The AUVSI Foundation is a 501(c)(3) charitable organization that was established to support the educational initiatives of the Association for Unmanned Vehicle Systems International (AUVSI). The AUVSI Foundation focuses on the future of the robotics industry by developing programs that will attract and equip students for a career in this rapidly growing field. Through a variety of efforts, the AUVSI Foundation provides students with the opportunity to experience fun, hands-on robotics activities that promote STEM education (science, technology, engineering and math). At the K-12 level, the Foundation introduces students to the wide range of robotics programs available to them, fueling their imaginations while enhancing their education. As students’ skill levels advance, the AUVSI Foundation hosts robotics competitions that challenge students to apply their engineering skills in the development of autonomous ground, air and maritime vehicles. To date, the AUVSI Foundation has awarded nearly $1 million in prize money to participating schools since the competitions began in 1991.
