An Austrian electrician has invented the world’s first tattooing robot.

Niki Passath, 25, unveiled his creation, which he calls Freddy, at a high-tech fair in Vienna.

He has been left with some permanent reminders of the project with some erratic early tattooing attempts.

Passath told that it was a hard job because “the only person I could test it on was myself which was painful but a good incentive to get it right as soon as possible.

“He’s an artist of course so he always decides what design the person is going to get, they can’t choose. But I haven’t had any complaints yet.”

Freddy’s computerized brain has a complicated program for creating the designs that are constantly being improved and redesigned before being etched forever and for free on the bodies of volunteers at the trade fair.

One volunteer said it wasn’t too painful at all.
