The Girls of Steel, FIRST Robotics Competition Team 3504, founded in 2010 at Carnegie Mellon's Field Robotics Center, has a team mission to empower everyone, especially women and girls, to believe they are capable of success in STEM. The principles of our team include: teamwork, communication, respect, integrity, inclusion, and safety. We teach mechanical and technical skills, programming and analytical thinking, as well as leadership, teamwork, and business skills. We also value a commitment to quality, ethical behavior, and respect for others. Through outreach we aim to educate young people in STEM using hands-on design and development of a robot.
