10 Balls per second?

[KenWittlief]

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!

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!

If that is a robot ...... wow

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

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.

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).

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

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.

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!

[Bill Gold]

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.

[gondorf]

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.

[sdexp]

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.

[Travis Covington]

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!!

[sanddrag]

Somebody was saying I was over there in person last night watching this thing. I don't know what that was all about. 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.
