World-famous Italian tenor Andrea Bocelli has sung at a classical concert conducted by a robot.
The event opened the International Robotics Festival in Pisa, Tuscany, which runs until September 13.
Bocelli sang the famous La donna e mobile (The lady is fickle) from Giuseppe Verdi's opera Rigoletto.
The Swiss-made robot YuMi was programmed to imitate the movements of the director of the Lucca Philarmonic Orchestra Andrea Colombini, Francesco Ceccarelli, a festival spokesman told dpa.
The robot would not be able to improvise and lead musicians on its own, Ceccarelli said.
"Men need robots, but robots also need men," he said.
There have been other examples of robot-conducted orchestra in the past. The first time was in 2008, when a Japanese-designed machine led the Detroit Symphony Orchestra.
