I wouldn't be surprised to see some of the faster mini-bots using tetrix metal as well. The few pieces I played with were extremely light.

Re: under 2 sec Mini bot

The real race will be deployment.

Can you deploy faster than 1 second?

Q.E.D.

(unless you are including the start of deployment as well?)
I'm pretty sure that minibot didn't have a battery pack onboard

Re: under 2 sec Mini bot

Our team has protoyped two minibots with good results, and I still think we are far behind. A reliable, fast, rugged deployment method is challenging. Do not underestimate it.

I second all the comments regarding using the required masses to improve wheel traction.

Our team will probably not be disguising our minibot in any way. Right now, it just kind of "feels wrong."

If you have enough man-hours to devote to it, a sub-2-second climb is doable. We do not have enough man-hours.

Re: under 2 sec Mini bot

I hear one FRC team in Phoenix is getting a whole other ex-FRC team (now FTC team) to develop their minibot. Yeah, it can take a lot of engineering effort to make an outstanding performer.

So far we've gotten the bot up in 10 seconds, but we're running into difficulties for making it go faster with our tetrix wheel (not the best traction), and messing around with the gear ratios, and just finding where to distribute weight.
What kinds of designs are you guys using?
ditch the gearheads.

Re: under 2 sec Mini bot

Under 2 seconds, huh? I'll bet that if we see some under 2-second MINIBOTs, we'll also see some batteries that are overcharged and leaking by the end of competitions.

it's an essential piece of equipment for Airsoft. it saves you from destroying your batteries. i suggest you grab one of you are worried about overcharging

Re: under 2 sec Mini bot

Jesse isn't worried about overcharging per se.

They're saying that to achieve sub-two second climbs, those minibots will be depending on an overcharged battery (to squeeze that extra little bit of performance from) to do so, and thus by the end of competitions, they'll be damaged.

I believe the chargers we got for the FTC batteries are almost identical to this (without the branding/different color)

I just ran it without the gearbox and no load: @12v 7700 RPM, @14v 9100RPM. I'm not sure about the available torque.
