Here's a Camera rig controlled by Blender 3D (see video below). Yep, the same Blender 3D Modeling App, that was used to make this Great Animated Movie (see below)...

Working blender motion control camera rig! - Suzans Dolly

suzanns dolly.blend ... down load this and check it out ---->r72 suzanns dolly.blend

Well I've been working on this 4 axis motion controlled camera dolly in my spare
time for over a year now. Now that I'm actually getting some usable footage
out of it i figure its a good time to share it with everyone.

Here is a little video demoing some of what the rig can do
Watch closely for the change in focus between the red candle and the white one!
I love this thing! Hopefully Ill have time to post another video detailing
how to use it, that's the best part in my opinion!

I'm calling it "Suzanns Dolly"
It is by no means done. There are still some glitches and it really needs a blender GUI.
This form post also a cry for help! being that this is approx the 5 th python script iv ever
done and certainly the first worth sharing, I am in way over my head!
So coders please dish out the constructive criticism and lots of it but
also with the understanding that I may not have the skills to implement your
suggestions! and of course i would love it if some people with more by experience
would join me on this project!

Features:
4 Axis Camera Rig:
dolly, pan, tilt and focus/zoom

Time Lapse Mode:
-any delay in 1 second increments
-take pic while the rig is completely still
-and or take motion blur pics the shutter will be open while the rig moves

Animated Control:
- a key framed/animated model of the camera rig
in blender sends its animated motion to the real camera rig.
The real camera rig dose whatever the animated model dose.

Manual Control:
animated control is nice but far more useful
is Manual control. I recommend using a wireless key board with a neck
strap! the dolly can be moved around with the key board its positions
can be inserted at different times. This is very handy and intuitive!
It is very much like driving a remote control car! This is also the
way that professional camera rigs like Milo are key framed.

Blue-Tooth Wireless:
Operates 200 ft away from the controlling computer.

Fast!:
Although this rig dose time lapse it also moves quite fast and
can certainly replace an actual camera operator in many situations!

Belt Driven:
Each axis of the rig is driven with timing belts allowing you to swap
different sized pulleys for better speed verses torque and accuracy ratio

Adjustable Base Plate:
adjustable base plate allowing you to balance any dlsr camera
and a unique belt system that fits any lens enabling you to use
the 4th axis for zoom focus or even aperture!

Cheap:
Its quite possible to build one of these for around 400 bux!
