Just interested in how other people have their cameras set up...

Mounted on the turret with a tilt servo; using turret to pan.

The tilt servo only has two positions, near and far. :)

ours is mounted (poorly . . . one of the things well be fixing on our thursday) on our turret, with both the tilt and pan servos(the turret is only 320 deg so we left the pan servo on to "keep a beat on the light"

We used the pan/tilt assy in the kit but locked the pan axis in place. Tilt is controlled by our turret. There is a lexan wall protecting it

Pans with turret, no vertical adjustment.

Who needs a camera? We don't have one.

Camera on turret with both pan and tilt servos. We decided the rotator would not have enough angle of rotation to be an effective pan adjustment for the camera (our rotator only does 40-60 degrees, just enough to hopefully keep us pointing at the goal if we start getting pushed while shooting), plus the camera can search faster moving the pan servo rather than the rotator.

Our cameras are mounted one on either side of the turret mechanisim, both on pan/tilt servos. The turret itself pans and tilts.

looks sorta like this:


[[O]]---()______()---[[O]]

With the () being the rotating shooter motors, and the little [[O]] things being the cameras mounted on the pan/tilt servos.

You have two cameras? How did you wire them through one port?

I didn't. I have a custom circuit board with three rs232 level serial ports, two of which connect to the two cameras and one of which connects to the program port on the PIC, not the TTL level port.

Binocular vision could also be accomplished by connecting one camera to the program port and one to the TTL port, and then messing with Kevin's camera driver code to use the cameras on both ports. My way was just easier, 'cause I'm lazy.

Also note: the cameras don't really need to be powered by the 7.2 volt power supply on the PIC board. If you're not powering the servos off the camera board, 5v will do just fine in powering the camera itself, it says in the "Big Binder of the Camera" that power goes through a 5v regulator. So just hook up the camera to a digital inout or whatever for power, and you won't have to deal with backup battery foolishness, because that silly thing was being drained far too quickly by our two camera setup.

Our is mounted completely reversed (y pan and backwards, x is tilt and backwards) because my crew didn't listen whenever the built the camera casing and it has to be out of the way of the shooter. The camera itself is mounted on our Shooter so the robot pans and the shooter tilts. Probably won't end up using it though depending on how much practice time I get.

Our camera is mounted in a piece of 2x2 aluminum box tube, that is bolted to the turret. The camera itself is epoxied to the board it is plugged in to, using two wood blocks, and the wires are soldered to the board so no connectors can work out due to vibration. The camera lens looks through a hole in the box tube.

The camera pans with the turret using feedback to keep the turret locked on the target. The height of the target is used to control the wheel speed so that a fixed 45 degree shooter can hit the target from different ranges.

ours was mounted underneath the turret to prevent any from ball hitting it.

Ours is mounted directly in front of our shooter wheel, with lexan protection of course, and the balls go over it. We just used the top part of the pan/tilt assembly, with only the tilt servo being used.

Mounted on turret (rotation), no vertical movement capabilities.

mounted on the camera mounting thing that was in the KOP.
it can pan and tilt, and is used in determining distance and angle away from the goal.

Our camera is on a very advanced custom mount, a shelf in our shop.

(Sorry, I couldn't resist) :D

We don't have a turret, so the camera got bolted straight onto the robot, right underneath the shooter. We might have benefited a little from having the pan/tilt assembly, but we were coming in too close to weight, so the driver just has to get it close to lined up and then hit the center buttons.

The camera is mounted on the turret, using the turret to pan.
The camera tilt is fixed at a slight upward angle. The vertical position of the target in the view is used to calculate the angle to aim the shooter.
