Use of springs on the mini bot?

[Grim Tuesday]

The first team update covers this: The only acceptable form of stored energy (for vertical motion) is the battery pack.

<G19> After DEPLOYMENT, MINIBOTS must remain completely autonomous and move
up the POST solely through electric energy provided after DEPLOYMENT by the
permitted, unaltered battery and converted to mechanical energy by the
permitted unaltered motors (and associated, appropriate circuitry).
Violation: The TOWER on which the MINIBOT is DEPLOYED is disabled. If the
MINIBOT is not deployed DEPLOYED on something other than a TOWER, then
the ALLIANCE’Ss TOWER upon which the highest RACE SCORE was earned
will be discounted
