New Poll on What Are You Using
 

Now you can pick a shooting and intake choice, sorry for the mistake earlier

Interested in knowing what style intake and shooter your team is planning on using this year so I made a poll
Here is how I define the different styles
Intake:
ElToro- spinning horns/rods that feed ball from ground
Wheels- spinning wheels that go over ball and feed it into robot
Other- Please Explain

Shooting:
Catapult- Arm that throws ball like a catapult does
Wheels- Spinning wheels that launch ball out like last year and year before
Kicking Arm- Works like a foot under a soccer ball
Simbot- 1114 in 2008
Other- Please Explain

Thank You For Your Response!!!!

Re: New Poll on What Are You Using
 

Plan:
-Wheels + Catapult

Wheels since it will probably work well, and catapult since we got the prototype working today.

Re: New Poll on What Are You Using
 

A popular other option might be claws. Maybe a good idea to add if you can edit the poll.

Re: New Poll on What Are You Using
 

Haven't dedicated to anything yet, still in the prototyping and tuning phases, but we're kinda leaning towards catapult. Intake, we still have a lot of things to CAD and test.

Re: New Poll on What Are You Using
 

We've tested a ballista and are building a compound bow in addition to the shooter types listed. There's still time before final decisions need to be made.

Re: New Poll on What Are You Using
 

We tested a winch-catapult design but felt going with a motorized design similar to Boom Done was a better route.

Re: New Poll on What Are You Using
 

My team has been building a pneumatic shooter the past couple days. We had been running into the problem of not enough air to the cylinders to get the height needed. Today we added air tanks after the solenoids and lowered the mounting point for the two four inch long pistons and we had enough power to break a 2 by 4 in half when we dry fired. If your team is thinking about pneumatic I would highly recommend it, if you set it up correctly it has more power than you could ever need.

We're going with a winch pulled launcher that has a seat for the ball. The seat sits on top of a track, and the seat gets pulled back by a ratcheting winch, and when released, the seat moves along the track and stops abruptly at the end, therefore launching the ball. It's basically a ball puncher without the ball in front, but on top, if that makes any sense.

The track is on a pivot to allow for loading from the back, and aiming.

Just imagine an aircraft carrier catapult, or a crossbow, and you'll probably get what I mean.

The attachment shows a pic of an aircraft carrier catapult, and it follows the same idea.

This design was actually inspired by the linear human catapult I saw in the "Wipeout Zone" obstacle course on the ABC show "Wipeout."

Inspiration comes from the least expected places, don't they?

Re: New Poll on What Are You Using
 

This was one of the three main designs we pursued and prototyped on 2395 but we had difficulty getting the rig to work properly.
So we have opted to be like everyone else and build a catapult, because the prototype showed the most promise and the design was the easiest for us to build (not saying that's a bad thing).

Sometimes good engineering requires following the crowd.
Though we have a few ideas that might set it apart from the others of course ;)

As for the intake, we're not going with wheels, or the "el toro", but rather an older Dr. Joe inspired intake which is also going to have a Ninja Munkees twist :D

Re: New Poll on What Are You Using
 

Our team is the opposite, I guess. Our puncher works better than the catapults we've tried.

Re: New Poll on What Are You Using
 

Because your puncher has a fairly large surface area contacting the ball. That's the trick I think a lot of puncher prototypes are missing.

Re: New Poll on What Are You Using
 

I think you're right on that. The smaller surface areas put more energy into deforming the ball at a smaller point, rather than spreading it out on a larger surface for a more efficient push that deforms the ball less and more evenly, thus dedicating more energy to the launch.

Re: New Poll on What Are You Using
 

How many other people immediately thought of this right after kick off? During out shooter brain storming I pulled up a video of them dominating on Einstein. We also looked at their multiple uber tube in autonomous in 2011 just to prove that it is possible to score an alliance member's game piece in autonomous. (We're going big and trying to score both our alliance members balls into the hot goal this year. Or at the very least have their ball in our possession for the beginning of tele-op).

Re: New Poll on What Are You Using
 

Here's our system. The sound is kind of... bleh, but it's audible, nonetheless.

And I love that Team 1114's robot is a reccuring theme this year.
