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

Plan

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

Procedures

Using the materials which arrived from Amazon last week, I built my first servo-mallet prototype to test it out on a xylophone. 

Progress

I first tested my code on varying the mallet speed by changing the servo’s rotation degrees per second. A video can be found here

I followed up by testing out the system onto the actual xylophone. A video can be found here

Problems

After testing out the servo-mallet system on a xylophone, I realized that the size of the servos is currently too big to fit 30 of these systems and align it with all of the xylophone keys. For the upcoming weeks, I will need to think of a way to fit all 30 servo-mallet systems across my xylophone, whether it is using new servos, extending the xylophone frame, or modifying my mallet system.
