I'd love to see a video of it if you have a chance to put one up!

I dont have a video of the shooter, and I dont know when I will be allowed to post one.

I do have a video of our method of delivering the ball to the shooter.

It is currently being powered by drills, but we will be using a CIM so the speed will be close. That shows about how fast we will be getting balls off.

3 foot max, we are money from whenever we are in range

[ZakuAce]

We're planning on about five feet maximum, but realistically, probably closer to three. I think with the orbit balls not having a uniform surface, and with your opponents always moving, getting a orbit ball beyond that distance will be quite difficult. Although it would awesome if some teams program their robot to lead the targets. That would be soooooo coooooooool.

Working on it....

we have a ways to go though

[spc295]

we are shooting 16ft line drives, but our we do not shoot as many balls per second as other teams. right now we are 93% accurate.

[Steven Sigley]

We do about 6 feet, much more than needed.

[Brandon Holley]

Range around ~ 8 feet

[midway78224]

Our turret has a 5-7 feet range

[Bob Steele]

We have a range, so far, of 6-8 feet... but we can shoot 2 balls at the same time... without much change in the distance...+- 6 inches

This just might be fun....

We were orginally looking at a 10 - 12 foot range but noticed two things we when started to test it out. First, after each shot, the motor and wheels would not get back up to speed and we would lose about 4 - 6 inches off each shot, so shots would start to miss after the first 3 or 4 unless we only shot 1 per second. Secondly, the longer shots tended to drift left and right due to the geometry of the orbit balls - even with a nice top spin. We were looking at about 66% - 75% accuracy with that configuration. So we regeared down to a lower rpm and greater torque - so the rpm recovery time was almost instanteous, and we found we didn't have any drifting. So we are looking at the 0 - 5 foot range for shooting effectively. We can shoot 20 balls, with almost 100% accuracy, in less than 6 seconds at those distances.

Glenn - have a great season - too bad we will be at a regional with you guys this year! I wish you all great success!

We're also working on a speed sensor for the shooter, to keep the shooter wheel rpm constant.

[JesseK]

At 620 rpm, we were at 7 feet with 75% accuracy. However, that was just our latest prototype. The real thing will be ~4200rpm max with guided rails for more accuracy... so we'll see

Of course we're scaling it back down to 10-12 feet for accurate shots, and 3-4 feet for maximum throughput. I do like the idea of a miraculous cross-field shot though...or a 'rain' of orbit balls from 20 feet in the air .

[Drake Hunter]

Ours is shooting at 8 feet with about 98% accuracy

[Taylor]

We got 5 inches, 100% accuracy.




We're now re-gearing our shooter.
