Her Majesty was introduced to robot Nao at Berlin's Technical University on the first full day of her state visit to Germany.
Lecturer Marco Luetzenberger, 35, instructed Nao: "Stand up!" when the 89-year-old monarch arrived. He then asked, "Where is the Queen?" and Nao turned to face her and Prince Philip - causing much amusement.
Mr Luetzenberger said: "What do we do when we see the Queen?" and the robot saluted. Afterwards, Mr Luetzenberger said: "We wanted him to bow but that's quite dangerous. We didn't want him to fall over the table." Click link for full post from EXCRESS.
