The "Fill-O-Matic" is
used to fill old ink cartridges. All the operator needs to do is
tell it how many cartridges they inserted, and they need to insure they
have inserted the cartridges properly.
The "Fill-O-Matic" has 4 degrees of freedom. It can
move horizontally in 2 directions using a motor belt and pulley, and
one with a print mech. It also moves vertically using a print
mech. Finally, it moves the plunger of a syringe up and down
using a modified mech of an old disk drive. Once told how many
cartridges there are to be filled, the "Fill-O-Matic" fills its syringe at the well
station. Then it moves to the first slot, and fills that
cartridge. Then it proceeds back to the well to refill, and
continues until all of the cartridges are filled.
