Re: Team 1625 Minibot FIRST Run

Hmmm,

Based on the sound from the video, it seems like your storing energy from the motors prior to the start of the video. This would infact give you that crazy fast launch, however, because of Team Update 5, you cannot start storing energy until after deployment starts. So yes, your minibot climbs fast, but you need to increase the time to include the time it takes the motors to wind up.

No, 1625 isn't cheating in this video - just because it's really fast doesn't mean a rule was broken.

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.

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.

Re: Team 1625 Minibot FIRST Run

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.

Re: Team 1625 Minibot FIRST Run

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.

Re: Team 1625 Minibot FIRST Run

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.
