So coopertition is not a big thing for you? I mean, you won't be lending your minibot out to other teams, or will you? Scouting reports will likely tag your team as "keep 'em away from the pole" even if for only a few seconds. We're considering a tinted polycarbonate box which may or may not have a minibot aboard. How fast? Thaaaaat fast! wanna see it again? :)

Yes. We have had about 4 prototypes, all along the same lines. No final product has been created, but proof of concept has been shown. We figured that since it is such a huge part of this game, it was necessary to spend a significant amount of time on it.

I agree that the toughest part would be to create the deployment system also. Depending on what teams use to start the minibot, it will be very tough to fabricate something at competition that deploys it, or even modify their current design to allow for the new minibot.

Q.E.D.

(unless you are including the start of deployment as well?)

The only problem is you guys don't have the battery on in that video, that battery is very heavy and will slow you down. Also if you were thinking of leaving the battery on your FRC robot just remember the 12x12x12 rule won't let you do that.

Re: under 2 sec Mini bot

Does anyone have specs on the TETRIX motor with the gearbox removed?

I would check the legality of that in the Q&A. In the current context of the rules, it seems like it may be legal to remove the gearbox, but it's better to be safe than sorry.

Q&A has ruled that it is legal.

Re: under 2 sec Mini bot

So with the max power outputs of the motors and the weight of two motors and a battery, you could calculate the absolute maximum minibot speed. Anybody know how much the motors and battery weigh?

Re: under 2 sec Mini bot

Two seconds up the pole is definitely feasible. :D

Two seconds, from breaking the plane to hitting the trigger, that's the challenge.

Re: under 2 sec Mini bot

Make the weight work for you so increases traction

Re: under 2 sec Mini bot

I expect that if you're using any tetrix parts besides the bare motors, wheels, and battery, you're not building the fastest minibot you could :)

I wouldn't be surprised to find out that if you are using the Tetrix wheels you are not building the fastest minibot you could.

Re: under 2 sec Mini bot

You're probably right. Sheet aluminum or polycarbonate and latex tubing is looking pretty good.
