This season has been a little hectic (to understate things) in terms of weather. As such, I'm sure a lot of teams out there are splitting up things and taking advantage of the increased weight limit of prefabs you can bring to a match.

What's your team doing?

We're bagging our electronics board and keeping our entire mechanical robot, which weighs ~42 pounds.

Woah. I would never have thought of that.:yikes:

It isn't clear to me, but do we have to bag and tag the bumpers or do we get to withhold them ?

Bumpers do not need to be bagged.

Bumpers are exempt from bagging and the 45lb withholding allowance per R18.

Bumpers don't have to go in the bag.

This should answer that question

Items exempt from this limit are:

the OPERATOR CONSOLE,
BUMPERS, and
any ROBOT battery assemblies (as described in R5-A).

For the first time ever we are bagging a complete and hopefully after getting the programming dialed in today, a fully functioning robot for the first time ever!

Don't forget that any modified spare parts or backups is also included in that 45 pounds.

a 42 pound robot is going to get pushed around quite a bit...

We have a 4 wheel independent swerve drive. We made 4 modules so far and the other 2 back ups will be made in the next week or so. we have a pickup and a shooter currently being made, and we are also bolting on the electronics (not behind at all). our swerve weighs about 7 lbs and 13 ounces fully assembled, and we have an insanely rigid frame. we think we will get everything in the bag this year, and if we don't our robot is on a sub module system. but you will will not see all the swerves in the bag, as we will be playing with them until the mod periods.
Good luck with whatever your bagging first teams!

Too be fair, they also have their electronic board...
So a total of 45 pounds :p

Electronics board, battery, and some COTS weights we'll add for ballast at the competition.

What's a ballast used for? I've heard the word when talking about trebuchets, is that what it's used for.

It's just used to weigh down our robot and keep our COG low. Ballast is basically just dead weight. A ballista, on the other hand, is a giant crossbow mounted on a turret. Pretty large difference. :D

Oh, I see, then I know a lot about those.

*cough* 50 pound bag of chain last year *cough cough*

Bagging and tagging a running/driving 6 CIM base with rotating assembly.

45 lb withold is the 270 degree rotating turret that mounts on top, so that we can mount it on the second running/driving 4 CIM base with rotating assembly for practice.

Turret comes off with 4 bolts. (plus 1 air line and 4 solenoids worth of PWMs), and is installed in the same way.

noun
noun: ballast; plural noun: ballasts

1.
heavy material, such as gravel, sand, iron, or lead, placed low in a vessel to improve its stability.

Or potentially, in this case, to improve traction.

Note in FRC if you are using lead as a ballast it must be encapsulated and at no time should you shave, cut, drill, grind or intentionally do anything that could create lead particles or dust. It also can not be an additional battery even if it is not electrically connected to the robot.

Bagging ... basically everything, maybe even the bumpers. Everything's working, and the subsystems don't really separate well.

Were tweaking and fixing things with our robot today and were gonna be bagging and tagging a completed robot for the first time ever tomorrow. We are a rookie team so this is our first year having a completed robot to enter for competition.

We're bagging the drivetrain but keeping the board, shooter, and pickup, along with pneumatic parts associated with that. Our pneumatics aren't controllable yet

The whole shabang is getting bagged and crated the old fashioned way tonight. Ships out to Texas tomorrow afternoon. Good luck to everyone especially if you lost more than a week like 422 did.

I feel kind of bad as a team taking advantage of the 45 pound extention limit, since here in California we don't get anything near snow...
But only kind of bad. :p

Bagging the KOP drivetrain with 6 CIM gearboxes, electronics, and some frame attached.
Withholding both our manipulators, if we can get that and a frame under 45 pounds combined we'll bring that and replace the bagged frame pieces since its rather heavy and messy.

Is it standard practice to detach CIMs and PG gearboxes from withheld parts and reattach them at the competition? Our motors have not been modified mechanically but the leads are crimped.

We just bagged our drive base (6 CIM, Pnuematics) w/out bumpers. We're hoping to finish and perfect <45 pounds of shooter and loader.

We bagged a functional robot.




...without our entire arm assembly (which currently weighs around 30 lbs).

We bagged and sealed really early for a change @ 7:45 PM last night, a fully tested complete and ready working competition robot (less 2 P.U. arms that weigh less than 2-3 lbs total -each are 3 simple bolt connected, removed so we can make multiple B.U.'s of them as replacements as anything in the max. 20" extension area will be a "defenders target" this year for sure). And of course, we did not bag the bumpers, batteries and operator console.

We lost no actual days to snow/ice or other extreme weather like many other teams of the U.S.. (Feel bad for those that have, but the 15lb. increase in hold out should help some after reading here a lot).

Actually, all we did tonight is blow out the robot(s) well w/ compressed air, pull off those 2 minor pcs, and (eat pizza & ice cream w/ the team), take team pics w/ their new toy, then bagged & tagged & stowed away from prying eyes. (It was pretty slow & relaxed compared to previous years for sure).

What a welcomed change from the last few years! Thanks to the GDC and some great robot designers, and a ton of help from pretty much the entire team over the last six weeks!

Save for 1 ordered gearbox coming from AM soon, and an hr. to install it and 2motors, to make it match the comp bot exactly...Our 3rd. gearbox and motor iteration change for the P.U. design BTW, and finally one that worked well enough to actually trust to get the job done repeatedly)....The practice bot will be ready to hit the field next. (But first,....a few days off for all are in order...The announcement was made tonight....The (OUR), shop is closed until Sunday team! So REST UP after getting that homework done;-).

WHAT!!!! You say I get to actually watch both the Duals from Daytona on Thursday night, and the NASCAR Daytona 500 on Sunday? Wow! Now there my friends, is a FIRST!:rolleyes:

Bagged the whole robot! We have been testing code for 5 days now, its been up and down, but tonight it finally seemed to be working right (including auton)! We are very happy with it.

But, as always, there's a few modifications we would like to make. ;)

We were extremely successful this year in getting a complete functional robot bagged after verifying a reliable two ball autonomous.

We pulled off the wheels (Colson performance which have a long lead time to order) so we could use them on our practice bot.

We then held back a 3D printed box with an Arduino that manages our distance sensor and some LEDs so we could fix a power problem.

We have a pretty good catch system prototype that may get integrated if we can get it to work reliably on the practice bot. There is a lot of debate among mentors and students about the end value of catch. The nice thing is that our robot is modular enough the whole thing can be put on or taken off is less than 20 minutes.
