of the carpet, which causes drag and slows the mecanums down. Plenty of teams manage very fast mecanum drives on four CIMs, so I feel like something else may have been in play.
