Won't this break the bumper rules? You won't be able to have 6" of bumper on the front corner bumper perimeters. Or am I misinterpreting the rules?

<R08> P. BUMPERS must be mounted to the ROBOT within the BUMPER ZONE, and must remain there. The BUMPERS must not be articulated or designed to move outside of the BUMPER ZONE.

That subject has been discussed quite a bit on this and other threads....how about comments on the driving part of the robot? :)

I'm glad to see 842 has their robot driving around, this drive system is quite a departure from their past robots.

Ah, sorry about that. I was just interested in case it was legal :P

could have proved useful

That is GORGEOUS

I love the structurally sound mounting of your wireless bridge! Hey, it beats ours, right now ours is just wedged between our cRio and the PD block.

That is a NICE frame! Can't have traction? Convince the robot it's a tank, and the mind-over-matter problem is solved!

As for the rear differential assist, does it work well? Have you tried 4-wheel Ackermann (where the rear wheels turn the opposite direction from the front wheels)? That way, all of your wheels would be pointing more in the direction you want that part of the robot to go, so there would be less slipping. Or is that all compensated for because of the trailer? When we were testing with a differential drive train, we realized that the #1 reason the wheels slipped was that they were going different speeds. If we were trying to go forward, if we accelerated at a medium rate with both of the wheels going EXACTLY the same speed, we could actually get some pretty nice speed, but if one is even SLIGHTLY off, the faster side slips and you slow down.

Seriously nice and STRONG chassis there!
