A restaurant in India's southern Chennai city is trying to revolutionise customer service by introducing robot waiters to deliver food and drinks.

At the 'Robot' restaurant, a tray-wielding humanoid roams the eatery, delivers food to patrons and collects the dirty dishes and takes it back to the kitchen.

The restaurant formerly known as 'Momo' was re-launched as 'Robot' after the founding partners Venkatesh Rajendran and Karthik Kannan decided to include technology with gourmet.

Customers can order food at this restaurant that largely comprises of Thai and Chinese cuisines using only phone tabs that are placed at every table.

Use of service robots is a common phenomenon in many countries.

The demand for service robots is expected to accelerate in the next three years as robots - already used to perform tasks such as assisting medical surgery, milking cows or moving objects around warehouses - become more popular for domestic and personal use.
