Hi,
What I have understand from your statement and your you-tube video link that you want a control over your camera in Z-Axis and Y-axis, and you want to have this control using your PC.
In my view your project shall have 02 Parts.
Part-01
One is a micro-controller based circuit use to control the two motors in order to move your camera in Z and X Axes. The same controller shall communicate with the PC over RS232.
PArt-02
This shall contain a software which communicate with the controller as per your commands on your PC screen
I think I can easily take this project and Part-01 shall be developed using PIC controller while Part-02 shall be industry standard Lab-windows software with high end graphics.
Following shall be the milestones
01. Specification requirement for Par-01
02. Schematics using altium
03. Simulation using proteus of circuit and software
04. Software delivery
05. Specification requirement for Part-02
06. Software delivery
About my self , I have 14 year experience in electronics, micro-controllers and system designing,
