10 Balls per second?
 

10 balls per second!!!

So, what do YOU do with the remaining 9 seconds of autonomous?

Re: 10 Balls per second?
 

Yes, ten balls per second is impressive, but how are you doing it at this speed.. can you get up a video of the robot also?

Re: 10 Balls per second?
 

Please, that would ruin all of the fun... this IS the rumor mill afterall. ;)

Re: 10 Balls per second?
 

What really is the advantage of shooting in all 10 that fast? What do you plan to do afterwards? Sit there? Try and have the robot block another?
I mean, personally, my team will be glad if we can accurately shoot 10 balls within the auto mode time. As to how fast we'll do that, that'll depend on how quickly we setup our system.
I guess this just raised that old speed vs. accuracy thing in my head. But it seems like the accuracy was good here eh?
It also seems like all the balls were shot from the same point (they all seemed to follow a close arch) what about the advantage to being able to shoot while moving? (did I say that out loud...)
I'm not trying to be negative, it looks really kool (assuming it's even a robot :rolleyes: ), I'm just trying to toss some thoughts out there...

Re: 10 Balls per second?
 

hehe, ive been wating for a video like this. Im pretty sure our launcher could do something similar, but no way to test since were 9 balls short :D

Re: 10 Balls per second?
 

Dang Travis. That's some impressive stuff, being only a week into the build. Would you maybe want to IM me some more pictures, videos, or CADs over the next couple days? It'd make my job a whole lot easier. ;)

I, for one, am looking forward to seeing another amazing robot from 968 this season. Talk to you soon, man.

-Bill

Re: 10 Balls per second?
 

Well it's certainly theoretically possible. A ball going 12 m/s has 15 J of energy. At peak power, the small CIMs put out 340W. So if you transferred energy 100% efficiently, you could actually fire off 22 balls per second...

Re: 10 Balls per second?
 

The advantage is not being in the way of your alliance partners when shooting. If 968 puts their balls in the goal during autonomous in 1 second, that leaves 9 seconds for their teammates to shoot. This is an excellent strategy if the accuracy is as shown.

Great job 968, and thanks for posting it!

Re: 10 Balls per second?
 

theres only 9 seconds if they were exactly lined up with the goal at the beginning. you are forgetting that it takes time to move from the start and aim at the goal.

Re: 10 Balls per second?
 

Still, having a robot that fires way faster than it can gather and load seems to only be an advantage when it's pre-loaded (i.e., one time during the entire match). For example: you can have the fastest machine gun in the world, but what good does it do you if you have to reload every .5 seconds?

Re: 10 Balls per second?
 

You score more points. You have more time to collect balls and play defense.

Re: 10 Balls per second?
 

hmmmmm well even though the video is 2 seconds long you can get a bunch of info from it

1. The video there showing is from a head on shot not a side shot so this auto mode will take more then 1 sec.
2. you can hear the balls but nothing shooting them
3. the ball are falling down not shooting up

nice try guys i hope you can pull it off but this is not a robot shooting balls

shaun

ps there a ton more evedence in the video of why this is not a robot cannon you will see in a comp look carfully.

shaun

Re: 10 Balls per second?
 

Still, let's say your aim is off. You miss and have to reload. With a slower firing system you'd have time to adjust (In autonomous a quick firing system would be an advantage, since you don't have a lot of time and can't move the robot with the controls anyway.).

Re: 10 Balls per second?
 

I wouldnt assume things like this so quickly, im impressed and cant wait to see 968 in competition.

Mind tricks on CD?
 

*Hand wave*
There is no robot.

Wetzel

Re: 10 Balls per second?
 

On my PC I definately hear some type of machinery running before the balls hit the goal.

If the balls have been fired from ground level they will arc up in flight, then they will be 'falling downward' on the tail of there flight - so I dont see any evidence that proves this video is contrived.

very impressive!

being able to launch ten balls at once means you have more time for everything else

and for dramatic effect you can use the first 3 second of auton mode to get into position, wait 6 more seconds, then fire them all off. The most dramatic shot in basketball is the one that just goes in as the buzzer sounds

in your case, it will be ten going in.

excellent demo. This will definately get some people thinking out of the box! Engineering is like magic sometimes. Once you see someone do something impressive or new, you know there is system behind it, so the challenge then is to figure out how they did it.

BTW: Nobody would take the time to setup an elaborate shooter hoax/con and post it on CD, when they are so busy working on their robot. "Hey instead of working on our robot this morning, lets make a fake launcher video and post it on CD to freak everyone out!" I dont think so!

Re: 10 Balls per second?
 

You cannot "Drop" balls into a goal like that per-se. They must be shot somehow. It doesn't mean that they have to shoot them UP, but they must be given some forward motion. Also, it looks like one of the balls reaches it's apex slightly after it enters the frame, offering evidence that they were shot. I'm going to say this is not a hoax, and to be VERY VERY affraid!

Re: 10 Balls per second?
 

If that is a robot ...... wow :ahh:

Re: 10 Balls per second?
 

They wouldn't??? :confused: You have just got to love the rumor mill... :D

Re: 10 Balls per second?
 

thats the word on the street ! :^)

Re: 10 Balls per second?
 

I see alot of shooters early but none of them on robots. Ours on the other hand can shoot 1 evey .5 seconds at any of the starting points for a total of 10 ball in 5 seconds. tough to stop that. then it will go out and find other robots :) yes find other robots. the camera is great for other things then the green light. :D

Re: 10 Balls per second?
 

The advantage to shooting that fast?
1-you can ideally unload all your balls before opposing robots have time to move to try and either block them or dislodge you from your shooting spot
2-can funnel them into the goal far far faster than a HP can take the out and return them to play, therefore giving a HUGE advantage in the last few seconds of the match
3-makes it so even the slightest mistake of the opposing defense can cost them massively
4-allows you to "get in and get out" reducing the chances your opponents have to trapping you into their zone and even possibly pinning you onto their ramp area
5-allows for longer set up and positioning time (if needed, some robots may be fully capable of "sinking shots" from the starting position) during autonomous
6-is really freaking sweet


and here is arguably the most important of all:
7-allows for more reload time. Even if you discharge your load quicker, you can still hold the same amount of balls (in theory, the reality may differ on how you load the mechanism, and this creates a debate in itself of whether quick shooting/loading vs larger quantities of "ammunition" is the better way to go). Therefore, the faster you can unload your balls, the more time it will allow you to refill and shoot again (or do other various tasks around the field, such as defense or going for the platform at the end).

Re: 10 Balls per second?
 

I'm pretty sure thats not 12 m/s. And the angle that its coming in at is pretty high too.

Re: 10 Balls per second?
 

As we have no true indication of where the balls are being shot from and the release angle of the mechanism shooting them, it could be 12 m/s. The balls seemed to be cresting as they went through the goal, suggesting that it may be a appropraite speed shot, but the launching device may be more than 60" high.

Re: 10 Balls per second?
 

hey
we were checking this out and messing with the video. we dont believe this for one second!!! the video is reversed and u shot the balls through the other side of the hole. better luck next time! :D

Re: 10 Balls per second?
 

Actually, I can verify for a fact that this video wasn't tampered with at all. I saw the mechanism last night along with some other videos, and this really is 10 balls in pretty much one second.

Re: 10 Balls per second?
 

how can they all go in in one second... i mean i can see them all firing in 1 second but in the center goal they would all just pile up and not actually score. how did you make them all go down the tube at once? i think that although the firing mechanism is good in order to make it realistic you would need a back to that goal

cool idea however. if you can make it work tell me because my team could use help trying to fire 1 ball per 10 seconds

is it true that also using tracks can help fire more accurately? this is definitely a rumor.

Re: Mind tricks on CD?
 

The question is, why would you risk taking too much power for a risky shot of ten balls in a sceond?

And yes, the clip didn't have a robot--or at least a regulation robot.

Re: 10 Balls per second?
 

This IS a real mechanism, but is not neccesarily mounted on a robot. The top of the 'device' was 60" off the ground. It uses a single 7" wheel spinning at ~1750rpm. The balls exit the device at around 35 degrees. It would shoot faster if we had a method of feeding them faster.

Please remember, I could have easily posted this in the robot showcase forum but instead chose to post this in the rumor mill!! :cool:

Re: 10 Balls per second?
 

Somebody was saying I was over there in person last night watching this thing. :confused: I don't know what that was all about. :rolleyes: Anyway, I think everybody designing their mechanisms has a good benchmark to meet, and some serious competition to watch out for. And I'll verify what Travis said about the feeding.

Re: 10 Balls per second?
 

(I didn't actually run these numbers) But if you did run the CIM that fast then wouldn't the first balls out exceed the 12 m/s speed limit?

On another note, I also hear machinery running during the film. I can hear a soft "thump thump thump thump" before they start appearing on screen and traveling towards the hoop. Presumably noise made from exiting the shooting mechanism.

Re: 10 Balls per second?
 

* This Robot powered by Divine Intervention *

(and WD - 40 )

Sure.....but
 

keep in mind that it will take a while to spin up a wheel to 1750 RPM, so by the time it speeds up you may only have a second or two to shoot all the balls. Total time to shoot 10 balls is not 1 second, but 1 second plus the time to speed up the wheel (perhaps almost 10 seconds depending on how you design your system)

Yes, if you just let a wheel go at the full speed of the large CIM it may provide too much velocity, but it depends on the wheel diameter (well, actually the radius really).

My calculations (which I will not post here) show that you have to be a bit careful with the diameter and inertia. However, there will be plenty of energy in the wheel to fire off a bunch of balls (remember, its not just the motor power that is shooting the balls, but mostly the energy already stored in the wheel which is really a flywheel). Its almost a given that you will have plenty of energy to shoot all the balls when your wheel is up to adequate speed to give you the velocity that you want.

You might want to consider gearing for the wheel as well - my calculations show a real benefit to this (but you will have to figure out just what it is). I will leave it to you to do the energy, inertia, speed, and power calculations.

Dont forget that the velocity of the balls will be slightly different as well since as the wheel slows down with each shot, the subsequent shots will be a bit slower,which means that the range will make a difference as to how many balls you can actually get into the goal when shooting them that fast.

Re: Sure.....but
 

Not really...the regular CIMs spin somewhere between 3000 and 5000 rpm, and you can spin them up (attached to a 6" wheel) in less than a half second. If you're gearing it with sprockets or using a heavy wheel then yes it will take longer, but i don't think it'll take more than a second or two

Re: Mind tricks on CD?
 

You'd be wasting balls, not really power. It doesn't take that much more power from the launcher to launch 10 at that rate. They only have to run the device for 2-3 seconds top maybe to launch 10 balls, including acceleration. To launch 1, you reallistically couldn't cut it off in under a second, especially factoring in acceleration. In fact it's probably far less energy than having to re-accelerate the motor after each shot or spacing the balls out so they shoot rougly 1 per second. The same pretty much applies for whatever feeding mechanism you use. Rate of fire has alot more to do with how you feed the balls (or prevent them from being fed pre-maturely, aka when the motors are accelerating up to speed) than the launcher itself.

Re: 10 Balls per second?
 

what i might want to ask is with this mirical and ingenious shooter mechanism, how are the balls aimed. can the camera sync with that many shooters?

this is just a question.

also this mechanism: does it use pneumatics as a feeder? it seems like the nly thing fast enough.

jury rig wheels to the bottom. that would make a killer robot that would probably win

Re: 10 Balls per second?
 

Actually, I do hear a sort of dull thud right before the balls come flying, and it sounds like its real...but I'm going to say there is no bot that can pull this off.

Like you said, they look like they are falling down. For them to be doing that, they would have to be exceeding muzzle velocity constraints. And the shot is very jerky, like it was sped up.

I dunno for sure, but I'm pretty sure this is fake.

Sorry if its real, so offense...

JBotAlan

Re: 10 Balls per second?
 

just from watching it with out sound it looks like its been made faster and played backwards. and as for the upside down part, unless they put a light on the floor, how do you explain the glimse of light at the top?

I think its real but a tad bit altered and not mounted on a robot.

But then again it could be anything

Re: 10 Balls per second?
 

Ok, this is a little suspicious. :rolleyes:
The balls are coming from the same area, there was a slight delay between the first and last balls, and there was a lot of static noise in the video.

I'm going to theorize that 968 decided they had a little spare time at the end of their day, parked something in front of the goal other than a robot, and then let it rip.

Yet again, that's just a theory. Good luck to 968 and all teams! This game will prove to be interesting when it comes time for competition.

-Joe

Re: 10 Balls per second?
 

It could be gravity fed ;)

Re: 10 Balls per second?
 

actually i dont think gravity would be fast enough to feed at THAT speed.
i mean doesnt gravity have a limit? it would already have to be moving downward to hit that velovity to feed them in that fast.

Re: 10 Balls per second?
 

Re: 10 Balls per second?
 

actually this mechanism would be perfect defense.

it could shoot balls straight up and catch them and just park in the center goal and knock out any balls shooting for the goal by bouncing them against one another.

Re: Sure.....but
 

compressed air assist? :D

Re: Sure.....but
 

Doesn't it take time to compress the air as well?

EDIT: actually now that I think about it I remember something about being allowed to start with the tanks full.

Re: 10 Balls per second?
 

if you play the first video in this thread backwards and turn the sound up loud

you can clearly hear the voice of John Lennon saying "I am the eggman, I am the eggman, Koo koo Kachoo!"

totally freaked me out!

Re: 10 Balls per second?
 

The compressed air is just because they didn't want to get their hands too close to a spinning wheel and chains.

Re: 10 Balls per second?
 

Great... now I'm going to have to try this.
How exactly do you play the movie backwards anyway?

Re: 10 Balls per second?
 

Quicktime should be able to do it, but i don't know if it does the sound too...i'll check tomorrow

Re: 10 Balls per second?
 

I dont think it works. I put it into Adobe Audition and split the audio file out. I inverted, reversed, and both togethe and i still dont get no koo koo cachooo.

it hut :( lol. makes a cool drum beat though.

Re: 10 Balls per second?
 

Ummm, wow.

Unfortunately, you cannot always tell when some things are jokes on forums, because we only can rely on text and a limited number of similies. But Ken's post about playing it backwards and hearing John Lennon was a definitely funny joke and nothing more. But it is funny to see how some people take everything they read and believe it to death. :yikes:

Re: 10 Balls per second?
 

and where the info is posted (in the 'rumor mill' threads for example?)

Re: 10 Balls per second?
 

I did because i was bored. I knew it was probably a joke. I have too much free time on my hands when my robotics class doesnt meet today because of the holiday and i didnt have to get to bed early last night. I went to bed at like 3 am. which is late for me, unless i pull the all nighter.

Also, my music editing software was already up, and i thought it would be funny.

Re: 10 Balls per second?
 

FAKE, I got PROOF it is a Fake. Check out the attached pic to explain it all or read and/or read explanation. Look at the bottom of the goal. watch as the balls to 'throuth the goal right', as they cross through the goal and WE KNOW that the balls go into the goal, disappear as they are blocked from view by the bottom of the ring and reappear in the gap and then disappear again when they go behind the stand. However, they are being caught by a guy standing IN FRONT of the goal into a garbage can. NOT POSSIBLE. TOTAL FAKE.

I suspect they overlayed 2 videos. Look as the video is playing at the where that midle arrow is pointing, that 1 top of a ball glimpse is there for a while in the video. Any other guesses on how they faked it?

I suspected fake in the first place because he said it was in the rumor mill not robot showcase.
Yeah...real as a SOFTBALL LAUNCHER!!!!! :cool:

Re: 10 Balls per second?
 

Yea I just noticed that, I had to watch it multiple times to understand what I was actually seeing...

Re: 10 Balls per second?
 

i actually believed it because i am very gullible.

also i want to try and find a way to get my team out of the time hole.

so this really isnt real? it seemed it

Re: 10 Balls per second?
 

if you watch the video, you will see that the trashcan is held by a guy standing behind the goal, and in the frame you posted, he is blocked from view by the man standing in the foreground.

i find it disappointing that so many of you have trouble trusting your fellow FIRSTers. several reliable people have said that this video is not a hoax. maybe y'all should spend less time over-analyzing freeze frames of a teaser video, and more time on the 'bot. i, for one, plan to fire 15 balls through the goal in under a second. eat your heart out, travis ;).

Re: 10 Balls per second?
 

how do you jam the nerf balls into a softball launcher ?!?!

Re: 10 Balls per second?
 

You have nothing but ego. Curb your jealousy and go build a robot.

Re: 10 Balls per second?
 

i feel that just the fact that they were able to launch that fast is amazing. my team cant launch 1 ball in 10 seconds let alone reversed.

dont disrepute the idea with saying "I have proof its fake". the fact of the mystery is why it is in rumor mill, not the robot showcase.

Re: 10 Balls per second?
 

I watched the video - I see what you mean.

the plywood that the guy with the garbage can is standing infront of is a crate or something in the background - its not attached to the goal.

It does look confusing because you cannot measure depth in a 2D video like this, and the crate and the goal are the same color plywood. If it was shot from the side you would see:

Crate______Guy with can______Goal_______<balls going left____Guy by launcher.

the simplist explaination in this case is the correct one.

Re: 10 Balls per second?
 

Here's my take on it. Whether is is a robot or not, that is 10 balls, going through one hole, without any missing, in a very short period of time. Quite impressive I must say.

Re: 10 Balls per second?
 

Yes, it would make sense if it is a crate back there. However, there still isn't any proof that anything they could put on a robot will do this. And the sound is still puzzling me, count how many wooshes you hear during launching. Can someone split this and get a sound print picture to count them? Versus how many balls are launched, I think I count 7 wooshes but only 5 balls. What is that voice saying in the end, why is there a crash at the end of the launching?

I suspect they have some laucher set up with a tube full of 10 balls. Turn it on and have a kid push down on the tower of balls and quickly force them all into the launcher part.

The sound sucks in the first video it does 2 different tones it starts boop, boop, boop, then goes beep, beep, beeep. The second half sounds like drums and the first almost like a xylophone. I suspect the first was sped up and reversed. And also look at the balls going in, wouldn't a mechanical launcher to it more uniformly instead of having 2 go in a the same time?

Re: 10 Balls per second?
 

the launcher is 100% real. I know this because i made it. it is roughly based on a pitching machine. And it is possible to have a version mounted to a robot.

See yall in competiton.

Re: 10 Balls per second?
 

But in the second vidoe, you only launched 5 balls in my guestimated .7 seconds, and I don't quite trust the first video enough. Ok, the launcher is real, but does it 100% launch that many balls?

Re: 10 Balls per second?
 

Settle Down folks.

#1, if it is not a fake, very impressive, but... ...it is not terribly different than the Rage Team showed with their videos.

#2, if it is a fake, so what? ... ....it is not terribly different than the Rage Team showed with their videos.

#3, let's all try to keep from liable and name calling... ...it is not terribly different than those So and So's over at Rage Team showed with their faked videos - JUST KIDDING!!!

#4 settle down, seriously.

Joe J.

Re: 10 Balls per second?
 

Even if it isn't a robot doing it, it proves it can be done. And therefore, there is a high probability that a robot can be built to do it.
So what if it's a fake, it's THEIR time they are using to make a fake video, and its YOUR time you are wasting arguing over it. If it's fake, they can't use it in the competition against you anyway, so get over it...

Re: 10 Balls per second?
 

Rage's device is more impressive than ours, bottom line. What is really funny is that they posted their videos in the Robot Showcase forum, and I posted this in the Rumor Mill. The forum heading has to lead you to SOME conclusions...

Re: 10 Balls per second?
 

We have something to be just about that quick...you will all see it soon enough.

Re: 10 Balls per second?
 

ya, rage's video is wicked sick. And I think I figured out how it works. I'll give you a hint: look at the fan in a leaf blower.

Re: 10 Balls per second?
 

All I got to say Is be afraid, be very afraid :cool: :ahh: :yikes: :eek: :rolleyes:

Re: 10 Balls per second?
 

Team 1327's first try got under 3 seconds. Still need more control for aim, but proves that it is possible to get close to 1 second.

Re: 10 Balls per second?
 

Hey that is good! We can only shoot 5 balls per second :( How did u do it???

Re: 10 Balls per second?
 

Wow! Good work, guys!

Re: 10 Balls per second?
 

We are still working on our mount for the robot, but this prototypye used two wheels powered by using one stage of the standard transmision and the CIM805-001 (small CIM) motors. this provides more than enough power and requires the controller to "throttle down" the power to keep the wheels spinning at the allowed speed. The wheels are 12" pneumatics from a previous years robot. Now on to making the mounts for the robot. From our testing it appears to be important how the balls enter the shooter as to how straight the ball will shoot.

Dave

Re: 10 Balls per second?
 

Don't forget that for every ball that comes out of your shooter, one has to go in first. While these rapid-fire videos are quite impressive looking, I am curious to see how any of you will be able to load the shooter that fast. Seems it would take some time to raise the balls into a shooter, and if the balls are already above so gravity does the work then your shooter is somewhat below the the top of your robot - allowing for shot blocking. :yikes:

Re: 10 Balls per second?
 

10 balls/second- ok

but from where?

they don't seem to be too far out there........ and you need to get to the shooting spot first

WC :cool:

Re: 10 Balls per second?
 

A shooter may not be able to pick up that many balls for this to be a huge advantage. but what if an alliance harvester can transfer balls effectively to this shooter say 30-40 balls?

My team is making a harvester trying to do something similar to that. I even started a discussion trying to find out how are most shooter's ball container built so we can transfer balls effectively to most shooters.

http://www.chiefdelphi.com/forums/sh...ad.php?t=42586

Re: 10 Balls per second?
 

to posters: why are you arguing with this team? do you really care if they faked it? or if its real? is this video going to change your team's design?

to team: very nice. if it was done, very cool. if it wasnt, thanks for distracting other teams for 6 weeks.

Because it's amusing to speculate. It's also interesting to try and have an idea of what you'll be up against, whether or not anyone decides to change their design because of it.

Re: 10 Balls per second?
 

Way to go.

One observation: what if the aim is off when you decide to commit?

Re: 10 Balls per second?
 

You silently swear in your head and hope your alliance members don't kill you!

Re: 10 Balls per second?
 

Good point.

However, I would pray that I would that the offense would be able to harvest the balls faster than the defense will. 10 or 15 rapid fire misses can easily turn into 10 or 15 fast, free points with some robots. It's those points that can determine the difference between winning and losing, sometimes.

Re: 10 Balls per second?
 

Just wondering, but has anyone seen this robot at competition? I'd really like to see their design and hear how well it worked. Thanks.

Re: 10 Balls per second?
 

Im pretty sure there have been bots at regionals that were able to accomplish 10 balls in the center goal in auton mode.

Anybody keeping track? it is a very impressive feat if your bot can pull it off.

Has anyone achieved 10 balls in one second? what is the fastest shooter so far?

Re: 10 Balls per second?
 

I dunno if it is the fastest, but both 254 and 968 can unload a metric boatload of balls in the blink of an eye. Is that precise enough? One of the secrets of their shooting speed is running their ball feeder using a CIM at what might be full speed. The balls are accelerated to a substantial portion of shooting speed before they get to the shooter wheels.

Re: 10 Balls per second?
 

team 1726 MegaMaid seems to do the 10/second thing, or close to it...but in a low goal from starting position. Uses a CIM at full speed turning a 4" pvc roller that's wide enough to feed two balls at once

Re: 10 Balls per second?
 

We had one match at Annapolis where two robots put 50+ points in the center goal during auton. What really sucked was that the field software failed and no green lights came on so the match had to be restarted.

Wetzel

Re: 10 Balls per second?
 

25 shoots about 10 balls in 2 seconds which is still rediculously fast and gives 7-8 sec for the camera to find its way =P

Re: 10 Balls per second?
 

Our bot has a vertical lift which draws balls out of the hopper. We can hold up to twelve balls in that vertical lift. We can clear out the lift in a second. We have a "double barrel" shooter so in the best of conditions, if our lift is full, we can shooter 12 bps.

Re: 10 Balls per second?
 

Depending on how the balls are loaded (we have three parallel shooters), Team 95's bot can shoot around 10 balls a second, although it's more accurate if they are all loaded in the center hopper.

Re: 10 Balls per second?
 

Well, the competition is over, was it real? Did they fire the balls at 10 per second?

Re: 10 Balls per second?
 

968? no. 968 and 254 shot around 5-6 balls per second.

469 shot very close to 10+ balls per second.

Re: 10 Balls per second?
 

Team 95 was about as fast as I've seen. They were easily 10+ balls per second.

The video was played forward, and was only sped up a little bit. The rig that was used to launch those balls was made with a bench grinder and an 8" skyway wheel. HP was about the same as the 2 small CIM motors, so theoretically we could have shot 10 BPS, but didn't deem it neccesary. They were already falling out of the goal at 5-6bps.

Re: 10 Balls per second?
 

Team 95 didn't go to nationals, but I know there were several times we shot 10+ balls per second. I've got several pictures showing 6 balls airborne between the bot and the goal (less than 10 feet away), and one picture showing 9.

However, we didn't get to do this (shoot balls from all three hoppers at full speed) all that often (watch the Palmetto finals to see the winning alliance going out of their way to block us and keep us from aiming). But when we did get to shoot, the results were impressive (we won a semifinal at Palmetto that way).

One time in the pits, the bot (Lilly) was fully loaded, and could send 42 balls from the hopper to being at the target in around 3.5 seconds.

But nonetheless that is very impressive... I saw a bot on one of the webcasts that looked like it has a burst mode, like James Bond's Weapons from a 007 game. It was spectacular and was one sight to see. :)

That would probably be 469, Las Guerillas. When they unloaded it was one of the most frightning volleys in FIRST.
