Hi all !
I am a young french film-maker, and I used to build the machinery I use to shoot clips, ads, or short films.
I want make a 3 axis motorized camera head. I choose stepper motors to be able to control them by pc (or ideally mac) for motion control or manually by joystick.
Later I want to add to this a motorized track dolly equipped if possible of a pneumatic or other arm to make rise the head.
To have a clearer idea of the project, here is which is going to look like the head:
The system with dolly:
And here is what I have for working base :
I must be able to controler 5 engines by computer, and be able to make moves sequences that i'll can reproduce at infinity and by joystick and potentiometers for the manual control. Every command has to be proportional... It is really important that I can manage the speed of engines.
It is there that I am lost... Which control card to take? Which joystick? Which card for potentiometers?
Besides the use on track dolly, I also have a crane on which I am going to put the camerahead , I also think of puting up this head on vehicles to film pursuit sequences, how gyrostabilize the system?
Is my choice of stepper motors is right ?
