7. Conclusion/Future Work

In conclusion, our device worked fairly well. While not perfect, it is evident a rhythm is being played and the keys are being struck according to design. Some areas for future improvement would include regulating the speed of rotation and hence tempo, using a quieter motor, and adding either more fingers or attaching it to a gantry in order to play more notes in a song. In addition we would like to invest in a motor with higher torque at lower rpms to overcome the force required to push down the piano keys as the servo failed to rotate if the angular velocity was too low.
