NEW YORK, July 2 — Every year, a small horde of robots descend upon the otherwise peaceful town of Worcester, Massachusetts. Their creators —ranging from high school and college students to families and couples — come for a chance to win US$1.5 million (RM6 million) at a Nasa sponsored competition.

In June, about 20 teams tried to pass level one to win more than US$5,000 and more importantly, qualify for the round with the big prize.
