I was just thinking that, in well over a decade of FRC, I've never seen a 'bot leave the field under its own power.

But then we've never had a game that drove the majority of robots to be shorter then the aluminum tube that makes up the 'top' of the field barrier. Combined with contemporary high power, high traction drive trains I'd guess a good impact from any of the many low robots would be enough to pop that panel out. I haven't put together a field in a long time, so I don't remember how those panels are secured, but I doubt it was ever expected to resist a 100+ pounds of robot at 10+ feet per second.
