Was there space for a shifting transmission, what are the reductions / top speeds?

How fast can you climb the pyramid outside a controlled setting?

And most importantly, have you tested to find the limit to your shooter's range? :D
118 is one of the most open teams I have ever encountered at a competition. If you ask them they will invite you into their pit and tell you how they came about each and every part of their robot. I recall them having brochures last year that also detailed every technical aspect.

Might just ask them for a copy of that brochure if you aren't going to run into them in person. (And assuming they put one out this year)

Re: The Robonauts 118 - 2013 Video
 
Now I'm curious as to who would come out on top in a one-on-one between Titanium (1986) and Robonauts (118).
BASED ON REVEAL VIDEOS
(Let's say it's a full court match with all 45 discs each.)

Autonomous: It would appear that Titanium has a stronger autonomous mode, whereas Robonauts did not show off a multi-load autonomous.
Titanium - 42pts
Robonauts - 18pts

Teleoperated: I have to say, Robonauts would take the teleoperated period based off of their ability to fire off full court. Titanium, while bringing a strong, accurate shooter to the table, have not yet shown off an ability to fire full court. In this one on one, Robonauts do not have to worry about heavy defense, so they would be able to fire off all 45 discs for an easy 135 points, and have time to spare to get in place for a climb. Titanium requires a 4 disc cycle, and as stated, they have a 17 second cycle. As they also need some climb time, that affords them 5 cycles, for 60 points.
Titanium - 102pts
Robonauts - 153pts.

End Game: Robonauts might just take the end game, and for one very specific reason. Colored discs. As Titanium climbs on the inside, it would be difficult for them in their current configuration to score the colored discs. Robonauts, however, climb on the outside and would be easily able to "punt" the colored discs in and I would be surprised if they do not. But, as this ability has not been shown yet, I am unable to award them the extra 20 points, *as their shooter faces the wrong direction. Thus, each robot receives 30 points.

Total
Titanium - 132pts
Robonauts - 183ptsu
And thus, Robonauts might actually come out on top IN A ONE-ON-ONE. However, if Titanium is able to reduce their trip time to about 10 seconds, it would be a very different game. As well, if this were match conditions (meaning there are 4 other robots on the field), Robonauts cross-court shots would be greatly reduced and Titanium would come out on top due to their massive point lead through Autonomous.

Just my $.02 and waiting until Week 1 start. Titanium will be at Hub City, Week 1. Robonauts first event is Lone Star, Week 2. Hopefully, Titanium will not be affected by the perils of competing Week 1.

0% chance you will see any long range shooter make over 20 discs in a match and have 100% accuracy. So your assumption is taking some HUGE liberties with the scores.

I agree on the 100% accuracy, I disagree on the more than 20 discs. If left alone 118 could easily make 30-35 discs in an entire match.

Oh no no no, I didnt mean they couldnt make the 20 in a match; I meant that you wont see a team make 20+ in a match while having a 100% accuracy. I full well see teams getting 20+ this year in a single match. Sorry for the confusion in my post.

They may have been able to lightly shoot/punt discs into the pyramid goal from the top if they're shooter was on the same side as they're climber, but as it stands their shooter faces outward when they climb, so I doubt they are able to add these points easily.

Re: The Robonauts 118 - 2013 Video
 
You also fail to mention that 118's 30 point climb seems a lot slower than 1986's. They've got a clocked time at 21 seconds which is the fastest seen in the competition so far (shameless plug: ours has been clocked at 23...but we may be able to trim some built in delay times to make it a tight race ;)) Anyways, until we really see how slow (or fast) 118's climb is, we really can't tell which is theoretically superior to the other. For my money, if I was in the envious position of having to make an alliance selection between those two beautifully engineered machines, I'd take 1986. Full court shooting when you're less than 30 inches tall is going to be moot as soon as you stick a defender in front of you. Once you eliminate that factor, 1986 looks to be the superior machine.

I wouldn't say no to either being on my alliance but, taking away full court shooting and at this current time of only seeing video, I would take 118 over 1986 for the simple reason of how fast 118's floor pickup is. Now that might not matter come Champs when there might not be a ton of discs on the floor.

Also love 2481's robot, can't wait for Wisconsin...

Well, obviously I wouldn't say no to either of them either. That would just be insane. The fact that we're having a legit theoretical debate about this is proof enough that both those teams look to be redonkulously good.

In any case, with the recent rule change, I'm not quite sure how big of a factor floor pickup will be come competition time now. That's the biggest thing I'm going to be looking for with regionals starting this weekend. I could definitely see if an alliance robot was sent back to the feeder station with the role of dumping discs on the groud as close to the goal as possible for floor loaders to feast on, then 118 may have a slight edge in possible points per second scoring rate. I don't know, maybe coupling that trade off with the climb speed of 1986 and it's a legitimately even wash between the two of them. In that case, maybe it comes down to alliance synergy preference. If so, I'll take the faster climb speed so it can remain an active tele-op factor for as long as possible, in whatever role it's performing - offensively or defensively. Based on your comments, it seems like you'd prefer the faster floor pickup...

hmmmm...could that be a possible hint at what Wave's bringing to Wisconsin? ;)

Thanks for the kind words regarding our robot and we're obviously very much looking forward to see what you're bringing to Wisconsin this year, as well. Hopefully, we'll get the chance to share the field this year. It should be a ton of fun! Can't wait!

Best of luck to you guys!

I imagine that in this hypothetical match titanium would just sit and block 118, instead of attempting to score. Full court shooting from that low is pretty easy to stop.
Even in this hypothetical scenario it would still be much closer than you make it out to be. And if I was selecting for a real world alliance 1986 would win out in my books.

You can definitely figure out who to pick first for your alliance from a minute and a half of video of teams showing only their finest moments, all alone, on their practice fields...

Right?

Robonauts are <30", should be really easy to block them for full-court shots.

But someone will have to do it. I'm sure a lot of disorganized alliances will fail to stop them quickly enough.

Re: The Robonauts 118 - 2013 Video
 
When I see the Robonauts unveil video annually, I see one of the best fabricated, engineered robots every season.
We were lucky to have been able to compete, both playing against them and with them during eliminations at Lone Star in 2012.
I could stare at it all day, marveling at how well the machine is built, how beautiful it is, and how cool it is with the LED's, laser cut (water jet) features, etc.
The best part of the video is the choice of music and how its timed with what's being showed in the video. That in itself has inspired many other teams to do the same at their own unveiling.

However, many in this thread are already trying to predict scoring scenarios based on this video clip.
As Cory has mentioned earlier, I dont think any team features too much on missed shots, robots falling (I heard of a few already. :ahh: ), and other mishaps in robot practice and filming.

On another note with regards to full court shooting, shooters are very similar this year.
Its no secret on how to make shooters more reliable, shoot farther, or faster (with PID and other similar programming aids).
The question becomes what is viable for your team and alliance, especially during eliminations.
We have a shooter that can shoot reliably from full court distance and quickly. However, you can bet that we would never do it in a match as our primary means of offense. One missed shot from a load of 4 discs is too low of a percentage, especially with a tall robot right in front of you 60" tall.

What stops a tall robot from defending a short robot at a close distance? Not to mention the inevitable trouble of trekking across the field for each cycle of four shots. Plus the missed shots from full court will save any floor loading robot a considerable amount of time and potential distance traveled as the disks are brought to them, instead of vice versa.

Then again, this is all theory crafting. I expect full court game play to be immensely huge this weekend, regardless of whether the disks end up in the goals right away, or if they're merely being passed from robot to robot.

I am getting a bit off topic though. The only really visible pluses to Team Titanium's bot right now would be their floor-loading autonomous mode, and faster climbing speed. I assume, however, that a team like 118 will soon have a similar monster-auto, and the corner climb frees a lot of space for a potential triple high climb. These two robots are both excellent top picks, with outstanding release videos. They're both a source of inspiration for rookies and power houses alike.

I'm not sure if this is your opinion about 118 vs 1986 in general or a response to my post.
"What stops a tall robot from defending a short robot at a close distance?"
Easy. The Pyramid.

"Not to mention the inevitable trouble of trekking across the field for each cycle of four shots. Plus the missed shots from full court will save any floor loading robot a considerable amount of time and potential distance traveled as the disks are brought to them, instead of vice versa."
This depends on how fast/effective you are on traversing the field. Any shot missed can be picked up by your opponent as well.

"I expect full court game play to be immensely huge this weekend, regardless of whether the disks end up in the goals right away, or if they're merely being passed from robot to robot."
If you had an alliance formed where this was your main strategy, I'll make sure my 60" robot alliance partner is there to greet you.

You dont even need a 60" partner. You just need to bring a 60" wall with you to your regional and strap it to whichever lucky robot you pick 3rd.

Or even better....bring in a pile of raw materials that can be made into a wall. There's a penalty for fabrication.

I think full-court shots are going to be a large factor in qualification matches, but not as significant in eliminations.

And for fun....I'd pick 118 in a heartbeat, and I sure hope they'd pick us. Why do we have to make an either/or choice? :)

Why bring materials at all? Just use the pizza boxes from lunch time to construct a large cardboard wall.

My mechanical design abilities are very limited (computer guy) but I'm going to be very impressed to see a cardboard wall that can stand up to more than a couple of shots from a team like 1806 or 118. I think you'll need something for bracing.

And anyway, wouldn't you get penalized for the bits of cheese that stayed in the field? :D

While I was at LSR I had a chance to see them do some repair on their shooting wheel. From what I saw, All it was was a round piece of foam spray glued onto a disk that was spun by a mini cim. Quite innovative if you ask me..

It is just a foam circle, sure wish we thought of that. It's like THIS sorta stuff.

Edit: That is, a foam circle with round sheet metal on the top and bottom to keep it in the right shape while it's spinning.

They had to take off their 30 point climber due to weight issues.

Partially true.

They also looked at how long it took to climb to 30 and decided that they could score more points by cycling rather than by climbing. Also the falling factor came into play.

After they took their climber off they reinforced other areas of the frame, so if they were to re-attach their climber now, they would have weight issues.

If they add it it would also probably be a completely new design. From what I heard they weren't happy at all with that climber, and believed there was no way for them to make it fast enough to make it worth it. Also, the current design interferes with their more effective cycling HP feed.

Taking the climber off prior to our first regional was 100% not due to weight. It was instead due to the fact that it just wasn't good enough. Good enough for us was a 10-15 second climb. This was the metric we were shooting for during the 6 weeks. When we went into the bag, the climber was at its best 30-45 seconds to line up to the pyramid and climb to the top. After seeing how discs were being scored in the week 1 regionals we decided we could add a simple 10 point hang and score more than the 20 "extra" climb points with discs in those last 45 seconds.

With the climber we were right near 120lbs. Removing it allowed us to "put weight" into other systems and make them better, increasing the overall scoring potential of the robot.

In addition the climbing was always extremely nerve racking and we weren't at the point where we had confidence we wouldn't fall. Taking it off and eliminating the possibility of a tournament ending face plant was a side benefit of our decision.

We kept working on the climber but realized it was never going to meet our speed metric. In addition we'd need to re-lighten mechanisms back to their original config to put it back. We decided the robot would always be better overall without it.

It was a cool climbing method that we spent A LOT of time on. It's too bad it didn't pan out but it was fun to work on and taught us a lot.

Do you at least have some raw footage of your climber? Or do you have any plans to put it back on during the offseason? I would love to see it in action (and not just the edited version in the release video).

Just out of curiousity, what were some of the additional improvements you made?

I believe the biggest one was their hopper. They have a cycling hopper that feeds from the lowest feeder slot instead of the middle. This makes it more reliable and much faster to cycle faster.

How did the extensions near the ground pickup work, the ones used to gather all 7 discs in autonomous? Did it extend out as the match started, or was it always in the extended position? I never got a chance to look at it closely...

They extended out as the match started, I seem to recall.

118 should do an IRI "reveal" video to show their current setup (or perhaps IRI changes).

I'd also love to see some pictures of their climber. I stopped by their pit in St Louis to see their floor pickup, but I've never seen the climber up close.

Their 30pt climber was taken off due to weight issues.

I never got a chance to see this robot in action, in person.
I get 2 consecutive weeks in July and our robot gets to "sit" next to it, in between events.:)

Could anyone explain to me how their hopper worked? Also, if any one has clear photos of it, that would be amazing!

They had an elevator-like hopper. It was lowered when they were loading it, and elevated it up to the shooters height.

ohrly? 29-06-2013 18:53
Do you know how they got Frisbees into the hopper? It seemed like they pushed them in from the bottom, but I couldn't figure out how they make room under the other Frisbees.

Not sure I follow?

The shape of the frisbees was such that if you slide a moderately thin piece of lexan (or similar material) towards the frisbee, the frisbee would sort of hop on for the ride. Combine that with a roller on a top, and you've got yourself an intake.

Here's an illustration. Green is the frisbees path. Yellow is the elevator.

I'm confused as to how they push the blue frisbee up to make room for the red frisbee...

ajlapp 29-06-2013 22:37
Re: The Robonauts 118 - 2013 Video
 
The roller closest to the magazine just forces the Red disc under the Blue...

The incoming disc has enough force and the proper angle to lift the other discs up and out of the way.

Once the magazine is full it's lifted up about a foot to align with the shooter deck.

We had a similar floor intake plan (when we had a floor intake). We now use it to get discs from the feeder.

Watch the first 10 secs of this video. We were pulling in from the side of the disc but 118 uses a roller that puts pressure on top of the disc but it's the same idea.

1477 also moved to this system after Lone Star.

Abhishek R 29-06-2013 23:04
Re: The Robonauts 118 - 2013 Video
 
Yeah, we use a similar intake. Basically the rollers that are pulling in the disc have enough force to just push the rest of the discs up into the stack.
