under 2 sec Mini bot

[nuggetsyl]

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

[thefro526]

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?

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

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).

ditch the gearheads.

Our minibot is just over 2 seconds, with battery. We are using the tetrix wheels, but they've been modified (in a legal way). From what I've heard, we're still working on the CAD of the deployment mechanism.

Our minibot climbs the pole in 2.14sec (at least thats what we were told by a comment) and it is built solely from the TETRIX kit's parts.
i'm pretty sure that with a bit improvement or Weight reduction we will be able to go up in less than 2 sec.

Our minibot's first test run-

Here's a 1.8 second run:

Very nice minibot and deployment mechanism. Great use of springs. Very simplistic. With the minibot and it's deployment this year I believe that the designs that are simpler will be more effective. Great work!

I would assume some of these minibots don't have gearboxes.

Or modified gearboxes

[fox46]

Cybergnomes have just done it! 1.88 sec! With room for improvement!

Nice job! I'm assuming you will modify you're deployment to 18 inches.

[Chris27]

Yes.

Q.E.D.

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