Taking artificial intelligence a step further, a new Socially-Aware Robot Assistant (SARA) took the participants of the World Economic Forum (WEF) here by surprise by understanding their spoken words and non-verbal behaviour to build a relationship. Developed by students and professors of prestigious Carnegie Mellon University (CMU) as a research project, SARA became a key exhibit at the WEF annual meeting held in this ski resort town last week. CMU President Subra Suresh, who was here for the WEF, said the university would also take SARA to other parts of the world, which may include India, for exhibition and eventually, it may be licensed to some company or organisation for commercial use, but any decision on that will be taken by the persons concerned and professors at the university. "With technology advancing so fast, one of the opportunities for us is whether we can combine robotics, artificial intelligence, machine learning etc to create tools that will have positive impact on society. This is how SARA has come out," Suresh told PTI in an interview here on the sidelines of the WEF meet.
