The motors come with a pre-attached gearbox. Did you take that off?

[MP3341]

theguyz, perhaps you want to reduce the weight and not use wheels

[TheGuyz]

I think they did take off the gearboxes because when I saw the motors they didnt have any on them. we reduced the weight of the minibot to around 5-6lbs

[MP3341]

hmmm, trim the weight if you want a faster minibot, but if it works and remain consistent, its still competitive.

[TheGuyz]

Ok thanks for all the advice

[TheGuyz]

Umm...what kind of magnets can we use?

[EricH]

I would suggest magnetic ones.

There aren't any restrictions on types of magnet in <R92>. As such, any type is fair game--just use caution if it's mounted on something; whatever it's mounted on also needs to be legal.

[MP3341]

neodymium magnets

And deployment, use 1 movement. In week 1 lots of mini-bots hit a snag after there 1st deployment motion (i.e. mechanism flips down mini-bot shot forward then UP, the mini-bot would not shoot out) in conclusion Less moving parts=the better, and less room for error =)

Team 3680 is having a similar problem with those "latex rod" minibots.

We constructed a minibot with 1/2" OD aluminum rods, attached surgical tubing on them, but the minibot does not seem to want to climb the pole. The rods just run at the base of the pole with no effect.

We were looking into traction issues- do the rods have to have a very snug/tight fit around the pole?

[Chris is me]

Your rods are far too big and as a result you're stalling your motors (they do not have the torque necessary to lift the robot). Try smaller.

Your problem isn't caused by this (probably not a tight enough fit) but I thought I'd mention it.

Lighter is faster as we found out. If you look at Waves, it's very light and it has NO WHEELS! It just has rubber tubes on shafts to drive it up.

A few questions...
How fast? Any problems with amount of cantilever you had on shafts? Is the blue tubing some kind of fatter surgical tubing?
