normal, so not quite 4" tall - we are quite worried about a “real” barrier and are looking to build one, the 4x4 test was kind of impromptu - the bot has did well so hopefully things go well with the real barrier
how are teams building a real barrier?
Ours isnt real, but we put some 2x4’s together and fleshed out the remainder with 1/2 inch plywood. I realize it isn’t metal, but it gives us the right dimensions.
We just did the same thing and it still goes over. I am worried about the metal version. We’ll try that this weekend.
So you guys are building a metal one? 
may have to make a visit then
Nope, thinking about finding out where LM sets up a complete field.
