Shooting on the run

[gnirts]

I know that our team is definitely going to try to make goals while the robot is moving in any given direction.

How many other teams think this is viable?

Depends on how the shooter is mounted and or how the robot is built. I think it is viable to shoot on the run, however, not for the design my team and I have come up with.

I find it hard to believe that all teams can shoot at the center goal (at least at our regional I expect many teams, especially rookies, to go for the two lower goals).
... this is an anonymous poll!

There are only 22 results so far (a small sample size) and I think your results are getting biased by the fact that you made your title suggest that it was only a thread for shooting teams. Our team, for the record, can't shoot in the center.

Also, I'm curious why this went in the programming forum, or did I misread that?

Oops, my bad. I am not sure how to change the title.

Well, I figured two things would make that a logical choice:

1. If anyone on the team knows how reliably they will be shooting on the run, its the programmers.
2. And of all the people that visit Chief Delphi, programmers are probably on it the most. (just a guess, though)

definetly true

[greencactus3]

we defintly will be able to. but accuracy wise... i dunno if we'll actually do it in a match.

I doubt we'll do this (at least using camera control, our drivers can try it if they REALLY want to, but I wouldn't advise it). We don't have an accelermotor, and if we don't use the encoders either, trying something like this would be near impossible.

If you are talking about firing while moving, all you need to know is your speed, which way your turret is aimed in relation to the direction of the robot, which way the robot is pointed, and have tracking data on the green light. Maybe not even that much.

To build an effective anti-ballistic missile system, all you need to know is the starting point of the incoming missile, its boost, its average speed, its parabolic trajectory and its evasive capabilities. It's a simple problem...

Reminds of in the beginning of the season when the strategy team wanted me to use a combination of this year's camera, last year's camera, and an ultrasonic range finder to knock other teams balls out of the air

But on a more serious note, would you not also need to know where you are in relation to said projectile? And in FIRST, is knowing your exact position on the field less than trivial (esp. with non Kevin-ized accelerometer code)?

Good luck to all,

Does the robot have the mechanical capability to shoot on the run? Probably so. Does it have the electronics and software capability? Not yet, and not for a while if ever.

Whoever is voting for the first option, let's be serious here.

Unless you've been shooting on the fly in practice, on a full scale field, with robots interacting with you, you shouldn't be voting for #1.

I'd bet anyone on here a six pack of dew, or their favorite soda of choice that there's not a snowflake's chance in hell that 11 teams can repeatably make shots on the fly. Not even half that number. I'd be very surprised if even 2-3 teams could.

Why so pessimistic? Sure, practice is critical, but the physics behind it is not difficult with the help of the KoP gyro. What are your concerns?

Nevertheless, I chose #2 because I have not had the time to test anything yet... our robot is not evern wired!

Well, the mechanical is the hardest part! Now just figure out how much to lag the target by in degrees, and offset the turret by that amount from the green light.

Are team 476 can shoot while moving in a strait line towards the basket/
we can actualy shoot from anyware but dont count on any making it lol

not to mention using the camera for that has some major flaws like there are two green targets
traking the targets takes forever
and why when we have the lowest gear out there lol
well later if you have ways to get rid of these 3 probs idd like to know
