Weights on the minibot

Are we allowed to put weights on the minibot in order to balance it out?

Re: Weights on the minibot

I'd assume so. Counting on they are made out of the allowed materials.

Re: Weights on the minibot

Just curious, how much does your minibot weigh?

Re: Weights on the minibot

What in the allowed parts list would be substantially heavy besides the battery?

Re: Weights on the minibot

First, I would strongly recommend balancing your weight using the weight (motors and battery) you already have...

Our minibot only uses magnets to secure itself onto the pole, so when the weight was initially off to one side we trimmed down the aluminum plate on the heavy side and moved the magnet mounts closer to the heavy side. We ended up with the motors about 1.5" away from the magnets and the battery .5" away on the other side, leaving us well balanced and capable of climbing straight up the pole!

It's best to remove or adjust weight to move CG where you want it... particularly since the minibot is a race! If you really can't adjust your design, then perhaps a small PVC tube filled with steel fasteners can help you out.

Best of luck!

Re: Weights on the minibot

It says in 4.3.14 <92> That you could use a NXT brick. Last time I checked they were kinda heavy. You could also use raw material listed in the parts list.

Re: Weights on the minibot

Why would you ever want to add weight to your minibot? That would make it slower. The idea is to make it as fast as possible.

Battery, motors (gearheads removed), some sort of custom rollers, switches, maybe some magnets, and a stick to hold it all together. For the minibot, Minimal=win.

Re: Weights on the minibot

Ours weighs about 2.3 lbs, that's as light as we cold make it.

Re: Weights on the minibot

Don't fix your minibot by adding weight. Move the battery.

You CAN add weight using legal materials, but it will not help your minibot time.
