Hey all... I figured this was a good place to start.
I'm looking for someone who can take on a project for my company, to
design a very accurate PTZ mount for a small camera. The mount will
need to have a resolution of around 100,000 steps (0.0036 degrees per
step), and high accuracy positioning (repeatably it should go to the
same exact spot when it's told to via serial/network communication
interface). The camera weight will be around 1lb, so it doesn't have
to be too heavy duty. It also needs to maintain a minimum speed of 60
deg/s for movement (ideal is 100-120 deg/s).
Anyone interested in a project like this? I can provide more details
to those interested in the project. It needs to be developed as a low
cost mount, I can elaborate on what low cost means in an email.
Is, say, $40,000 in moderate production quantities "low cost"?
And what would you bolt it to? A few cubic yards of nice reinforced
concrete might be a start. Slewing 11 pounds at 20 RPM to 13
arc-seconds accuracy will get interesting; bedrock footings, maybe.

1lb, not 11lb.
