Monta Vista Robotics (Team 115) recently made a FRC team manual called FIRST Aid Kit. This manual gives helpful advice about mechanical, electrical, media, documentation, finance, public relations, and competitions. It also explains our team structure and shows how we have sustained our team for 15 years. It is available on our team's website:
