Box, run, crash: China’s humanoid robot games show advances and limitations

Beijing is keen to showcase country's prowess in robotics, say observers - but some are sceptical about real-world use

A quick left hook, a front kick to the chest, a few criss-cross jabs, and the crowd cheers. But it is not kickboxing prowess that concludes the match. It is an attempted roundhouse kick that squarely misses its target, sending the kickboxer from a top university team tumbling to the floor.

While traditional kickboxing comes with the risk of blood, sweat and serious head injuries, the competitors in Friday's match at the inaugural World Humanoid Robot Games in Beijing faced a different set of challenges. Balance, battery life and a sense of philosophical purpose being among them.
