Air in tires adding to weight?

[Bob Steele]

#1 statement above is excellent... thinner lexan... 1/2 the thickness 1/2 the weight.

think about using rivets instead of screws and nuts... You would be surprised at how much weight you can save...

Of course you need to consider what strength you need and in areas where this is critical, rivets may not be a good choice as a direct replacement.

I would hazard a guess to say that EVERYTHING on your robot weights more than its own volume of air. If not it would float...in air.....

buoyant force...

of course this year is the first year we have to add weight to our robot .... low and to the front

The inflation of the tires is similar to the electrons of an atom, they are important, but weigh nothing (sort of). It shouldn't be a problem and if it is I am sure you can have other ways of saving weight. Good luck though, hope you do well!

If there is more than one scale and you're barely overweight, switch to the other scale and try weighing your robot. At the nationals in 2010, we were half a pound overweight on one scale and two-tenths underweight on the scale right next to it.

Have you tried dumping the code from the CRIO? The bits don't weigh a lot, but they add up.

Your Lead Robot Inspector will determine if you need to lose weight and how best to do it. Letting the air out of tires is not even on their list of 'try this'. I can tell you that many teams have tried this method while at the scale and there was no movement between before and after. However, one of the best ever over weight stories involved four full rolls of gaffers tape that the team had used to raise the wheels. The tape stuck to the bottom of the robot when they came for final weigh in making the robot several pounds over without an LRI foot on the scale.

I knew it! It's a conspiracy!

Just drill a few holes in your tires that should do the trick.
