It will split open at the front (the yellow thingy was temporary) as
detailed in the page:

I put a new picture of how I think it should open, but this is a mockup.
The first iteration can stack up to four but with a wraparound frame. This
new setup is just to see if I can build an articulated frame that can
"split", I still haven't figured out how to build it a) strong and b) drivable.
That's actually the hardest part, is thinking of a way to actuate the split.
I'm thinking of having an arrow shape that pushes slanted pieces from each
side, driven down by a rack piece, sort of like a plunger that splits the
sides apart.

Time is the key. It's hard to get into building after a long day... :)
Thanks for the words of encouragement!
