Hello all
I'm from "moving camera" world with drones, gimbals, cablecams etc.

I already have cablecam system which can drive camera from point A to point B on same height.
My wish is to build system where camera can travel in 3D space (skycam, spidercam...).
I know these are very large and complicated systems for large cameras and large areas. For start I would like to build something which can carry light camera (up to 2kg with gimbal) and to cover areas like smaller sports halls.

What kind of motors, winches and drivers I can use for this purpose? My brother is automation engineer so he can help me with programing.

Thank you.
