The Queen looked pretty amused when she came face-to-face with a robot in Germany – and it saluted her.

Her Maj has received royal salutes from all kinds of people – usually servicemen and women – but now she can add a robot called Nao to her list.

Nao’s designers had planned for him to bow for Liz when she visited the Berlin University of Technology but they were a bit worried their creation might topple over. Now that would have made an even better photo op.

Lecturer Marco Luetzenberger, 35, from Berlin, told Nao to “stand up” when the Queen walked over to it.

He then said “Where’s the Queen?” and Nao turned around to face her as she and the Duke of Edinburgh beamed with amusement.

Marco then asked “What do we do when we see the Queen?”, at which point the robot did what looked like a wave or salute.

“Can you salute the Queen again?” he said, and the robot repeated the gesture.

Afterwards, Marco said: “We actually wanted him to bow but that’s quite difficult and dangerous and we didn’t want him to fall over the table.”

Earlier in the visit Philip chuckled while the Queen put on a poker face worthy of a secret agent when they watched a re-run of her encounter with James Bond at the London Olympics.

The 89-year-old monarch initially smiled when the famous footage of her meeting with 007 actor Daniel Craig was shown during a lecture attended by hundreds of students.

But she then sat impassively, watching as she appeared to parachute into the Olympic Stadium in 2012 to applause from the audience.

The screening was part of the Queen’s Lecture, an annual talk in Germany, now in its 50th year.
