[Solved] Pan/Tilt with axes consistent with the dome radius?

[Kale]

I purchased a pan/tilt camera platform and I found out that the centre of the pan and tilt axes are not aligned. In other words, the camera lens will not point perpendicular to the dome in all directions.

I would appreciate advice on platforms that are able to point the camera perpendicular to the dome in all directions.

Hi Kale,

I hear you.

I'm working on a tilt-only system for mine that will work with a Raspberry Pi camera. The actuator is the same micro servo listed in yours, but it's not integrated into the mount, so it can pivot more 'tightly' if you know what I mean. And since I'm custom designing it I can pick the radius of the pivot. I plan to have it work inside about a 3" diameter dome. The parts will be 3d printed and the actuator arm and pivot points will be (somewhat) adjustable by picking different holes so it should scale up and down a little bit.

Sorry, no help on the pan. The Raspberry Pi cam is on a ribbon cable and I don't think that will last long if I try to have it pan too, also I figure I should be able to turn the ROV pretty easily for looking left/right.

Once I get it ironed out I'll let you know.

Ok, my dome is 150mm (about 6"). I don't think that there will be much trouble to get a proper pan/tilt platform. I just want to check here before I scan the web. Must be cool to be able to 3d print your parts.

Looking forward to see the results.

Ah, very cool. Looks perfect, and you can't beat the price.

I found out that this piece was way to big of my ROV.
