Robot that plays a Violin

Ro-Bow is a robot, a kinetic sculpture, that plays a standard full size violin.   Watch the video…

Ro-Bow by Seth Goldstein, is a horizontally orientated violin, that rotates underneath a reciprocating violin bow while four mechanical fingers ‘are moved to make contact, as appropriate, with the (highest) bowed string.’

Computer control was provided by Randall Pursley. When music is played on an electronic keyboard, a MIDI file is generated which is edited, and then used as the input to the violin computer. This computer generates numbers to control the electronics, powering the various motors to perform the prescribed motions which enable the violin to play the same notes as were originally played on the keyboard.
