Facebook of Revelations: Robots (2008)

A5 and A6 are robots whose new function is to sort screws in the same assembly line within a factory. As A5 and A6 begin to work together, they find that they both have the same priority which is something else besides sorting screws and which has not been programmed into their systems. As such, their work sorting screws begins to suffer, which is noticed by their supervisor and the robotics technician. A5's work also is affected by another robot. But after the end of the day, the priorities of this day may becomes a lost memory.
