Mechanism to move things around

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.

…R

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.

Ananatha,
