Georgia Tech’s entry to the 3rd Annual AUVSI and ONR Autonomous Surface Vehicle Competitions was designed following three core principles: (1) modularity, (2) robustness, and (3) cost-effectiveness. Much of the hardware was recycled from prior underwater vehicles, allowing for a cost-effective solution. The catamaran design’s hulls were built by sealing two 6in in diameter and 5ft in length PVC pipes. The structure was comprised of 80/20 aluminum pieces allowing for maximum modularity and flexibility. This design allowed the team to place amongst the middle tier of the competition for a fraction of the material cost of all the other teams.
