Girl Scouts are learning valuable life skills as they discover how to build and program robots. Under the guidance of mentors, girls experiment with new techniques and learn from the outcomes. Girl Scouts who participate in robotics teams discover their ability to succeed with technology while developing strong teamwork skills. We have robotics teams for all grade levels!
