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.

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.

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.

Well I guess since Steve said we are going to do it, I guess we have to now...Should be fun!

Our climber design is significantly faster than 15 seconds in it's raw form. In practice, we will likely slow it down to be closer to 15 seconds so it doesn't beat up the robot so much. It also takes up a lot of space on the robot so all our other components need to be well positioned.

Faster than 15 seconds? I can't wait to see this elegant solution in action. Everything my team has brainstormed up we believe will take much more time than that...

It's reasonably elegant but it's not earth shattering by any means. We are using pneumatic cylinders combined with springs and the extension/contraction time of the cylinders is a bit under 1 second each at full weight. We need to articulate a few times to travel up the full pyramid and that's that. As the compressor is slow, so we will be storing a ton of air on the robot initially to power the cylinders the entire way. It comes out to something like 6 seconds or so if you just let the cylinders go full speed. Our concern is that at each step the robot will "bounce" and at that speed, it could bounce off. So we will likely slow it down with flow restriction to make sure nothing moves too quickly.

Would you be able to share a video? If you dont mind me asking.

Absolutely once it's machined and working on the actual pyramid in it's final form. It might all fail once the robot is all put together too Likely a week and a half or so away at our current rate before we publish anything huge. I bet we could show a lot of photos this weekend though.
