"Hakuna matata" may very well be the only Swahili phrase that many people outside of East Africa have ever heard (thanks, Lion King), but a 4-foot-tall humanoid robot named Pepper is working to change that. The National Museum of African Art in Washington, D.C.--part of the Smithsonian Institution's network--is using Pepper to explain the meaning of Swahili words and phrases that appear in its artworks. The Smithsonian says it's the first museum complex in the world to use this particular robot, which was developed by SoftBank Robotics in 2014, made available to Japanese consumers in 2015, and later released to a wider market. Considered to be the world's first robot capable of reading emotions, Pepper is multi-talented. He has already found a home in several different Smithsonian sites, where he interacts with visitors, answers questions, plays games, tells stories, and even dances.
