A team from the California Institute of Technology took home a $6,000 prize, after prevailing in the RoboSub Competition sponsored by Office of Naval Research (ONR) and Association for Unmanned Systems International Foundation in San Diego last month. The Caltech team was one of 46 taking part in the contest, which entailed constructing unmanned submarines. Contestants had to produce vessels capable of negotiating a complicated obstacle course, firing mock torpedoes, and weighing anchor. The teams also had to prepare journals, web sites, and videos. Other prizewinners included: Indian Institute of Technology ($5,000); Cornell University ($2,000); G.I. Nevelskoy Maritime State University ($1,500); Kasetsart University and Chulalong University ($1,500); Harbin Engineering University ($1,000); and McGill University ($1.000).
