A FIRST LEGO league team (#144) that meets at the Carnegie Free Library of Swissvale on Saturday mornings during the fall and spring seasons. Meetings are from 9:30am to 12:30pm (including a snack break). One of the tenets of Andrew Carnegie libraries is that they offer free service to the community. In keeping with that important tenet, there is no cost to participate on the RoboCatz team.


For the 2022 season, you will need to enroll your child onto the team through a web-based system.
