Re: 30pt climb under 15 seconds
 

I think a shooter + 30pt climber will be rare. But, I could be wrong. I am hoping to see it. FRC teams can do amazing things.

Re: 30pt climb under 15 seconds
 

Ya why assume this? There is a good chance that some teams found a way to get a good shooter while still getting a 30 point hang ;)

Re: 30pt climb under 15 seconds
 

I'm just going by the average bot. I'm counting out 67, 1114, 254, etc. (just have to eliminate outliers) We all know they are going to have climbers and shoot. The average bot will either shoot poorly and get the 30 point hang, or shoot well and get the 10 point hang.

(and I'm sure Team Titanium is going to have an insane climber, and a great shooter. You guys always put out a kick-a** robot, but always seem to go under the radar.)

Re: 30pt climb under 15 seconds
 

A random 30-pt climber probably can't do the same autonomous points that the 10-pt climber which specializes in autonomous can. Probably. The robot geometry constraints & height of the low rung make this difficult (IMO).

Now, if it's a NASA team we're talking about ... all bets are off. If it's a team who had great success in previous years at doing all aspects of the game, then it's worthy of a raised eyebrow. Yet until we see 'bots in action, it's 'probably' a safe assumption for most robots who do a 30-pt climb that they can't also do a 7-disc autonomous.

Re: 30pt climb under 15 seconds
 

We decided that it would be better for us to focus on a great shooter and feeder first which we not have done. we left room for a floor intake(being proto typed) and climbing mechanism. i guess we are looking at things too much of a 1 V 1 robot match. It will be great to have two bots that can climb 30 and do auto and then one robot that has an amazing shooter, good auto(3-7 disk), 12-16 disk in teleop in 3pt goal, and a quick 10-20 pt climb (under 5 seconds). Now that is a great alliance. Granted there will be a few that all can climb 30 in under 10 seconds and shoot like crazy.

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

Re: 30pt climb under 15 seconds
 

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.

Re: 30pt climb under 15 seconds
 

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...

Re: 30pt climb under 15 seconds
 

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.

Re: 30pt climb under 15 seconds
 

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.

Re: 30pt climb under 15 seconds
 

That's a lot of air! It'll be impressive to see at the very least.

We entertained the idea of a climbing-only 50-point robot that did everything with stored elastic energy. It's well doable given the design constraints, but we want to be able to shoot, too...

Re: 30pt climb under 15 seconds
 

It will be impressive if it works and spectacular if it fails :) As for the air volume, we are very lucky that one of our engineer mentors has done a great deal with hydraulics and pneumatics and was able to help us out. The math is really quite simple in the end and based on how it worked we ordered cylinders we felt would be adequate. The good news is that we were able to test them on Saturday and they match the math quite well so there is a pretty high degree of confidence on that part of it.

One thing to note. The new tiny compressor gets VERY hot and we blew an air line on the high-side (120 PSI) due to the hot air softening the tube. Pretty loud POP when it's 18" from your head. We also had another line blow out of the little quick disconnect fitting unexpectedly due to it being warm and a little bit of wiggling. This has made us gear the design in such a way as to reduce the amount of tubing as much as possible. Anyone interested in pneumatics should look at McMaster-Carr, they have some very nice fittings rated high enough for what we are doing that will also reduce the number of parts needed.

Re: 30pt climb under 15 seconds
 

How much room will your climber take? Does it still leave you room for a good shooter, feeder and/or ground pick up?

Re: 30pt climb under 15 seconds
 

Hand feeder, yes. Good shooter, kinda - a shooter that meets our needs, yes. Ground pick up, that was never a requirement for us.
