Are You EPICALLY overweight?

FIRST General Forum

Guesshat? We weighed in at the Sussex Mini-Regional, and we somehow lost 10 pounds. I’m not sure how, but now we’re only 20 pounds over. We think we can also lose the CIM motor powering the insanly heavy and high tension belt system. That could be another 5 pounds right there.

Unfortunatly we blew out the fuse on our cRIO while there so ALL we did was get weighed. LOL? Argh.

Seeing all these teams that are significantly underwight doesn’t make me sick, It just means they had much beter planning than our team did.

ya, somehow we keep ending upunderweight the past few years… in 07’ we had soo much extra weight, we had to put a 15 pound steel bar on the back of our robot… last i heard, this years robot was still a bit underweight too…

#65

Mentors last year and this year told you guys to watch weight.
Last year you were 7-8 pounds overweight 3 days before ship.
This year you are 30 pounds overweight 2 days before ship date.
Next year is it going to be 60 pounds overweight 1 day before ship date?

Should of listened to mentors sooner.

You probably mean that you make everything too big and strong, which is kind of the opposite of over engineering it. Engineering means designing, and the art of design is to do the most with the least…so a well engineered robot will be light, simple, inexpensive, easy to build, work well, etc.

It sounds like you didn’t do enough engineering.

(the term “over engineer” is a pet peeve of mine)

We were 5 pounds over weight last night. but we put our robot on the south beach diet drilling some holes all night. every ounce counts :wink:
we ended up losing a couple extra just to know we were safe incase we needed to add some small other things.

i know you guys will all hate us for this but we are 40lbs under:D time to add normal force.

We too are slightly overwieght but we came up with a better plan, we are going to convince the judge that Dean meant 120 lbs on the moon, so 740 on earth, we will let you know how it works.

#71

I think you’ll find that the legal definition of a pound actually describes a mass, not a force. That’s why spring scales, which measure force, often bear the caption “not legal for trade”. Balance scales and calibrated masses are not affected by gravity.

#72

We are 10 underweight

#73

We’ve redesigned our systems are are estimating to be within 1-2 lbs overweight. Then we get out the step drill. :smiley:

Also, the mentors didn’t really plan for weight - no one did. We were just trying to finish the design.

#74

We were 3 pounds over and we’ve been putting cheese holes everywhere we can. We also lost a full pound by removing 3 unused cRIO modules.

#75

1902 finds the word ‘potato’ funny as well.

#76

We’re 25 lbs UNDER weight and we ended up adding 10lb weights to the back of each side.

#77

we ended up modifying our entire ball collection and delivery system, and now the robot weighs 121 pounds lol

upside is the camera now aims our shooter and our harvesting system dosent jam anymore:D

#78

The pound is considered both a measurement of weight, and of mass, therefore, it is slightly ambiguous to the pedantic eye.

However, unless you plan on getting the scale off earth, 1 lb(weight)==1lb(mass)

#79

The scale said 118.9 when it was about ready to go in the crate…I guess we got lucky, because we sure didn’t have a weight budget this year.

We have yet to weigh the robot as a whole, but so far we r about 6 lb under (last time i checked) we still have some stuff to add, therefore, we r looking at hitting weight near perfectly.

#81

make that 3 lb

#82

UPDATE! We lost ~55 pounds and are now 15 pounds under weight! And the bot still works!!
