I need to move a little box along a curved rail. I was thinking to the rail as a cilindrical curved one (like a spring, to clarify)
I would avoid sistems like this
I was wondering about something like a "quite-affordable-priced-linear-motor-which-could-follows-curved-path". Does exist something like this or am I talking sci-fi?
Hydroponics growers use motorized hangers that run on rails to move their lights around their.. uhh.. tomato plants. You might be able to adapt an off the shelf system.
