Poll: do you have a turret

[Rickertsen2]

Does your robot have a turret? Describe it. We have a pan/tilt mechanism. the turret can rotate around several times

[d.courtney]

we have a shooter which has 180 degrees of rotation

[lukevanoort]

We have a semi turret, it has about 70 degrees or rotation. However, it's sort of useless, since the drivetrain turns quicker and easier than the turret.

[Levin571]

we also have a turret that can turn 180 degrees... we call it the "Kaboomer"

[nuggetsyl]

yes it goes 300 degrees hopefully we will not need it

Yeah, our turret can make a 247 degrees arc, and has two chutes to accept balls. We use the turret to track the target and fire while moving. However, we can only pan. The trajectory and spin of the balls gives us a large range we can fire them over though.

[Elgin Clock]

When the limit switch kicks in and reverses it, it goes about 330 degrees and then back and repeats as needed till it finds the target.

[Biff]

Turret with slightly over 90 deg of rotation. Angle adjust in the pits. Three small Cims and 3ea 8" standard skyway kit wheels launch the balls. Tooth counter and software keep the cims at the same speed.

Our robot has a turret that can go fast enough to get us in trouble. We can also change elevation.

[Jeremiah Johnson]

We did... need I say more?


(If so... then we were a bit overweight.)

Why do you need to rotate around several times?

Why do you need a tilt mechanism?

My team doesn't have a turret. (we can however turn, which hopefully will suffice in place of one)

--Insert Random Sidenote--
I just thought I should point out that this poll shows how weighted Chiefdelphi or at least the technical discussion community is weighted toward the high end of FIRST. I know for a fact that far fewer than 50% of all teams will have a turret. About 50% could very well be the number that can shoot, maybe less. The percent of those that have a turret is probably closer to 10-15%. That should leave the number of teams with a turret at around 5% probably.

I can speak for us saying that we wanted to turn around multiple times as well for accuracy and shooting even more "on the fly" than we do.

Tilt is the ground to sky motion right? lol
If it is, As for tilt, it's not needed that much, but if your camera is locked in place for tilt you lose the target a few times on the floor (ie: going up the ramp, really close to the target, really far away.

We based ours on a set point we know or max shooting range is, and we're good to go, except for some of the instances mentioned above.

So far that is.. I don't know if a tilt is programmed in, and I just didn't see it.

We have a turret but we're probably not going to use it..

[Eldarion]

Ours can rotate -120° to 120° for 240° of total rotation.
Elevation control is accomplished by varying the speed of our cannon.
