Building Specifics for Minibots

[pathogen4815]

Hey this is President of Team 1318 in Washington, while reading the rules on mini bots and parts you can and cannot use to build them. It seems that your robot is required, according to the wording of the list, to have a 12v battery but nothing else. It is stated in <R92> that while you may have up to two motors or up to 1 motor controller, you must have exactly one battery, regardless of if you need it or not. So i would like some clarification if any on if the battery is neccesary, and also as a side question, does it say in the rules anywhere whether the minibot must....
A: be touching the poll
B: stay at the top after hitting the sensor

Any help would be much appreciated!
