Chinese inventor Tao Xiangli controls his self-made humanoid robot (from behind) to move towards a door during an interview with Reuters at his house located in an old residential area in Beijing. The self-taught Chinese inventor built the machine, named The King of Innovation, out of scrap metal and electronic wires that he bought second-hand from a market. He completed his creation in less than a year, with costs of production and living expenses amounting to Rmb300,000 ($49,000). However, the robot, which measures 2.1m high and 48kg in weight, turned out to be too tall and heavy to walk out of the front door of his home. It can perform simple movements with its hands and legs and also mimic human voices.
