Unmanned convenience stores, vending machines, mobile payment...thanks to the latest technology, shopping has become even more effortless.

But shopping experience will go further than that: an eye-catching robot in Xi'an, Northwest China's Shaanxi province, has hit the streets selling drinks and ice creams.

Powered by 4G networking and artificial intelligence, the human-shaped robot, Mr Doer, offers ice creams and drinks on its own. The robot can also recite adapted poems or even dance to attract customers.
