I'm not discouraged. If I were the type to get discouraged, I wouldn't be in FIRST. Last year was our best year -- FLR top seeded champions -- and the year before was our worst out of six... We're not the type to go packing just because we're frustrated!

That said, someone mentioned something about the HOSTBOT not being able to deploy the MINIBOT, and that has me worried that I've missed something... The HOSTBOT is permitted to push the MINIBOT onto the tower pole, right?

The HOSTBOT can provide horizontal motion for the MINIBOT, but it is illegal for the HOSTBOT t provide vertical motion to the MINIBOT.

They just are using magic

Well, then they are cheating. I don't see 'magic' on the allowable parts lists for mini-bots.

Okay, so the HOSTBOT can use horizontal motion to push the minibot onto the pole. That's exactly what I thought...

(Sometimes I am paranoid that I have missed some nuance that isn't nuance at all, and that everyone else got it because it is completely obvious, but for some reason we've missed it!)

ya, considering the only way the minibot can move up the tower is "solely through electric energy provided after DEPLOYMENT by the permitted, unaltered battery and converted to mechanical energy by the permitted unaltered motors ", I don't really see how this is possible without breaking a rule/having all necessary components on board...

For all the "haters" and non-believers:
The potential energy (for a minbot weighing 1.5kg) at the top of the tower minus the potential energy at the deployment line is about 34.4 joules
2.337m X 9.8m/sec^2 X 1.5 kg = 33.4 joules
According to this thread:
http://www.chiefdelphi.com/forums/sh...ht=motor+specs
the motors run at about 21 watts w/o gearbox at 14 volts. I believe that informtion is trustworthy and it is well documented, so I will trust it.

With two motors thats 42 watts total, so in theory, the bot could go up the tower is under one second. The video shows about 1.1 seconds from deployment line to top.
It's Possible

I am curious about what looks to be the turbocharger kicking in partway up the tower, that is odd. Could just be the angle of the view that makes it seem to go faster.

We were thinking of having Goku teleport our minibot the top....but he's too busy

Re: Team 1625 Minibot FIRST Run
 
Well it seems that our mini bots 3.5 sec time isn't good enough anymore.... o well time to add the second motor

Would it be possible to get a 1080p version of the video with slow mo and freeze frame action? Plus if it isn't to much trouble could you guys post the plans for the flux capacitor you guys also built?

What do you mean? it was listed right after the description of next years water game. Didn't you see it?

I'm just having issues with my MINIBOT team because it seems that variations on weight and gearing keep resulting in about 4s of climb time no matter what we do, and I'm about to brain myself on a wall in frustration!

No. What I mean is there just isn't a lot of stuff there; No big wheels, no unneccessary parts, no excess weight.

But it would take him over 9000 seconds to get it up there...

If I'm not mistaken, the video quality is deliberate to hide their design.

At least it didn't get stuck at the top!

I for one would really like to thank 1625 for posting this video. Around Jan 14th, a similar design (I am guessing) crept into my head but seemed too out-there. They could have waited until their first event, and just blown everyone away. Instead they have inspired my team to get more creative and aggressive in our mini-bot designs.
***************************
Anecdote Time:
In high school, I competed in Supermileage in Indiana. The first year my team competed, we got 169 mpg for our best run. The winners got over 500 mpg. The next closest was 300 mpg, so we (being the cocky HS kids we were with bruised egos) were conviced that the winning team was "cheating". 6-7 years later, my old high school placed second with just over 1200 mpg with a perfectly legal design. That was an especially good year, but most good teams could get 900 mpg or better. Nearly 2x what we considered "cheating" level performance.

When you call others "cheaters" for doing exceptionally well at things, it can really hurt their feelings. It also makes them less likely to share future successes. This is a loss to the community.
**************************
Again, nice job 1625, and thanks for sharing. I for one was quite humbled yet quite inspired. This 3 second video resulted in my first sleepless night of the season.

I did show this video as inspiration to my MINIBOT team... I'm not sure if they're inspired or just overawed, but it certainly gives us all something to shoot for!
