Put the Tire Up

Hi everyone, this model has a tire inside it, to complete the mission the robot has to open the front door, which becomes a ceiling (this could be some points), the door can be opened on both sides with two different mechanisms. Then the robot has to pick up the tire (maybe it could worth some more points) and put it on the roof (this could be more points), now it has finished the tasks. All the dimensions are under 30 cm and the ceiling can support much heavier weights than a single tier before falling in the starting position. I built it to achieve great stability and resistance, hope you'll like it!
