In a national innovation contest, Princeton High School students have come up with an AI-powered robot designed to help people learn Mam, a Mayan language that’s in danger of disappearing. The school was named as one of three winners in Samsung’s national “Solve for Tomorrow” competition.

Mam, which is spoken by a half-million people indigenous to Guatemala, is spoken by several students who attend Princeton High School. And to help preserve the endangered language, students designed and built a stuffed animal robot named Che’w that can speak and even converse in Mam.

“When I call my grandma in Guatemala, she only speaks Mam,” said Mayda Jiguan, one of the students on the winning Princeton team. “She feels really happy that I’m able to share my culture with a lot of people,”

Schools participating in the competition had to pitch their ideas to a panel of judges in Washington, D.C. and winners received $100,000 for their schools. The Princeton students are seeking a patent for Che’w, with a version possibly available for sale as soon as this summer.
