Mobiro the Robotic Violinist Robot #Robot - Concert violinists and music teachers the world over, be afraid. Be very afraid. Toyota’s ‘Mobiro’ is a 5 ft. tall robot with an uncanny ability to play the violin. And here’s the bad news: ‘Mobiro’ is only the latest in Toyota’s ensemble of musical robots that already includes a trumpeter, trombonist and several others. It uses its 17 computer controlled joints and agile fingers to hold the instrument and delicately sound out sweet airs.
