Re: Under 1 sec mini bot
 

Being that we all have the same maximum power output (motors).
-Eliminate wasted power (friction, ect.)
-Decrease the amount of work that needs to get done (weight)


As per the topic:
I think it could happen. I haven't run any numbers to see if the motors + battery could make a mini-bot go up in sub 1 second in ideal conditions. My gut ways it could. As per the deployment, it can be done quick, say .25-.5 seconds.

So, by one of the best teams in the world, I think it can happen once or twice. 1.5 seconds seems much more obtainable for the powerhouses, with 2-3 seconds being fairly "norm" for all highly ranked (top 20) in each division this year at championships.

Re: Under 1 sec mini bot
 

Gearing, weight, and size of wheels. Our current minibot is going up in 2.6 seconds. We are going to put on smaller wheels and re-cnc the plates to make them smaller and lighter. http://www.youtube.com/user/frc3467?.../0/fkd1pkthJZY

I think we will see a 1 sec or close to minibot.

Re: Under 1 sec mini bot
 

Minibot speed is all about getting the gearing and traction right.

Re: Under 1 sec mini bot
 

Oh, the wheels are directly attached to the motor shaft... So that is not a good idea?

Re: Under 1 sec mini bot
 

We geared ours for a 3 to 1 ratio. Some teams have opted for just direct drive to eliminate parts to make it lighter.

It is all about finding a balance!

Re: Under 1 sec mini bot
 

Not necessarily. That could be fixed as part of your design.

Re: Under 1 sec mini bot
 

Sub 1 second? No.

I do however think that as the season goes on more and more teams will see "how its done" with the minibot then the game will undergo a shift from a Minibot heavy game in the first three weeks to a tube heavy game at championship as the minibots become more even.

Einstein will be a battle of who can put up the tubes and who can hit the button the fastest to deploy their minibots.

Haven't seen 469 yet though.........

Re: Under 1 sec mini bot
 

We've been trying to improve our minibot (which won top honors at the RaChaCha Rally in the Minibot Race), but have had a very hard time pushing under the 2.5 second climb + deploy mark...

Everything we have tried to get it to go faster hasn't had the torque to climb, and perhaps there is something we are missing. It wouldn't surprise me!

Re: Under 1 sec mini bot
 

I am confident we will see a minibot get to the top in less than 1.4 seconds. Yes, 1.4 seconds including deployment.

I will bet a Mountain Dew on it. Any takers?

Re: Under 1 sec mini bot
 

I have to agree with you Paul. I think including deployment you will see the 1.2 sec mark pushed.

Re: Under 1 sec mini bot
 

It's an estimate from youtube quality video, but 118's minibot appears to climb in very nearly 1 second exactly.

Re: Under 1 sec mini bot
 

I'll bet a Mountain Dew that no minibot will hit the top of the tower at the 8.6 second mark in a match (1.4 seconds from 10.0).

That said, I agree with the "spirit" of the bet and believe 1.3 and 1.2 second minibots will happen.

Re: Under 1 sec mini bot
 

I will up Pauls bet for you if the 1.4 sec mark is not hit i will buy you a throwback Mountain Dew.

Re: Under 1 sec mini bot
 

If you'll be at FLR, I'll take that bet, with the added rule that it is a minibot from a team other than 217 and at FLR :p

Re: Under 1 sec mini bot
 

That's a sucker bet...I'm guessing that Paul has a very good reason to believe that 1.4 sec is obtainable. Say, oh...I don't know, maybe he's seen his own robot do it???
