Re: What is the hardest (yet possible) task in this year's game?
 

i think (if i recall are math from lastnight's meeting) the farthest away you can be with the limit of 12m/s and still make the shot (no wind resistance) is about the halfway line. maybe a little more but no much.

Re: What is the hardest (yet possible) task in this year's game?
 

30 shots at the same 30 inch space in ten seconds seems like a midair collision to me. I agree with Billfred it just doesn't seem possible.

I actually have difficulty believing 10 in 10 seconds is possible without violating 12m/s with the first few shots.

Anyone that scores on the high goal while moving parallel to the plane of the goal while moving at least 5 fps. We aren't even going to try...

You could make this even more challenging by making it the first team to score more than five times per match using the above conditions.

Re: What is the hardest (yet possible) task in this year's game?
 

Human scoring will be harder than it might seem. We mocked up something last night and practiced to see how easy or hard it will be and I'll be surprised if anyone can score 10 consecutively. Scoring is achievable - consecutively 10 times in a row will be a challenge from that distance and with robots running around.

with a spinning wheel shooter you can launch balls as fast as you can hopper them into the input side

Ive personally seen a soccer ball shooter like this that launched them about 40 feet, and if you fed it fast enough you could have several balls IN THE AIR at the same time. It literally fired a stream of soccer balls.

One problem with this (I mentioned in another thread) the wheels do slow down when you fire a ball, so you either need a powerful motor to spool them back up between shots, or you need a big flywheel.

Re: What is the hardest (yet possible) task in this year's game?
 

Being realistic, I'd say that that's impossible.

If you were to somehow design an /incredibly/ accurate robot who could make 75% of its shots, you would still have to fire off fifteen shots in 6.8 seconds (less than 7) or 2.205 balls per second. And 75% is not realistic for an acuracy measure.

I would say a challenge could be to:

carry x balls (suggestion: 35-40)
make y% accuracy with a shooter(suggestion: 70%) (within some reasonable amount of time, though not really timed)

Re: What is the hardest (yet possible) task in this year's game?
 

What about scoring on your goal from the platform below it? There was lots of debate how this would never work before.

Re: What is the hardest (yet possible) task in this year's game?
 

Personally, I'm going to be looking for these two things. I bet they're even feasible.

1) One robot scoring all 10 balls to the center during autonomous.

2) A robot with a completely automated vision and aiming system, who can score >10 consecutive balls to the center during _human_ player mode. And I'd want to see these shots taken from at least a few different places on the field.

Re: What is the hardest (yet possible) task in this year's game?
 

I second that objective (notice i bolded and underlined "without" using a dead reckoning system).

First team to do it wins.

Let the games begin.

Re: What is the hardest (yet possible) task in this year's game?
 

I'd agree with that one. We measured the distance, and it was really far. I doubt someone could make 5 consecutive shots even without the wall in front of them.

Re: What is the hardest (yet possible) task in this year's game?
 

I'd say hitting the goal on the move, when not moving either parallel or perpendicular to the goal, so at some other angle than dead on or straight across as those are easy to account for, but when you not only change distance to the goal but also angle to it, thats tough, we thought about it, and it turns into such a painful calculation, it's probably one of the hardest feats in this game, whether in autonomous or in human mode.

Re: What is the hardest (yet possible) task in this year's game?
 

Okay, couple things wrong here. First of all, assuming an autonomous challenge, you could, by yourself, only shoot ten balls. Now, That is a ball every 7/10 of a second, which (look at you watch) is not that short a period using a flywheel to throw them. Now, the challenge assumes that you SHOOT the balls in 7 seconds, so you get three second grace period to find and lock onto the target. Sounds pretty possible to me, especially if you did it without moving from your starting position.

Re: What is the hardest (yet possible) task in this year's game?
 

I think you guys aren't taking everything into account when you say that 10 balls in 7 seconds is impossible. What about a 2 or even scarier 4 barrel launcher! We'd see some fast scoring.

Re: What is the hardest (yet possible) task in this year's game?
 

well, i think the hardest thing to do this year would be to block the center goal shots...our team figured out one of the very VERY FEW ways to do it legally....but we couldnt do it due to power issues... :(, i was looking forward to it

Re: What is the hardest (yet possible) task in this year's game?
 

for a little persepective on this, the max airspeed of the ball is 12 meters per second

if you fire balls at one second intervals they will be 12 meters apart in flight

thats ~40 feet apart. in the world of launched projectiles that is a HUGE space

I can visulalize balls flying through the air 2 meters apart, and all going in the goal - at 12 m/s that 10 balls in 1.66 seconds!

Its very easy to get tunnel vision, and only think of the problem in terms of what a human being can do

we need to think of this in terms of what a machine can do. A machine with a computerized targeting system, and 2HP at its disposal.
