We flipped on the power switch for our robot named Security. Then a low rumble erupted from somewhere in the room. The song Mr. Roboto began to play and the robot danced, moving back and forth, spinning and turning, playing its lights–all to the music. It was hilarious! We learned how to change the robot’s software so that I could control the pattern of the robot’s dance. I made the dance longer, more complicated, and even more fun than it was before!
A lot of our robots now talk, play sound effects, or play music, including Security, Roamer, and Mechatron. They have different ways of talking. Roamer uses a text-to-speech chip that my Uncle Chris helped solder into place, and the others use a tiny sound board that reads MP3 files from a micro-SD card. Most of the talking robots say “Roger, roger” because we want them to be a bit like the Battle Droids in Star Wars. It is so much fun to make them say things!
