What did your robot sacrifice for First Frenzy?

[Solace]

we originally had a bot that could do everything, but we had to sacrifice the ability to get on the platform because of weight issues. we can still hang from the carpet though, so i hope it won't hurt us too badly.

You can never make your robot into a 'swiss army knife' (essentially a robot that does everything). Yes, it may be able to do certain (or all) things, but it will not be proficient at any of these tasks, which is why you must have a primary task that you want your robot to be exemplarily phenomenal. So every year, you should focus your robot to do one thing and that thing extremely well. So as a team, you guys (as an example) have to decide if you want to be the best ball-herding robot, or the best bar-hanging robot, and what is the team going to do to make that idea, that dream, a reality.

In other words, our team sacrificed a lot in order to be the best at what we believe we do well.

Let's see...

Last year we sacrificed driving for ... well, just sitting there and not driving. Turns out that wasn't such a good idea! So this year we decided not to do that again.

We willingly sacrificed treads for wheels (yeah!!!).

We willingly sacrificed sleep to finish the robot (almost - the day isn't over yet)...

We willingly sacrificed our sanity to allow several members of the team to stay on...

We willingly sacrificed our home lives, free time with our families, several assignments at work, grades at school, personal hygene, tools from our shop, money from our pockets, any semblance of a nutritious diet, all forms of an ordered lifestyle, and endless hours in the robot shop, all to build a team that quickly became "family"...

and finally - I willingly sacrificed my humility and self-respect for a box of Krispy Kreme donuts.

Dave,

I think this might be the time to bring back your description of Krispy Kreme donuts for all the new members of the CD Family.

PS. Any chance of seeing you in Phoenix for the Reginal?

With only 6 weeks for the Design/Build/Test, you can do it all, just not well.

Given enough time you can
1. Drive extremely well.
2. Manipulate objects extremely well.
3. Climb extremely well.
4. Lift/Hoist extremely well.

I think the secret is to, decide what you want to do,
Design a solution "that meets the needs" (not exceeds)
Build it
Test it
Fine tune it for performance when you have time.

If you weant to do it all the "extremely well's" will by default drop to "just meets, but does the job"

Just my 2 cents.

We willingly sacrificed climbing onto the platform, but we should still be able to hang from the carpet.

As for doing everything, it is usually impossible. The key is to identify the tasks that aren't worth the effort to design a mechanism for. For example, stacking in 2003 and picking up the small balls that were on the field in 2001.

[pras870]

Herding, that's basically the only thing my team sacrificed. We figured it wouldn't be a deciding factor, and from the looks of the scrimages, it doesn't seem to be. It's the year of the hanging it looks like, and luckily we it with ease. Just my 2 cents.

[IronSlayTallica]

We sacrificed sleep and a lot of our time in the preseason. We took a risk and laid out/built our drive train before the kickoff. That's why we're not stressed now and happily packed it into it's brand new, pretty painted crate tonight. We actually spent a lot of time on... i guess it would be... public appeal. It's quite shiny and our cart matches our crate which has hand painted detailed flames. We really haven't had much to do except having everybody drive at least once, messing with different programming (Making it more efficient to switch) and making it, as I say, pretty! This is the first year we're not stressed with weight. We're actually a tad under.

[pras870]

Yes, it's shiny because I wound up polishing/compounding almost every main part on our bot this year on what seemed like a weekly basis. It's always satisfying when you come back covered in compound after a hard long night.

[Tom Bottiglieri]

we couldnt decide what we wanted to sacrifice.. so we made all different stuff to do everything, and we're gonna decide what looks best at regionals.. (8 arms in the crate baby)

[Aignam]

Everyone on our team is worried about our seemingly high center of gravity. It's been a long time since we build a robot with a high center of gravity (not since 2000, but we all know how that worked out..) and we're generally worried about tipping. Theoretically, if our arm is in the closed position during a fall, we should be able to push ourselves back up and keep on driving. We'll see.

[Ryan Albright]

the only thing we sacrificed is herding balls well the front of our robot will do it but we dont have a specific thing for it. we didnt sacrfice anythign on ground clearance our robot sits lower then any other of our past year robots 1' in of the ground but we can still get up the 6 in step

[IronSlayTallica]

To clarify...

We didn't actually build it. No metal working was done. No machining, nothing. We thought about it, drew plans, etc. No actual building. Slip of the fingers. Sorry if that came out differently than it really was.

[galewind]

We Sacrified too much time developing and agreeing on a strategy, which, in the end, we weren't able to accomplish due to too much time spent developing and agreeing on a strategy.
....

sooooo.... due to weight we changed the manipulator designs at the last minute. Our drive system, electronics (with battery), and frame weigh a combined 97 pounds (without skins). Our old manipulator weighed 31 pounds, deweighted, and it was not in complete working order. We COULD have put it on, but it would have been very difficult and time-consuming to remove weight from the rest of the robot.

So we went with something more simple that seems to be good to go, but we didn't get any practice time with it. We do know we can grab and hang, though, and get rid of 2x balls... oh, and we're annoyingly fast and versatile on the field. heh, we find that climbing the 6" platform is significantly easier than taking the stairs.

[Jonathan M.]

Well.. At first we decided to sacrifice hanging. However the chasis was still made to be able to climb the platform. We spent the majority of the 6 weeks building and designing the 2x ball handler. In the end, the night before our scrimmage we added the hook that was designed a week prior, and tested the hook out at the scrimmage. So it would turn out that the hook worked better then the 2x ball handler! Since then we replaced our "gripping tongs" with different grippers that work better. So I'm not sured what we sacrificed all together, we can do pracitly everything on the field, but what we do best is hanging. And the one thing we concentrated on the most is 2x ball handler.
