Beijing: Step by mechanical step, dozens of humanoid robots took to the streets of Beijing early Saturday, joining thousands of their flesh-and-blood counterparts in a world-first half marathon showcasing China's drive to lead the global race in cutting-edge technology.

The 21-kilometre (13-mile) event held in the Chinese capital's E-Town -- a state-backed hub for high-tech manufacturing -- is billed as a groundbreaking effort to test the limits of bipedal robots in real-world conditions.

At the crack of the starter's gun, and as a Chinese pop song "I Believe" blared out from loudspeakers on repeat, the robots queued up one by one and took their first tentative steps.

Curious human runners lined up on their side of the road and waited patiently with mobile phones at the ready to shoot each machine as they prepared to depart.
