Ideas for shooter
Our team has come up with an initial design for our frisbee shooter (we're yet to come up with a device to pick up the frisbees). It's similar to the shooter in this video: http://www.youtube.com/watch?v=bRBg-...u8SDSA&index=1
What do you guys think of this? What is your team planning to do in terms of strategy? Are you going to aim for the highest rack or are you trying to nail as many frisbees as you can into the lower and middle slots? Are you going to shoot the frisbee or just put it through the slot with a manipulator? Good luck everyone! |
Re: Ideas for shooter
I have thought of the same idea. What do you guys plan on doing to climb the pyramid? And picking up frisbees from the ground. Does any one have any blueprints that they could show us?

We haven't thought about climbing the pyramid that much yet. But for picking up the frisbee my idea is to have two wheels rotating inwards and then we drive over the frisbees to pick them up. Another idea is to have a metal plate tilted towards the ground and we go to a frisbee, tilt the plate a little after some of the frisbee is on the plate.

Re: Ideas for shooter
Won't the frisbee tilt, and what happens if the frisbee is upside down or slanted against a wall?

Re: Ideas for shooter
There will probably be lots of missed frisbees on the ground. I think a speedy bot with capabilities to pick up missed frisbees and dump them in a low goal could prove useful. I suggest looking at old overdrive designs to maximize maneuverability for low scoring robots. And maybe incorporate a basic hanging device for an additional 10 points.

My teams stratagy for shooting is the middle goal. Much like the middle hoop in last years game, the middle goal is a small distance from what the height of the robot can be (it is just over 4 inches) so far, one of the ideas is to shoot at that goal quickly from very close to the wall.

Re: Ideas for shooter
anyone know how big of an effect there is if the frisbee is thrown upside down, or any ways people are planning on flipping them?

Re: Ideas for shooter
We tested out if we can throw the bee upside down, but found that the bee curves a lot and experiences a lot of drag this way. The only way to counter this is to put absolutely no spin on the bee, which is pretty hard.

ok thanks

Re: Ideas for shooter
My team had the idea of doing a sort of rail gun design if you can call it that. We have a vague idea of how we're going to go about it. We're deciding on whether to go pneumatic or use wheels like a pitching machine which we did for Rebound Rumble. This will obviously be more guided since it is a frisbee we're shooting, hence the rails. Just wanted to put my idea out here. This is my second year in FIRST and my team's fourth year so we'd like to help as much as we can even if it's just a small amount we can give.

Re: Ideas for shooter
The only problem with shooting for the bottom goal is that you have a limited ammount of frisbees to score in a match. There are only 51 ish per team plus the ones on the field at the start, that is not a lot of attempts to get a high score, and if you take all of your 45 and score one than the other team only has to score 1/3 or 1/2 of that to tie you.
*edit* Tonight we built a prototype shooter and had fantastic results! http://www.youtube.com/watch?v=LD9Ic_rBRmk Theres a video |
