There were no fireworks to dazzle the crowd lining the streets of Alexandria to celebrate Cleopatra’s triumphant return to the city in 47BC. Rather, there was a four-and-a-half-metre-tall robotic effigy of the queen, which squirted milk from mechanical bosoms on to the heads of onlookers. Cleopatra, so the figure was meant to symbolise, was a mother to her people.
It turns out that robots go back a long way. At the “Robots” exhibition now on at the Science Museum in London, a clockwork monk from 1560 walks across a table while raising a rosary and crucifix, its lips murmuring in devotion. It is just one of more than 100 exhibits, drawn from humankind’s half-millennium-long obsession with creating mechanical tools to serve us.
