Robots give Greece's postal service speed boost

Athens: There's a new addition to Greece's postal service: a fleet of yellow robots sorting through the mail.

Fifty-five small, four-wheeled autonomous mobile robots -- or AMR's -- powered by artificial intelligence, glide around Hellenic Post's sorting centre in Athens, speeding up an often arduous process.

They scan the postal code, weigh the package and, directed by sensors, empty it into the corresponding mail sacks set up around a platform.
