In another fascinating event, titled Robosapiens, there were robots involved in "hand-to-hand combat" in a boxing ring.
The robots, two-feet high with wheels, were equipped with different weapons ranging from a chakra-type wheel, a hammer and even a sword.
The robot that knocked the rival down first was the winner. While some of the robots were controlled manually by remote from outside the ring, others had been pre-programmed to fight.
"Robotics may not be popular in India yet, but the times are changing," Pathak said.
"A lot of research is going on in this field and we have students from the undergraduate level to PhDs who contribute," he added.
He said robotics has developed over the years - from the 1950s and 1960s when the first industrial robots were introduced. They were thought of as mechanical devices used in industries for mass production.
Now they are used in different fields and have become more specialized and understand complex commands - and, in some cases, even logic."
