Re: Category A Crossing?
you just need an arm or two to push the cheval's ramps down and hold them down till you get wheels on them. Depending on how tall you are, you could use the same arm for lifting the portcullis. Main thing on the portcullis is lifting it enough to start going under, then having a smooth surface on top of your robot for it to slide over.
