Well ive been working on this 4 axis motion controlled camera dolly in my spare
time for over a year now. Now that im 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, thats the best part in my opinion!
Im 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 bpy experience
would join me on this project!
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
- 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.
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.
Operates 200 ft away from the controlling computer.
Although this rig dose time lapse it also moves quite fast and
can certainly replace an actual camera operator in many situations!
Each axis of the rig is driven with timing belts allowing you to swap
different sized pulleys for better speed vers 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!
Its quite possible to build one of these for around 400 bux!
kits … shoot me an email at rylangrayston @gmail.com if you would like me to send you
a dolly kit (all parts included), I can make some up but ill have to charge around 900 per kit
to cover my expenses as I live very far away from my hacker space! Ether way I certainly dont mind
selling a few, I understand not everyone has access to a cnc router! and it would be great for the project
if I wasn’t the only one with one of these things!!
Futrue goals for the suzans dolly
- blender gui … so you dont have to operate it from the terminal
-code it to communicate with the L6470 stepper driver ( i will be doing this next!)
the L6470 driver will alow for much faster and smother operation and allow for the use
of bigger stepper motors two!
-add more axis and keyed lighting controls
-real time motion tracking
-home page for the project where people can get resources and offer to help out (any one want to help out with this?)
well I guess ill just end with a thank you to blender artists form and a few of the members on here( you know who you are)
that have helped me out with various little bpy quires of mine Thank there is no way i could have got this far without you
Also thankyou to all those that created blender, this is one program that I can honestly say has changed my hole life!!
