The robots driving India's online shopping boom

In 2011, engineering student Samay Kohli wanted to build a humanoid robot, but his professor told him it would not be possible.

Along with his fellow student Abhay Singhal, not only did they build a humanoid robot, they have built GreyOrange, a multinational robotics company based in India and operating across Asia.

Central to the growth of the country is the boom in online retailing and the need for warehouses to hold the stock and process the goods that consumers are ordering.

"We believe warehouses are everywhere and they are supposed to become more and more intelligent as consumer demand increases.'' says Mr Kohli.
