Team 1646 Shooter Prototypes Video

Over the past week, 1646 has been playing around with different shooter variations to see how the ball would react. Check it out.

Warning: video features gratuitous amounts of Kyle Love.

UNHH SON!!!!

Nice! Do you plan to build a goal (trailer) and see how it performs with topspin, backspin, and neutral (two rollers)?

Re: Team 1646 Shooter Prototypes Video
 

Yes, the trailer was finished after the videos were shot but we were simulating the best we could at that point. We found we got the most distance when we ran them at the same speed. When we tried putting some backspin on the ball by running one slower, it didn't shoot very well, but we also didn't spend a ton of time on that either so I'm sure it could be perfected.

Good work guys!

Our shooter is producing very similar results.

Was the shooting the ball into a ramp part of an initial design consideration or was that just a quick way to prototype launch angle?

Thanks for posting this! It will be very helpful as a frame of reference for teams who want to use shooters.

What gear ratio did you use on the CIM (looks like 1:1)?

Re: Team 1646 Shooter Prototypes Video
 

One improvement, when the ball is going to the goal in slow motion, you should play chariots of fire...

but in all reality nice design

"Sorry, this video no longer exists":(

I'd like to watch...

Re: Team 1646 Shooter Prototypes Video
 

Try again...Worked fine for me. :)

Re: Team 1646 Shooter Prototypes Video
 

both prototypes used an AM Gen2 gearbox in high gear and a 1:1 sprocket reduction, so I think the reduction is 4.17:1. I know some other teams run faster, but we figured this gives you some torque to keep the wheels up to speed if you're planning on firing a lot of moon rocks in a short span of time (wink wink nudge nudge);)

No chance...

I tried with Firefox, Safari and IE and couldn't see...
May be some problem with IP range????

Re: Team 1646 Shooter Prototypes Video
 

A little of both really. We just used a bunch of wooden boards to see how much the ball would compress and shoot. Eventually it gets to the point where the ball is compressed too much and springs out as it's coming out.

Re: Team 1646 Shooter Prototypes Video
 

Some say "More Cowbell" - I say "More Kyle Love"

Re: Team 1646 Shooter Prototypes Video
 

Yeah we discovered the same thing...Our prototype allowed for compression of the ball from 5 inch up to 9 inch, so we saw how the ball reacted at a bunch of different compressions.

i agree with Mr. Taylor needs more "uhh son!"
