I was wondering about the wording of the Minibot rules:
The FRC manual sec4:
R92"exactly one 12V rechargeable NiMH battery pack identical to those supplied in the FTC kit of parts (PN W739057)"
But
“No more than one HiTechnic DC motor controllers”
Since FIRST did not choose to say “No more than one battery”, are you required to have the 2lb battery on your Minibot?
I interrupt that rule to mean that all Minibots must have the battery on board. However that is something to ask the GDC for an official ruling on the Q&A.
With that being said, building a Minibot that climbs the pole with out a battery would be very difficult. Not impossible, but it is far more likely that all Minibots will use a motor and battery to climb the pole.
A solution that uses only the bending of material, surgical tubing or rubber bands as sources for stored potential energy would be very impressive.
note, the following statement is my opinion. it is not based on any sort of solid ground.
I assume that the GDC wants anyone who plans on building a minibot to use some sort of motor or electric devices to climb to the top. Although, just because you have a battery, doesn’t mean you need to use it.
FIRST has made a mandate for the use of the battery:
<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
Could anyone please upload or link to the battery’s specifications?
I’ve tried looking the part number (PN W739057) on google and browsed through several threads here on CD, but found nothing.
By Specification I also mean dimensions and weight.
This is a similar battery but 3.3 times the capacity. It’s also a 10-cell. So the dimensions should be similar but probably heavy than the 3000mAH pitsco battery.
Actually, we have a few of the 3000mAH batteries from our FTC team. I will measure and weigh them tonight.
