Teams of students from five Las Vegas area high schools who have been challenged to invent robots that can throw a Frisbee will who off their creations at the PACK EXPO trade being held at the Las Vegas Convention Center on September 23 to 25. For the second consecutive year, the robotics competition is held annually in conjunction with the trade show, according to a news release. This year’s theme was “Ultimate Ascent” and the students’ robots will compete to see which one can throw the Frisbee most accurately. The PACK EXPO is one of the world’s largest packaging and processing annual trade shows.
