Hmm....

I imagine for a 1:1 (pre mod) reduction it's more efficient to leave the gearbox as is than to take out half the stages and compensate for the speed increase with Tetrix gears.

But for a 0.5:1 (pre mod) - that could be interesting.

Wow.

We are 4.5 with a 1 second deployer. We havent tested our other two mini bots yet. 2:1 gear ratio, magnet holding method.

not to show off or anything... but this is our minibot... water bottles attached to simulate battery weight.. 3.4 seconds!

Re: Minibot climb rate
 

nice job.

Re: Minibot climb rate
 

Looks like a nice start!

Re: Minibot climb rate
 

Does anyone know the weight of the individual tetrix parts like the large gear=xlbs, motors=ylbs sort of thing?

Re: Minibot climb rate
 

According to our scale in the shop battery is 1 lb 5.1 oz and motor is 7.0 oz.

Re: Minibot climb rate
 

Answer to this question is in this thread. It would be helpful to read the whole thread.

Re: Minibot climb rate
 

our minibot climb the pole in approximately 2.5 sec , a little less.
with all the wight on it , the battery is attached to the minibot.
you welcome to see it in the post:

hope for comments on it .:)

Re: Minibot climb rate
 

The photo was taken seconds after opening the box for the first time. It was quite clean and lubrication was pretty light.

Re: Minibot climb rate
 

Considering the use of tiny helical gears I think adding more lubrication will help even unmodified gearmotors.

Re: Minibot climb rate
 

I looked at one of the transmissions we had, and I didn't notice any lubrication. It may have been there, but I couldn't see it or really feel it.

Does anyone have a good grease for these guys? I'd imagine you'd want a pretty light grease.

Re: Minibot climb rate
 

Has anyone tried the Thermal-Protected DC Motor Power Cable yet? If my memory is correct it's set for 2.4 amps, which is lower then some of the motor current draw that I've seen people post. I assume it will work for a short time at a current draw of above 2.4 amps, so I'm curious whether it works for other people.

Re: Minibot climb rate
 

We used the tetrix motor cables last night. They worked great, and did not trip to the best of my knowledge. Judging by time, it was pretty close to the peak power point.
