Frequent flyer and blogger Max Prosperi tweeted a video of a toothpaste-delivering robot he encountered while staying in a Miami hotel on June 24.The video shows a cylindrical robot standing before a man, presumably Prosperi, who removes toothpaste and a toothbrush from an opening on its top before following instructions on a touchscreen that then sends the robot on its way.Prosperi shared an article about the robot, called it Botlr, in which he explained that it relies on a map of the hotel, which is stored digitally within, to maneuver through the building.A longer version of the video is included below.
