Here are my concerns though: 1) How do I make sure the shroud doesn't touch the ground, thereby violating <R06>, and 2) Will this even work to a good extent? Will there be too great of a loss of vacuum?

Additionally, I envision that the fan in the vacuum generator would suck air from under the robot and blow it out above it. Am I right in making this assumption?

Thanks!

I believe the reason why 1771 was able to create so much force was becuase they had an excellent seal on the ball.

F = P x A

So if you can gradually build up pressure over a large area you can create a lot of force.

But without a seal on the floor, it'll be pretty darn near impossible to build up pressure.
