Nice. Thanks for sharing.

Just another contrarian note for all these pivoting truck designs (this in NOT a criticism of team 48's design or any of the other similar designs we've seen -- you've implemented a very cool feature. Hats off to you. BUT...) You guys do realize that your tipping wheel base is the distance between the pivots of your trucks and not the distance between the first and last wheel, right?

I know you can do things to make this not be the case (have the truck axle lock up, implement a wheelie bar, etc.), but so far, all the pivoting truck designs I've seen have no obvious means of accomplishing that task.

If it comes to a pushing match with two robots, each with great traction, one with straight NWD and another with a pivoting truck design, it seems to me that that smart money will bet on the NWD machine tipping the other (or rather, the pivoting truck robot will have to call off the fight rather than continue to push and tip itself).

I'm just saying...
