Dosa Making Robot

India is the second largest populated country in the world with more than 1.3 billion people having diverse culture, languages, food habits and tastes etc. Rice is a common staple food consumed by people all over India. A variety of food items can be prepared with rice including rice flakes, idly, appam, dosa etc. Of all these, dosa is one of the most popular dishes in India, usually consumed as breakfast and sometimes even as dinner.

The Central Food Technological Research Institute of India has provided the list of ingredients to prepare dosa batter including rice, black gram, flour, sodium bicarbonate, sodium chloride and tartaric acid. Dosa is prepared in several sizes, shapes and toppings. There are roughly around 400 varieties of dosa. Quantity, time and human effort are the three main factors considered in the design and manufacturing of this machine. In places like restaurants, canteens etc. where huge quantities of dosas have to be prepared, traditional hand cooking of dosa is a time consuming process. In addition, people might have to wait longer time to get their favorite dosa. This machine can prepare one dosa in approximately 40 seconds on an average, whereas traditional hand cooking method takes about 180 seconds to prepare one dosa.
