I'm putting it out there and betting the majority of teams who weren't around for 2004 who try to climb over the barrier will end up like below.
You need to plan for worst case scenario, other robots contacting you and obstacles in your way as you try to traverse the barrier, if you choose to go that way. Trying to cross the barrier in your lab in a best case scenario would be as effective to your team as practicing your robot shooting at the hoops using a football.
Oh and for those of you who think you will not have damage to your robot if you just try to plow over the barrier at high speed, I suggest you do a real world simulation of this. Go find yourself some road hazard strips like this
(or a simple curb) and feel the result of going over those even at 10 MPH. I think you will be surprised at the second thoughts you might have at just plowing into the barrier then.
