Fall 2013 Don't Fret About it

Team Members: Matt Latour, Clinton Peterson, Jian Jin

Introduction:

The goal of our robot is to actuate the fretting of a guitar string on a homemade fretboard to play the surf-rock classic "Misirlou" by Dick Dale. The design features a set of riveted aluminum angles actuated by a camshaft. The camshaft is coupled to a motor while the second motor drives the pickwheel and drumsticks.

The final assembly features a custom breadboard circuit design controlled by an arduino microcontroller. The arduino code forces the camshaft motor to actuate the aluminum fretting to play each different note. The device contains a switch for guitar fretting only (camshaft motor is on, pickwheel/drum motor is off) and a switch for drums/pickwheel only (camshaft motor is off, pickwheel/drum motor is on).

The mechanism underwent two significant prototype milestones before the final assembly was built. The first prototype featured a steel-cable-actuated fretboard with camshafts hitting clothespin "paddles" attached to the cables. The second prototype made significant improvements by scrapping the paddle design and replacing it with a simpler aluminum lever design. The final prototype added motors and a radical paint job.
