During the NOVUS 2015 project, I had the opportunity to work with an interdisciplinary team on the development of a Brain-Computer Interface. This consisted in controlling a 3D printed arm via servo motors to play the piano. The team was made up of students from Systems Engineering, Mechatronics and Music Production Engineering. We published our paper here (spanish).
NOTE: The robotic arm could not yet move horizontally across the keyboard. Finger movement is achieved via facial gestures. We encourage others to implement more control gestures and make the interface more expressive.
