In the space of four years, Robertson has gone from starting out in karting to racing in the all-female series. Competing in her second year in the British Kart Championships in 2024, she achieved multiple top-10 finishes and was the only female to compete in the Senior Rotax class.
Selected for a factory drive with Radical in 2025, she beat out more than 50 other young British drivers and went on to claim third in the Radical Cup UK Standings. Robertson was one of 18 drivers chosen for the inaugural F1 ACADEMY Rookie Test last September, achieving the fifth-fastest time at the Circuito de Navarra.
