from inventor..

aluminum = 0.098 ( lbmass/( in^3 ) )
lexan = 0.043 ( lbmass/( in^3 ) )

it was just an example.. not an actual scenario. i would use 1/4 aluminum and get it anodized cuz it looks uber-cool

no no no, the trick is a well known trick among veteran teams. Its offical FIRST terminology is "Speed Holes". These are the mysterious large 1 to 2 inch holes you'll see scattered about a robot, usually made while standing next to the scale using a large hole saw. Our old engineer leader used to get a little speed hole happy with the drill, he's no longer allowed near a drill. Heh.

Why not a vacuume?
Just evacuate your entire robot. Its less dense then helium or hydrogen.

Or better yet, why not raise the pressure in the building where the regionals are at. That way, if your frame is sealed, the air in your robot is less dense then the air in the stadium.

When you weigh, be sure to use a dead battery (remember electrons have mass)

If you're really adventurous, you could short the terminals on your battery and boil off some electrolyte.

Also, try to cut some weight out of the RC, works every time.

In addition be sure to sabatoge the scale. When the scale is zeroed, put somthing heavy on it, like a battery. Then the scale is "zeroed" at about 13.5 lbs.

Oh by the way, don't actually do any of this stuff, its not GP

Good luck yall!

Make sure your code has as many 0's as possible...Everybody knows that 0's are lighter than 1's

No, no, no! The weight of binary values goes against intuition here. Since the beginning of computer storage, 1's have been represented by holes in paper tape or punched cards, making them lighter than 0's. This has carried through to electronic memory, where a logical 1 is customarily represented by a higher positive voltage, meaning fewer electrons.

Actually, if you did a vaccuum, you wouldn't get the upward force of helium (and other) gases. I can have a balloon filled with helium fly up, but a balloon with nothing at all in it just kinda sits there .

Of course, the amount of helium in your average balloon lifts a couple of grams, so you'll need a bit more than would fit on a robot to make any difference...
