We are five students from the Franklin W. Olin College of Engineering, with a variety of majors and backgrounds, who decided to build a piano playing machine for our Principles of Engineering project. It's been a great opportunity to learn some new skills, and see our product develop over time.
Our objectives for this project were to create a piano playing robot that could play a simple song as well as a beginner. Our minimum viable product was a one finger bot that could play by sliding from note to note along a gantry, with a hard coded basic song. This would be controlled by a stepper motor and a servo motor. Because most members of our team had minimal prior experience working with mechanical, electrical, and computational components, our goals as a group were to develop basic skills in those areas, communicate well, and create a visually pleasing product with motor integration.
