ROBOT BUS . . .

Giant robot bus pushes for London Olympic Glory...

The creation, called London Booster, is the work of Czech artist David Cerny. The Czech Olympic team has set up this double-decker bus from 1957 outside its London HQ. Except now the bus has giant mechanical arms for doing push-ups.

An electrical motor powers the giant robotic arms which lift the bus up and down, each motion accompanied by the sound of a grunt or physical exertion. When it's not doing push-ups, it sits there, panting and breathing.
