10 Balls per second?

[singerchic]

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!

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.

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.

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.

just a few things i lisend to this over and ooer and it dosent sould like ne thing legal for F.I.R.S.T.

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

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.

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.

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.

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...

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

[JoeXIII'007]

Ok, this is a little suspicious.
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.

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

[Bill Gold]

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.
