New Scientist: An industrial robot from the 1970s made its stage debut last month at the Southbank Centre in London in a production called Sans Objet. In the production, two acrobats interact with the robot on stage, while an operator controls it from backstage. The piece is a power struggle between man and machine where boundaries between the two become blurred: At times, the robot becomes humanized and the people appear robotic. Sandrine Ceurstemont reviews the unusual performance for New Scientist.
