Return To The Wire


PianoBot, created by a team of Olin students for Principles of Engineering, is an autonomous system that takes sheet music or MIDI sound file input and uses that to play the song using a series of hand-inspired actuators to depress the keys.

The team designed and fabricated a customized stand to hold 36 servos and mechanical fingers in place over the centers of the keys.

In addition, an Arduino Mega was used to interface with 36 servos to play three octaves of keys, via a carefully designed voltage regulator circuit.
