A project log for Bot-thoven: A Robot Musician

Creating a robot that will be able to perform on a xylophone with musical expression - such as dynamics and articulation.

This week, I will continue printing more copies of the prototype of the servo-mallet system.


I will continue 3D printing out more copies of the stand prototype and building more servo-mallet systems. This will allow me to test my code for varying servo speeds (for dynamics when hitting the xylophone key) and see if it will work when the microcontroller has to control several servos at once.


Above is an image from the CURA 3D printing software detailing the layout of my current print. The print is currently in progress (image below) and will be finished by Thursday evening.

I have also placed my order for the 16-Channel 12-bit PWM/Servo Driver from Adafruit this week, which will allow me to test if the shield is compatible with my microcontroller. 


Once the shield from Adafruit arrives, I will need to take all the servo-mallet systems that I made this week and test the shield to make sure it functions as intended: allowing a single microcontroller to control multiple servos at once.
