So, effectively, you plan on taking, at maximum, about 6 shots? (Assuming your alliance wants to give you all six colored discs?

I think he means from the pyramid at the high or mid goal still

Oh no no. Sorry I said that wrong. We are not going to shoot at the pyramid itself, we are just going to shoot there so we are in the safe zone. We will be aiming for the 3rd scoring goal.

Ah right then. That would make more sense. What height are you shooting from, and will it be a variable height/angle?

In the video, we are shooting from about 3ft. And we are attaching lead screws to the shooter, so we can get any angle.

You may have a shot from one of the corners to the side of the top goal. alternatively, you might be able to shoot through the pyramids. With that much velocity, even accurate shots at the pyramid may glance/bounce off. Overall, very nice job!

Looks awesome.

I like your building.

[JohnFogarty]

Looks like this teams gets a cookie.

This video seems to prove that the full-court shooter is a viable (albeit somewhat easily defended) match strategy.

I say somewhat, because if you're touching that loading station carpet, you're untouchable, and if you design your shooter right at the top of your 60" envelope, you may be able to get enough rise out of your frisbees to clear an 84" robot just a few inches away.

That is very true! If your robot is not high enough, other robots could defend you at the loading station. Our robot (as of now) is only going to be 28inch tall. So we might have that problem. If so, we will just pick frisbee's off the ground and score at the 3rd goal.

I saw another strategy mentioned in another thread, and I think you might see some of the powerhouses make use of it in Eliminations at shallow-ish regionals.

Redabot1 is a 60" tall high-accuracy full court shooter intended to shoot from the loading station.
Redabot2 is unknown
Redabot3 is a short, weak box bot as the 24th pick.

Bluabot is an 84" tall blocker bot.

Redabot1 goes to its loading station with Redabot3 glued to its bumper on the shooter exit face.

Bluabot can get no closer to the shooter of Redabot1 than the length of Redabot3's chassis. This should give enough distance for Redabot1's DISCs to rise above Bluabot's 84" block.

[TheCrayButton]

Yeah exactly! That will probably happen. But I think there will be very few robots that are 60'' tall and can shoot that well. There are just a lot of factors that would make it unreliable. From my experience with FIRST, top heavy robots never seem to do well at all.

[JB987]

Or...Redabot 1 tips over well before reaching the loading station due to its raised cg.

[TheCrayButton]

hahaha exactly! That is what will probably happen. Our drive train has two speeds so we could easily ram someone that high and knock them over.

That's what my money's on.

If you look at our robot last year, on a 38X28 base, 60" was pushing it on how high we could go before becoming incredibly unstable. Granted, this was with a shooter on the top of the robot, but still that means that it will be very unlikely that any shooting robot will be successful with a height of over 45" tall. Defensive bots with light superstructures and a heavy bases made explicitly for blocking Frisbees can probably be taller than that, but they better be careful about it. If they even slightly out-build their base, they need to either have some sort of anchoring system, or be ready to end up on their side in a pushing match between them and the team they're blocking.
