If the marbles are light enough and you have an appropriate air source:

#1 blow air across top of tube slightly larger than the marble
#2 use bouornulli (sp?) fource to lift marble
#3 when marble reaches top air blasts it into some sort of receiver

If you have a vacuum source that will lift the marble 2 meters up a clear
tube that is slightly larger than the marble.......

#1 detect a marble in position
#2 suck it up
#3 spit it out
