Will Cogley, known for his awesome animatronics, has created a robotic mouth that’s already a work of art and could form the basis of something even more amazing. The device features an array of servo mechanisms to actuate its jaw, forceps, cheeks, and a tongue….
Frank Piesik recently designed a robotic three-stringed instrument for his friend, Gregor, that features a unique sound and mechanical arrangement. Notes are selected by an array of 12 servos — four for each string — which pull down using a loop mechanism. The aptly named…
