Shooting Vs. Time hanging 30

FIRST General Forum
#81

Our analysis on kickoff was:

A 30-second climb with 20 point dump is acceptable.
A 20-second climb with 20 point dump is good.
A 10-second climb with 20 point dump is great.

A 30-second climb with no dump is okay-ish.
A 20-second climb with no dump is acceptable.
A 10-second climb with no dump is good.

As a great hanger in 2010, it didn’t occur to us until reading CD later that other people wouldn’t be clambering for a climb. Our specific capabilities lend themselves more to climbing than autonomous programming – something we’re working on, of course, because we always want to be better than we are – so as far as priorities we are tending in that direction even though skill-independent strategy leans us the other way.

I would be surprised if there is reliable 30 point climber all season long that is not at least a regional semifinalist. At most regionals such a robot is probably at least a finalist. Sames goes for a reliable 30 second climb with a frisbee dump, except you shift it up to regional finalist and winner. In my opinion that puts them far above “okay-ish” and “acceptable”.

Consider how big of a swing a minibot was in 2011, and then realize that it takes 2 teleop scores in 2013 to equal 1 in 2011. (I realize shooting discs & placing tubes are not equally as hard, but the average alliance shot 2 balls in the middle goal in 2012…)](http://twentyfour.ewcp.org/post/39402342932/rebound-fumble-aim-low)

As always, I would love to be wrong. :o

You may be right. We climbed with no issues (beyond a slipping set screw, from which we’ve learned our lesson) in 2010–indeed our 2013 lift isn’t a whole lot different than our 2010 lifter… So in that sense I look at it and say, “gee, that’s hard, but not so hard–and once you’ve got it, you’re nails.”

Part of me thinks that every regional will have a dozen or more robots that 30+20 climb, and part of me feels that one or two robots at most will do so, and despite our confidence we’re not going to be one of them…

I’m having a hard time picking apart this game. I know how it should be played, but how it will be played still eludes me.

Woah, hold on there! How do you climb without any moving parts? Lifting yourself off the ground requires doing work, which necessitates moving parts… (unless you use straight kinetic energy, but then you have to stay above the ground for 5 seconds before it is scored)

that’s fantastic!

If teams are concerned about disc warping, I quickly learned this year that it will be almost a non-issue.



I made this assumption on another thread and was quickly corrected. After receiving several replies, I do not believe that this will be an issue…

I think that a 30 pt hang is completely worth it if it can be accomplished. Teams just need to consider what they can do. The bottom line in all robot designs is that the best designs are the ones that work. I’m guessing, based off of Rebound Fumble, that if a team just developed a dumper and 10 point hanger that works reliably every time, they could win a fair amount of qualifying matches and be picked for elims at most regionals.

Don’t take anyone’s word for it. Take some of your own discs, put them through your prototype shooter at max speed with the exit pointed straight at a wall that’s only a few feet away. Take some of of your other discs and drive last year’s robot over them, bot right-side-up and up-side-down. Then make your own decision as to whether or not the dsics can warp. Then perhaps listen to CD about probabilities of occurance (or run the simulation to figure out how often things happen – either way).

Many CDenizens have a bad habit of conjectures that are only based in thought. Don’t change your mind solely on account of them.
