Looks awesome, but is the wheel cutout in the bellypan big enough to take the wheels out without taking the shaft and chain off? Then again you won't be swapping out colsons much, if at all.

We are doing something just like this, it looks scary similar haha.

Re: pic: 319 Octagonal Drive Isometric
Are you worried about something coming under your bumpers and hitting the chain/sprocket?
Also, it seems like the 2nd frame is a LOT just to support the bumpers. Assuming similar bumper rules as previous, something inplane with the existing drive frame could support it for far less pieces/weight/fab. |

I am think that structure is supported so well for the possibility of that being a second tier and not just bumper mounts. |

Why have a 2nd tier? The superstructure can mount to the drive frame. |

I put the second frame that high so that it was supporting the middle of the bumpers. Since the bumpers are as low as possible, I was worried about the moment created when running into a robot with the bumpers in the higher end of the bumper zone. |

This strikes me as a prime candidate for belt/chain in tube, in order to protect the chain. It also means the cantilever lever arm on the middle wheel won't be as long.

This isn't really a specific question for the drivetrain, but I've been working with the same gearboxes and I was wondering how you are supposed to mount them. Do you just use the bolts from the standoffs in the gearbox?

Octagonal Drivetrain! Its been a long time since I've seen a good picture of one.
179 did it ?first? in 2005. (Wow I'm surprised I commented on that one too). It was a pretty great robot too. Remember, that was 2005 BB (Before Bumpers Era). A couple things I'd recommend:
