This is what can happen when you make a kicker...

Re: 987 Kicker Destruction
 

Wow, certainly looks like you made it over the bump.

Re: 987 Kicker Destruction
 

It looks to me as though we have a winner folks.

Was that just pneumatics?

Re: 987 Kicker Destruction
 

Please knock over the tower with one of your high speed shots, event if you get red carded for field damage I think you could win the match just for the cool points they would award :D

Re: 987 Kicker Destruction
 

I think I saw tension from rubber or something... with pneumatics to pull it back?

Re: 987 Kicker Destruction
 

The video did not show energy storage phase. I presume manual method. The energy was stored in three (?) black rubber elastic straps on each side of the frame. No detail shows limit to kicker extension to the bumper outside dimension. Not certain either if the ball was more than 3" inside the frame. I think they were just killing time.

Re: 987 Kicker Destruction
 

If you guys dial it down a bit you actually might be able to keep it in the arena.
YEESH!

Re: 987 Kicker Destruction
 

Hahahahaha, nice.

We almost knocked out an illuminated EXIT sign today, luckily it was caged haha.

Re: 987 Kicker Destruction
 

You guys might be able to score across the field with that, provided you can aim it precisely (and the school lets you keep it that powerful).

Re: 987 Kicker Destruction
 

this is quite similar to what we are doing though our kicker is like a little foot xDDD

Re: 987 Kicker Destruction
 

So I know it has been asked, but how are you getting that power? Are you using pneumatics, elasticity, or both?

Slow mo studies
Slow mo repeat

Still can see some frames!!!!!!!!!!!! Its fast!!!

Re: 987 Kicker Destruction
 

I want to see how that works.

Re: 987 Kicker Destruction
 

those slow motion videos didn't do good for me. I just saw the kicker start, and then I saw it in basically it's finished position. It might be my computer, but I think it was the video.

Re: 987 Kicker Destruction
 

Fredi,
I was mislead by the title of this thread. You should change kicker to launcher. Another clock gives it's life to advance understanding.

Re: 987 Kicker Destruction
 

We had a part of our kicker going flying 15 feet into the air yesterday and land like a javelin in the nearby grass.

Careful when dealing with stored energy!

Re: 987 Kicker Destruction
 

We had a similar situation here on 868. We punched a HVAC vent back up into the ceiling testing our prototype. A few ceiling tiles also gave their lives for the cause.

Re: 987 Kicker Destruction
 

You are absolutely right about care needed to insure safety while testing launching mechanisms. We were careful to make sure nobody was near front of mock up launcher until swing arm was locked in place. Tight elastic bands/tubing help limit out of perimeter swing arm extension too...

Re: 987 Kicker Destruction
 

And watch those fingers! ::safety::

Re: 987 Kicker Destruction
 

Goodbye clock. Is Elgin next on the casualty list? [:

That's a lot of power, I'm interested in seeing how you guys are doing this. Pneumatics? Springs?

We managed to hit the light the other day (despite the shop's insanely high ceiling). Thankfully, it was already broken...

Re: 987 Kicker Destruction
 

When they shot the video the arm moved so fast that the camera could not capture the frames.....

Re: 987 Kicker Destruction
 

That's gotta be two spring.:) right Joe?
Specifically the pneumatics only as the release mechanism.
With that much speed (force) and a relatively small mechanical advantage, it must be.

Re: 987 Kicker Destruction
 

I ran outside when I heard "OOOOOOOOOOOHHHHH!" and "Let's not tell the mentors about this."

Re: 987 Kicker Destruction
 

Notice how the "foot", the part that strikes the ball, is always parallel to the ground? That is exactly how they teach you to chip a soccer ball.
This thing is awesome.

Just Lowes flat black bungee or surgical tubing snugly wrapped at bottom of arm with nearby frame:)

Re: 987 Kicker Destruction
 

robot win.

Re: 987 Kicker Destruction
 

Just give me a heads up as to where you guys compete so I don't volunteer for field reset... don't want your next video description to say "Goodbye Nica" ;)

Re: 987 Kicker Destruction
 

Yeah, they'd be disappointed that they'd missed seeing it in person!

Re: 987 Kicker Destruction
 

Similar story.

I was in the woodshop, I heard a loud "THUMP" followed by a "....tile still there? *everyone looks up and then down*"

*facepalm*

Re: 987 Kicker Destruction
 

This is probably more my fault than anything, but at least its a cool camera angle
