This project is an exploration of interaction, mechanics, and animatronics, combining technology and a handmade puppet.

Using Processing and Arduino, the computer keyboardmoves two independent motors, one of them control the horizontal movement of the hands, and the other one control the vertical movement, also every key emits a prerecorded sound. Therefore, the keyboard on the computer represents a real piano, and when the user plays the keyboard on the computer will make the cat to play the piano.

The mechanism is made using two servo motors and some pieces of Lego.
