Vacuum robot ramp - customizable

I created a customizable vacuum robot ramp.You can adjust:heightwidthdepthadd a plateue (good to fit the ramp under the door and enable the robot to climb the remaining doorstep).add steps for a better gripI added a 3D-printed hinge ring to raise the door as much as possible and glued the ramp to the PVC floor.It decreased the doorstep by ~1.5 cm and enabled my robot to climb it.
