When Camille Beatty was 10 years old, she dismantled a TV remote and handed the parts to her surprised father, Robert. Next came a string of questions about the circuitry. “I got to a point in my life where electronics seemed magical, but I knew they weren’t,” says Camille, now 13. “So I started opening some up. I wanted to know what was inside and how they worked.” Robert hadn’t a clue, so he, Camille, and his other daughter, Genevieve, now 11, searched the Web to find out. The family used their newfound knowledge to build their first robot only weeks later.
