On a trip to India I went to a Zoo where I took a bus to tour the enclosures for the tigers, lions, and bears. Between each species there were a set of gates to make sure the animals didn't mix. There were people who operated the gates rather than having an automated system that did the same thing. To your point, in India it is cheaper to have a human being do that work than a machine, much less a robot. It will take a long time for the economics of robots to catch up on really cheap labor in the developing world.
