Q&A says that as long as your base and / or drive train is touching the HDPE triangle then you are "in" the loading zone in an early answer. I would be suprised if there isn't more wheels hidden by the picture towards the front of the bot that makes it legally "in" the loading zone.

so it looks like you have a tetrahedron shape on your base where you can store and make your own stack of tetra. How many can you hold and stack at once? let me say it looks like a very nice bot.
