you should have the option to select item not only by the x, y- coordinates, but also the z coordinate. to get the only bag of potato chips you want that is in the very last slot...-- sin, Jul 21 2003 [Mr Burns]: Huh?-- bristolz, Jul 21 2003 I like this. It would also eliminate the problem of the first slot being empty due to a malfunction. I've wondered how much money vending machine companies miss out on when a row is nearly full and stays that way because the first buyer got a bonus. Not sure how you'd implement this. I guess a totally new type of machine. Seems like there'd be some wasted space to make room for the additional picking mechanism, but, + anyway.-- half, Jul 21 2003 What happens to the products on the rack that are in front of the one you want?-- waugsqueke, Jul 21 2003 A hole in the top of the machine could let you redeposit the unwanted product. It would work on the honor system.-- phundug, Jul 21 2003 vendors dispense from the front and are generally filled from the back, thus, in always vending the front pack/bar/can, you get the oldest product in the machine. This is the only way that the vendor filler can guarantee effective stock rotation, which is good for us all. sorry, I must fish you.-- jonthegeologist, Jul 21 2003 as opposed to humans which are filled from the front and dispense from the back-- DeathNinja, Jul 21 2003 naughty death.-- po, Jul 21 2003 random, halfbakery
