Robots improving the PyeongChang Winter Games

Robots at the Winter Games in PyeongChang, South Korea are said to be helping the Games become more vivid and convenient.

Projector robots are offering real-time video for weather information and event schedules for the day. Robots are also being used to continually clean the floors in event locations, cleaning an area of 900 square meters in an hour. So-called "fancy carp" and "sea beam" robot fish are also on display, swimming 5 meters below the surface of the water. They are able to go non-stop for 30 hours on a 5-hour charge.
