Did you use software to model that flight path? If so, what software did you use?

Truth be told this is a Frisbee not a ball. Two totally different types of flight patterns. Frisbees tend to curve after a while to the right or left.

If you are referring to my drawing, that is just a concept sketch done in paint. I have no idea if there is a feasible flight path along those lines that doesn't interfere with the venue ceiling, but based on my experience with Frisbees it would be a possible (albeit extremely difficult) shot.

We are not planning on firing from the load port at this time... I'll leave it to somebody else to point their shooter way up in the air and test the concept. :)

I'm waiting for someone to post a video of their prototype shooter doing this. Please, make my day. :)

Unless wind picks it up, don't you generally have to run forward to catch throws like those? o_O

(Cue venue installing massive fans in the rafters)

Or this.

to be honest, my opinion is that it's not plausible, in the case of throwing a Frisbee, the farther it goes, the more it curves, so my guess would be that's too far for the robot to shoot accurately

This is BA. I'd love to see such creativity be exploited for goal! Good luck with this design. Unique.

So from what I understand about the Paint schematic, the robot is firing backwards so that the curve takes it all the way to the other basket? Pardonez-moi, but I don't think a frisbee will do that.
Sidenote on the hammer:
If I'm the human player this year, I hope I'll be able to do that

Strategy: Park in front of uber-unstoppable robot. Stop shots. When necessary, go climb.

What are the other 2 robots on uber bots aliance doing? If they get in front of the feeder station in between your defender and uber bots disks leave close to the 60 and will climb quickly I dont think this will be easy to defend...

Thanks for the link. It makes me wonder, now, if there is any youtube video with a frisbie in it that has not already been viewed by an FRC team member. Also wondering if there will be a robot this year named "MC Hammer." (can't touch that stuff!)

From all these videos being posted of shooters shooting further than the length of the field accurately, how many cookies were you planning on giving out? :D

It seems reasonably likely (at least to me) we will see a fair number of full-court capable shooters based on all the videos people are posting. I believe the best shooting teams will just keep that as a capability on their robot and use it if there are no capable defenders against them as it's an incredibly high scoring strategy. Then if someone is capable or willing to play defense, they will just zip down field and make closer shots that can't be as easily blocked.

We are building a climbing robot first, shooting second and so our range is no where near this far. But in all our strategy sessions, we did talk about what we would do if it was a shooter first and it looked something like what I've posted above.

This is our shooter at full court and this is our shooter at half court

So many long range shooter videos.I think that if I had a full court shooter and needed to pick an alliance partner I would choose an 84" tall defense bot to stop this madness.=0

I'd rather pick an otherwise good robot (e.g. auto scoring, smart drive team, good reliable drivetrain, other strong defense tactics*) and put a 84" pole/net on top if we need it. Bonus if we can slap on a cylinder/steal a solenoid and make it go <=60" to 84". It's easier to get taller than shorter. Keep your CG low and be ready to become a 'wall' if need be, but I'm not sure why to make a big deal out of the ability.

That said, can you full court shooter get over an 84" tall defender if one of your (short) allies sits between you two? Depending on how high you shoot from, rising 24" over a span of 36-54" shouldn't be too bad. If you're accurate enough, you'd probably still score more than the two of you would individually otherwise.

*Climbing might be a trade-off with the pole.
