Is it appropriate to disconnect pneumatics pipe to rocket mini bot up pole?
No
According to:
<G19> 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).
In other words, that would be highly inappropriate.
Rule <G19> says no to launching the minibot, and breaking the rules is frowned upon…
Reading the rules, on the other hand, is mandatory.. ::rtm::
