Under or over weight?

[Jeff Pahl]

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!

Time to put the lounge seat back on so the freshmen can ride around on the robot...

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 just weighed or robot tonight and we are at 100 lbs. With the extra weight, we're planning to make a simple mechanism to knock down the hanging tetra

[KTorak]

We're about 5 pounds over...and we keep adding to our robot....the rest of the buiild team was replacing steel setcollars with alluminum ones when I left today

[Dested]

Hahaha speed holes. Were at about 110 with battery, so we should be...okay....

[Billfred]

We were seriously over, but with a few switched parts we should be alright.

We were 8.5 lb over. We are now about 1 lb under. 10 lb of weight lost almost entirely with holes.

[Matt Attallah]

-25 lbs overweight...

We have plans to use that 'free' weight also...

OR that -25 lbs can be sent to the hightest bidder....
