How high is that front wheel going to be? Keep in mind, if the bridge is balanced, it's a foot off the ground. If it's tilted the other way, it's 2 feet off the ground!
Personally, I think many people are overestimating the difficulty of driving up the bridges. Being around for both Rack 'N roll and Breakaway, I've seen how easy it is to go up a ramp with a normal kitbot design. the biggest problem teams had in those years was bottoming out transitioning from the ramp to the horizontal elevated portion. That's not a problem this year!
All three of these robots had more or less normal drivetrains, and that ramp is probably steeper than the bridge this year!
