Hi. I am working on a project that requires moving a small camera on a platform in a linear fashion. I have a rectangular board and this camera need to move from one end to the other controlled by an arduino. I don't even know how to begin to approach this problem. I am thinking of something like a rail that can be controlled by a micro controller. Can someone please give me some pointers? Thanks!!!
One option would be to use the Arduino to control a motor that rotates a screwed rod so that a nut (with the platform attached) moves along the rod.
You could also look at the toothed belt systems that are used in 3D printers.
belt drive and stepper motor is a common approach - belt drive reduces vibration and allows quick movement when needed (like resetting to the start).
Leadscrew drives are slow unless you have long-pitch or multi-start leadscrew and a performance stepper driven at high voltage. CNC machines use leadscrews because they need the stiffness and high forces.
To move a camera, people often use linear slides with step motors. This precision kit from OpenBuilds is a pretty good bargain.
