Earlier this week, while we were running tests with our robot, we unexpectedly had some issues going over the rough terrain... We had previously just been driving quickly over it and had no issues. However, we realized that there are going to be times when we find ourselves moving over defenses more slowly, so we were running some tests - and found that, about 20% of the time, we got into a nasty "tortuga."

Thankfully, we were able to make some minor adjustments to the skid plate and weight distribution to overcome the problem. (We were really worried, we'd have to move the bottom of the robot up 2" - which would be brutal as we are designed to go under the low bar and space is already really tight....) Still, that defense definitely proved nastier than we had expected. Anybody else have similar experiences?
