Team 1625 Minibot FIRST Run

[Chris27]

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

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!)

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

And then dance.

Are you sure that the gearbox is not considered to be part of the motor unit? I assumed we had to keep the stock one on but if we don't that could be a game changer.

That is a Q&A question if I've ever saw one, we were operating under the same assumption.

It would appear that somebody on 1625 keeps up with the Q and A...

Yes, or with CD: http://www.chiefdelphi.com/forums/sh...43&postcount=4

Also, according to the dynometer tests posted on this thread:

http://www.chiefdelphi.com/forums/sh...ad.php?t=89072

there is a 60+% output power bump (with 12V regulated supply) available by removing the gearbox.

Moreover, the motor with gearbox is about 210 grams, without about 130.

just a guess on how this might be able to happen and still be in the rules. Once the deployment starts the motors somehow pull some surgical to give it elastic potential energy. Start filming and release that tension and up it goes. I could be completely off but that's one way i can think of doing it.

edit -- nvm -- I totally forgot the gearbox itself contains the gears needed to make a custom gearbox -- just be careful since the pinion gears are fragile.

I heard Winnovation use a win pump. They hook both motors up to the Win pump. Right at the start of the deployment. The Win pumps then fill the robot until it is completely full of Win. The excess Win then bursts. They direct the Win through a nozzle that transmits the win and turns it into veritcal motion. Who said innovation was dead on the mini-bot race?

Where can we find a win pump?

At your local win-mart, or you could ask Winnovation if you could borrow one. I strongly believe that they actually use more than one on their robots year in year out . I'm sure they have extra's, gotta stay stocked up.

In the corner of their website, it says, "A Win Pump Company".

Please record the conversation you have with them as I am sure the advice you will get will be quite priceless.
