30pt climb under 15 seconds

[RonnieS]

Everyone is saying how they have developed a 30 point hanging mechanism, but realistically how fast can u actually climb? Please share!

This mech. could do 15 seconds easy if geared right!

But how much space does that take??

Seems like a very small amount, at least, from what I can see.

one minute? we'll see pretty soon.

I guess I'm just not seeing the point in teams going for a 30pt hang, most teams are taking a lot of there robot space for a climbing mechanism when you can make up for a 30pt climb in auto easily by scoring 3-4 disks plus an easy 10pt hang that can be done in less than 3 seconds and take up little space. Thoughts please

Personally, we are planning to dump in low basket, and 30 point hang. We plan to be a straight elimination robot. Yes, their will be teams that score more than we do, but we will be completely out of their way in the elim. matches. They can do their thing and score like a maniac, and we can defend, feed, and hang.
(best thing about being at MSC)

I dunno... 18 to 30 points auto. Plus around 30 in teleop. A quick 10 at the end. That 58 to 70 point shooter beats a 30 to 54 point climber. Maybe I'm just optimistic.

My team is going for the climb based on past experience.

In 2012, we decided to try a shooter, and spent ~4 weeks prototyping our shooter. at competition, for more reasons than one, we ended up being a less than average shooter, and scored most of our points by balancing, and ended up not playing in eliminations. Then, at Cow Town Throw Down, after we had tried to renovate our shooter, we ended up placing nearly dead last, with only 1 win. This influenced our strategy this year. We determined that if we built a shooter than we would be a 'vanilla' robot, and not be playing in elims, just like last year.

So we decided if we could do this one thing, climb, than we could do better than many robots at STL regional and maybe have a chance at playing in eliminations. With new materials and sponsors this year, we think we can do it.

tl:dr: bad previous experience made us re-evaluate our game plan, and determine that a 30pt climb was our best chances at eliminations play.

We learned last year that we shouldn't rule out parts of the game that seemed like they weren't worth going for. It kind of killed us at champs when all the short robots were balancing 3 on a bridge.

We will be doing the 30 point hang and it will be under 10 seconds. We may even bring up 4 of those colored disks at the end for bonus points. There's no turning back now, we're pretty dedicated.

They need to go to feeder everytime, and that is where all the opponents are. I say: 18 points in auto(3 top, average), lets say 12 points in tele. (4 HP frisbees), 10 point hang vs. 6 points in auto, 6 points in tele. (4 HP frisbees), and 30 hang.
40 vs 42
(not counting the 4 Bonus disks)

I think there will be some elite bots that can both shoot and climb for 30, but it will be rare. We are a second year team and have pretty much ruled it out. Not even sure we could climb for 30 as our only goal. That is a big challenge even with the appropriate design, engineering and manufacturing resources. I think that defense is a wild card, but you guys have more experience at this than I. Definitely looking forward to seeing some interesting designs this year.

From a pure work / energy perspective, it should be very feasible.

Tossing out a few rough numbers:

200 lbs * 10 feet * 32 (feet / second^2) / (15 seconds * 12 volts) = 15 amps.

YMMV.

Why assume that a 30-point climber can't do the same points in auto as the 10-point climber?
