Re: Team 1625 Minibot FIRST Run

I'm seriously going to worry the next two weeks about this one. Anyways, awesome minibot guys. Can't wait to really see it when you guys actually unveil everything.

Can you please refer to the rule that requires the battery to be attached to the minibot?

There is no rule that says there must be a battery. Of course, if you want it to move, it is a good idea to have one!

Unless you have the energizer bunny as your minibot, it'd be hard to convert electrical energy to mechanical energy without a battery.

Re: Team 1625 Minibot FIRST Run

Actually, there IS a rule that says you need to have a battery:

<G19> MINIBOTS must remain completely autonomous and move up the POST solely through electric energy provided after the start of DEPLOYMENT by the permitted, unaltered battery and converted to mechanical energy by the permitted unaltered motors (and associated, appropriate circuitry).

Sure, R91 says that the minibot can't exceed 12x12x12 inches:

<R91>The MINIBOT may not exceed a 12” x 12” x 12” volume and weigh no more than 15 lbs. MINIBOTS will be inspected for the volume constraint by being placed in a five-sided box with internal dimensions of 12" x 12" x 12". If the lid (the sixth side of the cube) does not seat properly, the MINIBOT does not pass this part of the MINIBOT inspection.

This size constraint on the minibot remains in effect throughout the match; this was stated by the GDC in a Q and A forum post:

http://forums.usfirst.org/showthread.php?t=16288

This would seem to preclude tethered batteries.

Re: Team 1625 Minibot FIRST Run

ok but does that mean that the battery has to be attached to the minibot by zip ties or can it just be hanging from it?

Re: Team 1625 Minibot FIRST Run

the 12x12x12 box rule still applies so the battery couldn't dangle much

Re: Team 1625 Minibot FIRST Run

Awesome video! And an awesome precedent to set - this video will serve as inspiration to anyone who wants to push their minibot to the max this season!

What I saw/inferred:

* Two motors, with transmissions removed/modified/replaced with custom transmissions that are lighter, more efficient, and geared to be faster.

* Custom direct-driven wheels/rollers that I'm sure are almost weightless (they can be tiny because of the faster gearing). Going out on a limb...lexan and split surgical tubing as the tread?

* Just enough structure and electronics to hold it all together and get it to go.

In a "spec racing" competition, he/she who builds the lightest, most efficient machine wins. (Or he/she who cheats but doesn't get caught wins, but I'm sure that isn't the case with this crowd!)

Re: Team 1625 Minibot FIRST Run

I assume that, when the time comes, Winnovation's minibot will simply teleport to the top of the pole.

And then dance.
