Last year at CES, LG introduced a bunch of new robots because, as near as we could tell, LG figured that robots were cool so they'd better make some robots or something. The most photogenic (and smallest) was Hub, which bore a striking resemblance to Jibo, but we also met two burly service robots designed to work at airports. For CES 2018, LG is adding three more robots to the CLOi (that's pronounced KLOH-ee, obviously) family. New this year are the Serving Robot, Porter Robot, and Shopping Cart Robot, "developed for commercial use at hotels, airports, and supermarkets," and it's definitely not a coincidence that they're just in time for the 2018 Winter Olympics in South Korea, where LG is also based. The purpose of the Serving Robot is to deliver meals and drinks to guests and customers at hotels and airport lounges quickly and efficiently. The robot can deliver food or refreshments around the clock and with its built-in sliding tray, present the tray to the customer for easy removal.
