[Superllama12]

We were debating this, and we raised this question; however, we came to the conclusion that if anything were left at the bottom at all, it would definitely exceed the 12" dimensions on the minibot. Good luck!

EDIT: Just found this in the rules:
<R101> If a MINIBOT is rejected by inspectors due to a safety issue or concern related to the team’s method of storing energy, the concerned items must be disabled or removed from the MINIBOT before it can compete in a MATCH. The team bears the burden of proof that such a rejection is not valid. Teams should be prepared to provide justifiable test data or calculations during inspection to support their design.

Storing energy in the form of pneumatic pressure or a spring to launch it is probably considered, as someone said before, a safety violation
