If you are doing a senior design project in engineering school, it takes some guts to make a robotic duplicate of the school’s president. He or she might be flattered, or completely offended. Us? We laughed out loud. Check out the video below. Spoiler: the nose/moustache wiggle at the end kills us every time.
The project uses a variety of parts including a plastic mask, an Erector set, and the obligatory Arduino with an MP3 shield. There are many articulated parts including eyes, nose, mouth, and wiggly moustache. The face uses RC servos, although [gtoombs] says he’d use stepper motors next time for smoother motion.
The mouth synchronizes to the audio, although this is hard coded, so it would take some work to make the face speak arbitrary speech. Still, it would be possible with a little work.
