Ramp parking

When parking bots on the ramp, may tires be up on the lip of the back of the ramp?

Generally speaking, bots considered ‘parked’ as long as nothing is in contact with the floor, correct?

Yes, the official wording says: “Parked – A Robot is Parked if it is touching the Ramp and not touching the Floor at the end of the Match.”
No matter how many wheels are on the ramp, no matter if the robot is hanging over the cliff.

@nenik, thanks!
