The Chinese are at their inventive best. Cars, planes made out of recycled materials, helicopters with wooden blades and rickshaws pulled by a robot are some of the amazing inventions from China.
Built by farmers, mechanics and workers in their inimitable style, some of these remarkable products are made from scrap!
Take a look at these mind-blowing inventions…
Home-made Robot
The self-taught Chinese inventor built the home-made robot, named "The King of Innovation", out of scrap metal and electronic wires that he bought from a second-hand market.
Tao completed his creation in less than a year, with costs of production and living expenses amounting to 300,000 yuan ($49,037).
However, the robot, which measures 2.1 metres (6.9 feet) in height and 480 kg (1058 lbs) in weight, turned out to be too tall and heavy to walk out of the front door of his house. It can perform simple movements with its hands and legs and also mimic human voices.
