under 2 sec Mini bot

I am starting to think is possible to get a mini bot up in under 2 secs.

Re: under 2 sec Mini bot

I think it's been proven that a mini-bot can climb the pole in less than two seconds.

I wonder how many people can figure out how to do it?

Re: under 2 sec Mini bot

Today while at work I was doing some math on my phone and I got the theoretical time very nearly below 1 second.

Re: under 2 sec Mini bot

How are you getting your minibots to do that?
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?

I won't tell you exactly how. But, concerning weight distribution ideally your weight is pushing your drive wheel(s) into the pole, concerning gear ratios find the top of the power curve and eliminate extra gearing as each stage adds inefficiency, concerning tetrix wheel traction slit some surgical tubing down the middle and put it around the wheel with PVC glue to secure it (just an idea, haven’t tried it).

Good Luck

Re: under 2 sec Mini bot

It's all in the design.

1. Minimize weight.
2. Increase efficiency (eliminate gears)
3. Maximize power through gear ratio and wheel size choice.
4. Profit!

There are also some other games you can play to increase the power of the system (legally).

Remember that that video is without a battery. Is there any minibot who has actually climbed the 8 ft with a battery in less than 2 seconds?

Re: under 2 sec Mini bot

Those of us who can/have done it aren't likely to show anything until competition, otherwise everyone will be doing it. Even then keeping them covered in the pit might be common. It's so easy to reconfigure these tetrix kits.

I agree. Has anyone considered having a 3 second bot for Thursday and Friday, and saving the sub-2 second bot for Saturday as a secret weapon?

That is interesting. But even then, if it uses the same tetrix parts, and if another team has the parts needed, I think they could create it over lunch or something. I think it is a good idea to keep your design concealed, but you can keep it concealed even when you are using it in competition.

I would say this is a bad plan since you are doing an unnecessary limit. Do not purposely weaken your team's capability to effectively complete the challenge. Do your best at qualifications so you can use the "secret weapon" during eliminations.

EDIT: after reading Cyperphil's post, if you want to really hide then cover the minibot with polycarbonate since its allowed.

Re: under 2 sec Mini bot

Wait a minute here... So teams have already build (or at least prototyped) their minibots already? Our team only has the CAD and a prototype made with servos. We are behind.

edit: our design is so crazy that I doubt that any team can fabricate the deployment system and the minibot in the 2 day period.

My team started prototyping the day we got the FTC kit. We went through I think at least 4-5 different prototypes already. Forgot if our current minibot is going to be final design.
