This Winter Olympics, 12 types of robots at your service

Robots swarming in 2018 Winter Olympics in PyeongChang to serve visitors, athletes and delegates with food, drinks and directions show South Korea's automaton way of hosting the Winter Olympic Games for the first time, with the country deciding to deploy at least 12 kinds of robots presented here in a list below: Korea Advanced Institute of Science and Technology's (Kaist's) Hubo robot is the first unit deployed by the country for the event. In December last year, the humanoid carried the Olympic torch, clearing a path for itself through a makeshift wall, set up as an obstacle, to hand the torch to a Kaist professor. In 2015, the humanoid had won Kaist a prize of $2 million by not falling off in order to complete simple tasks like opening doors. The robot also features a Bumble Bee-like ability to switch back and forth from a walking biped to a wheeled machine. The second robot deployment FX-2, that carried the professor who received the Olympic torch from the humanoid, is an eight-foot-tall human-operated robot weighing more than 600 pounds with a price tag close to $1 million.
