In basic terms, Tribophysics is the study of the friction, lubrication, and wear between materials in relative motion. In other words, what happens when the surface of one object slides up, against, or over the surface of another object. So what happens when your favourite robot slides the trombone? Some sweet, sweet sound, that's what! Show your love for both robots and the trombone by showing off this fine magnet! Collect 'em all!
