The analogy from basketball is kinda like offensive charging, only "with intent".

Our regional judge said if you are "playing the game" which is to say, attempting to retrieve and score baskets, then no technical. So there is the human judgement factor. Certainly if you have no ball to shoot, and no ball nearby to retrieve, just hitting the other guy to get a 3 point foul is not wise. You leave too much room for the judge to nail you with the technical.

Talk to your regional head judge and get their direct feedback, especially after they get their final directions from HQ. And buy them coffee the morning of your event.

Our shooter's top is around 50" as well.

FIRST Team 1296 is at 52" - also seems safe to me

Ditto for us (more like 26 probably). It works out for blocking because you want to shoot at something close to 60 degrees anyway, which puts the shot to 60 inches above the ground within 6 inches of your bumper, and we figured no one would want to get that close (if they do, we're in the key and have every right to touch them when wrestling for position). It keeps the CG low, ball storage smaller (exactly 3 balls), the robot lighter, and things a bit simpler.

That's not neccesarily true. You could have a tower that's low to the ground and be right up against a taller robot, and all you have to do is just change the angle. The thing you need to take into consideration with the height of the tower is how that affects the center of gravity. You need to make sure its low enough for traversing the bump and/or bridge (if you're doing either). Low cg's will come in especially handy when trying to balance. I'd say a heigh of 30 or 40 is good. That's what we've got.

Re: Turret/Tower Height

Hey teams. just wondering where you find the sweet spot as far as the height of your shooter tower. First, Are you using a spinning turret or a tower with a spinning shooter?we have a spinnining robot. How many degrees does it turn, if it does at all?it can turn 360 Finally, how tall are you guys making your tower?we will not have a "tower" I figure it doesnt need to be more than a foot of tower space, but then again maybe some people are storing balls in the tower. What do you guys think?i think your robot will fall over the first time you shoot a ball.

why are you so obsessed with spinning towers?

Re: Turret/Tower Height

We're avoiding a turret because we'd heard that during the 2006 competition, drivers would get confused by the driving chassis and turret turning independently (using tracking systems). It's also more complication that is not necessarily needed.

I think the main danger with towers is that they can whip around on the bridge, when crossing the barrier, or when your robot is hit by other robots (and can then break off without a significant amount of bracing). They also alter the center of gravity quite a lot. While you may not fall over when shooting, a robot with a tower possibly may when crossing over the barrier (especially when hit by another robot) or more likely, when crossing the bridge.

Our shooter is about 28-30in high right now. We've configured the shooter so that it can't be blocked by other robots. It is still vulnerable to being rammed.

We're aiming to be able to shoot from several places on the field.

Re: Turret/Tower Height

Our shooter is a one wheel design with the axle mounted at 36 inches high. We're using a small amount of vertical space plus the angled space from the front of the bot to the back (Where our shooter is located) to store the balls.

Doesnt most teams have one student driving the robot and the other working the controls?
