Designing a Servo Motor Based Mallet System to Generate Musical Expression in Instrument Playing Robots

Plan

This week, I will test the prototype for the servo-mallet system I will be using. 

Procedures

Using the servo-mallet system I built last week,  I will continue testing out the prototype to find areas to fix and improve on. 

Progress

Below is an image of the servo-mallet system I have built as a first prototype. Currently, David and I are testing out the servo to move at different speeds, in order to achieve hitting the xylophone key with varying dynamics (loudness). 


In terms of fitting all 30 servos across the xylophone, I have decided to test the method of staggering mallet length. This week, I have built copies of the servo-mallet prototype. With these additional mallets, I will be able to physically test this method next week to see if it will work. If not, I will look into other options such as building a new, wider frame for the xylophone keys or using a smaller servo as a replacement. 

Problems

I will need to test the staggering mallet length method to see if I will be able to resolve my problem regarding how my servos are currently too big to fit 30 of these systems across all of the xylophone keys.
