Motors, gear boxes and pulleys, OH MY!
We are making a time lapse dolley with an arduino. We need to move a 5 lb camera across a metal frame smoothly to produce a great shot. How can we do this?

How would I program this on the arduino? Any ideas for the actual coding?

Its undecided so far but it has to be portable. Therefore, we were thinking battery powered

the dolly works by a motor pulley system moving a camera back and forth on a track thats approximately one yard long. We need to be able to control it to the second with a vary broad range. For example the camera may need to move across the track in 30 seconds or it could need to move across the track in three hours. we have played around with the idea of a step motor but I don't know if it can give us enough control.

do you know of any good sites to find one of these?

will it connect to any step motor or do we need a specific kind
