Robot Plays Greeter Role

This robot you see here looks as though it was constructed from spare parts of an RC car, it is equipped with a portable megaphone and distance sensors so that it knows the location of pedestrians and how far away they are, using the portable microphone at the right time. It has the ability to send salutations to people in all half dozen official languages of the United Nations. I wonder whether someone will just record a political speech and use it to get their radical ideas across if this ever goes mainstream?
