🇸🇪 Three schoolgirls at a runestone on Ströbo meadow at Herrstaberg, Sweden. The innoscription says: “Vibern raised this stone in memory of Solva, his brother.” Photo from the 1880s. There are about 2,500 rune stones in Sweden, most of them from the 11th century A.D.

The ballet dancing robot

LEONARDO (or LEg ON Aerial Robotic DrOne) is the creation of researchers at California Center for Autonomous Systems and Technologies, who came up with the idea of stabilizing a robot on two, rather clumsy legs.

To do this, they applied drone motors that keep the robot balanced and help it move, just like birds do when moving between walking and flying, using their wings. This feature opens up new opportunities, including spinning around like a real ballerina.
