How much does your robot weigh?

Last year it was definitely easier, but not as easy as this year. The reason this year got even easier is because the robot needs to have a lot of open space if you want to store the ball.

Besides climbers, floor pickups could also get pretty heavy. Not so much because of the pickup mechanism, but all of the work to get those frisbees to your shooter. I believe that 118 was on the edge even after they removed the climber, and they were under 30in tall.

Adding weight's never been a problem for our team. On bag day, (with the one exception being 2011) the robot has always been 110+, and generally we have to put the robot on the Subway diet during our unlock period.

This year looks to be no different, as the robot's project weight is nearing 115.

That's cool though; extra pushing help never hurt anyone.

Our robot is just a shade over 93 lbs as of now. The frame perimeter rules, as well as the KISS principle have led to a light robot this year. Also don't see the need to add ballast (at least in our situation). It's relieving to not have to worry about drilling holes in all our quarter inch plates this year

We were right under the 120 lb (118.5 ish?) mark last year and we didn't have a 20 or 30 point climber.

Practice robot, about 125
Competition robot, about 45
When we get on the field at our first competition, I expect the competition robot to be somewhere between 150 and 154 fully-loaded.

So:

• How much does your bot weigh?
• Are you planning on adding weight to reach the max 120lbs?

We weighed our robot twice so far once two weeks ago, with everything that we thought was going to go on it and we were at about 89LB then we weighed it again on Saturday with everything on it and we were at 97Lb. after we took it off the scale we found out that the battery was in the robot the whole time therefore assuming the battery weighed 15 pounds we estimated the weight to be 82LB, so somewhere along the two week path we lost some weight after we established we have lots of weight too spare we decided to make a few more mechanism for a robot to take up some of that weight, my motto is your given the 120 pounds, you might as well keep adding helpful mechanism until your out of mechanism our weight

I know we plan to add mass to adjust the dynamics of our launch system. This is going to also be the year of how close can we get the CG to the floor!

I agree that it would be more informative if the "91-120" range were broken down a bit. This is the first year in ages (maybe ever) that we have not been struggling to keep under 120- so far we're at about 97 lbs. "soaking wet" (no, no, not REALLY soaking wet, though it HAS been raining here for about forever... and our shop is a bit damp since it really has no walls on two sides...) To me, that is a HUGE difference, but I still have to report in the top category.

Anyway, it's really nice to not have to stress about weight every time we discover that we need to add something!

Also, really nice that we actually have a "live" robot more than 10 days before SBD. That IS a good feeling.

The other day we did weight check and came in at 98 lbs (weakling?) with some projection for components not on the robot yet.
This along with the new 45 lb. (thanks Frank) with-holding allowance told us we could try to develop another sub-system - but that is not our priority in the next week -

and I believe we would add ballast to get up to 115+ lbs.

Question for Adam (and the other <30 lb response) - 30 lbs is your current weight - is it really what you expect to bag?
That would raise definite curiosity about your game strategy...

As of today, ~62 pounds at full inspection weight. We're trying to see what we can remove to keep out for Bag & Tag.

Wait... For reals?

Yeah, for reals. Our 191 pound mentor stood on a scale while holding the robot and the total weight came out to 153 pounds.

Edit: Just to clarify, we want to see what part of the robot to leave in the bag so the rest will be under 45 pounds. Basically, the 17 most refined pounds of the robot.
