Under or over weight?

[Zippiot]

i found something yesterday that surprised me...instead of using 1/4 aluminum plate it is 1000 times easier to use 1 inch thick lexan, it is also just as strong and about the same weight (plus its see through!) if i had known this from the start many of our mounts would be lexan, which would actually drop us 10 lbs according to my math. right now without battery and without a few electronics (just the board and speed controls) we are 86 lbs, but we used large wheels and even though the bot is very stable (almost impossible to knock over as i have found out) we are going to add some steel weights to the bottom to bring down our center of gravity. maybe a spinning light display too

we are over.... as usual

[Fixen]

Oh, we have too much weight to spare...our bot's pretty much anorexic.

Our robot still isn't finished in entirety, but we have already been shaving off bits and pieces due to the weight. Our arm takes up 1/3 of our total weight, without any pnuematic pieces added to it! We're in trouble.... or are we...

We'll end up at 119.8, but at least this year it looks like I'll get to put about 20 pounds of lead where I want it to counterbalance the arm.

We weighed in tonight at 113.2 pounds - with the compressor, all the pneumatics stuff that we originally weren't going to include, the new mobility system - and the battery. 100 pounds even without the battery.

And people thought we were kidding when we made this post!

So far, we are underweight. Our chasis, drivetrain, battery, compressor, electrics, etc, weighs in at 83 lbs, or 70 lbs san battery. So far, all of the arm components weigh about 35 lbs.

Last year we found we were 19 lbs overweight a week before ship. The solution, starvation diet. Also, for those of you overweight, 12 AWG is heavy, especially over long runs. Last year we saved ~4-5 pouns by trashing our beautiful neatly laid out electrical system which must have wasted miles of wire. It really is possible to lose weight in the electrical system.

On a side note. We were vastly undereweight rookie year (due to an arm that got chainsawed). Although we were out of town, one of our mentors had a 25 lb bag of steel buckshot in his truck. Buckshot + HVAC zipties == awesome ballast.

We are 90% done and we are 19 lbs under weight, That is the first time in 3 years we have been underweight. All we have to add is some lexan on the sides and a few more 1/4 20 bolts and we are done.

We are underweight so far this year. Reason being our base is a lot lighter than previous years, but I'm glad we aren't the only team considering ADDING weight.

Surprisingly team 1493 is looking pretty good in the weight department. We evaluated all designs in cad for their weight properties, and added known weight components. Once we realized that all of our components would be about 20 lbs overweight, we began having our cad program drill holes in our frame, arm etc... We drilled the holes, and used the light weight materials along the way, as not to have to do that at the end. The bot weighed in happy 5 lbs underweight. Come competition, we will be right at weight after we add our siding boards and cosmetic accessories. Good luck at making weight, as it's not much fun getting to competition and running back and forth from the bot to the scale with handfuls of aluminum chips.

We are in the same boat if the scale is right. The scale looked like a larger/older version of a triple beam balance. We weight 107 and that is also with the compressor which we thought we weren't going to add.

[Captain Rich]

We are under, but because we removed the second set of chips from the drive, I'm drilling holes in hope of getting thoes back on (6 pounds... ulgh)

I hope you aren't having the freshmen on the robot during the matches, since they really don't meet the flowchart at all. Freshmen are great energy sources for cleaning the back room or sorting things out, but not so much for stuff on the field.

I think we are fractionally over currently.

[408Oxidation]

For once, we're 30 pounds underweight. Means we can actually add some counterweight for the arm to get it turning better....
