Avery W. Fiore entered the world of robotics competition aged 10. He has led teams and won numerous awards in FIRST® LEGO® League, VEX® IQ Competition, VEX® Robotics Competition and FIRST® Robotics Competition. In 2020, when the world came to a standstill due to COVID-19, he picked up CAD via a single Youtube video. With a bit of imagination, he designed a fully functioning robot that went on to win the Excellence Award at VEX Worlds 2021. Always passionate about sharing his love for robotics, he wrote this handbook to complement CAD classes he conducts for junior members. Avery was the FIRST® Robotics Competition Captain for Team 4817 at the Singapore American School from 2022 to 2024. He is currently fulfilling his national service obligation in the Singapore Armed Forces.
