3322 Shooter
Video of our practice shooter hitting the high goal multiple times. Note that the target is a bit higher than normal, as our practice bot was not completely assembled as of the time of this video. Credit for the video goes to Tommy on 3322.

Re: 3322 Shooter
Good job guys! Reminds me of that great shooter we had back in 2012. Good times. Next step is a 2 ball auto, right??

Re: 3322 Shooter
My team has a shooter very similar to that one. What are you guys using to achieve that accuracy rate?

Re: 3322 Shooter
Haha we can always dream of that. Could be too risky going over the centerline.

Re: 3322 Shooter
Impressive accuracy! Looks like the ball is coming out with front spin, so I'm guessing single wheel on top?

Re: 3322 Shooter
How far out are you guys from the goal? From what I am seeing it was shooting from pretty far away. Good job.

Quote:
It's a two-stage* shooter using a pair of 3.5" colsons on each stage and a lexan-surfaced hood. Each stage is powered via belt by a 30:18 geared up miniCIM. Currently the motors are open-loop. We'll be closing the loop and implementing speed control real soon. Release angle is around 35-40 degrees to the horizontal. This particular shot is from the defence "safe zone."Here's the best picture I have at the moment. Intake was between revisions at this point. *In my opinion, this is the key to this shooter's accuracy. More time for the ball to reach shooter wheel speed means less slip, less slip means less variation in shot between balls. |

Re: 3322 Shooter
I didn't think I knew how to give an accurate answer to that, but I can mention that no closed loop programming has been done yet.

Re: 3322 Shooter
Shooting with the back of the bot touching the outerworks (approximately)

Re: 3322 Shooter
Great job, guys! My only question is - are you using a wheeled shooting mechanism? And if so, are you using horizontal or vertical wheels?

Re: 3322 Shooter
The wheels are vertical. There are two stages, each with two 3 1/2 wheels. The first stage is a little slower than the second one.
