Robot lends a hand to speed up mosaic artwork production
You can hear the whirring of the robotic arm as you enter the office. They call it Arty, and it works nonstop all day, picking and placing colorful, smooth tiles into 12-by-12-inch squares. A worker stands behind Arty and feeds the tiles into the machine. Then he picks up each square when it's done to shake all the tiles into place.
