I NEED BUILDERS!!!

PPLEASE READ:
I'm planning a big adventure and I want to integrate MUCH vehicles (for example drones, lunar cars...)! So if you want your cool vehicle in it, just post or build one! Note that it shouldn't be bigger than the room in this level, otherwise I'm maybe unable to use it. It MUST have a cockpit, that the adventure robot can enter and leave. And please AVOID transmitters, if possible! If you want an example what I want, check out my Mini Miner!
As a bonus, the coolest vehicle gets a new subscriber ;)
