You need a platform at floor level, supports that hold your frame above the ground such that your wheels are exactly tangent to that floor, and holes in the floor so they don't touch the wheels. Big ones, so they don't catch if the robot shakes.
It's really not as simple as some 2x4's with a plywood surface in the front. I'm not saying it's necessarily a crazy complex engineering challenge, but it's not trivial, the design is different for every robot, it's a big part that takes up a ton of pit space, and it's just far less effort than unplugging some breakers. If you don't trust your team's electrical practices enough to be able to do that, your electrical system may be a much bigger safety issue than wheels on the ground.

I see your point and I may try to make some improvements. This model does work with our robot because our elevator doesn't go lower then the top of the chassi. I may put a sideways 2x4 on top of the existing 2/4 to make it so it's completely level but that would be for other teams. I'm the electrical guy and I see why you would just pull breakers but those things are kinda hard to pull off in a hurry (if they are properly installed they are tight) and this is more of a proof of concept then a done project.
