Of course there's always the fuse that blows if it happens in the reverse order.

Yeah your thoughts are true. Today was our first time running the minibot on the pole. We are still developing it though. We also were running it on the standard robot battery, rather than the small battery meant to be used on the minibot. We still have to cut some weight and program the minibot, so things might change.
