Re: Team 1625 Minibot FIRST Run
They just are using magic

Re: Team 1625 Minibot FIRST Run
Well, then they are cheating. I don't see 'magic' on the allowable parts lists for mini-bots.

Re: Team 1625 Minibot FIRST Run
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...

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. |

Re: Team 1625 Minibot FIRST Run
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? |

Re: Team 1625 Minibot FIRST Run
What do you mean? it was listed right after the description of next years water game. Didn't you see it?

Re: Team 1625 Minibot FIRST Run
No. What I mean is there just isn't a lot of stuff there; No big wheels, no unneccessary parts, no excess weight.

Re: Team 1625 Minibot FIRST Run
But it would take him over 9000 seconds to get it up there...

Re: Team 1625 Minibot FIRST Run
If I'm not mistaken, the video quality is deliberate to hide their design.

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

Re: Team 1625 Minibot FIRST Run
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. |

Re: Team 1625 Minibot FIRST Run
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!
