Surf Zone Robotic Platform
Editor's note: Reprinted with permission from the Naval Postgraduate School's CRUSER News . By Frederick E. Gaghan, Director of Program Development, Applied Research Associates Inc. The near-shore environment is one of the most dynamic and technically challenging for both man and machine. Significant research efforts have been conducted to investigate sea-floor crawling robots, but they usually involve “water-proofing” a standard ground robot and attempting to operate it underwater. These designs often experience difficulties in maintaining positional accuracy or operability due to the water flow and wave action. Over the course of several months, ARA studied two key engineering concepts for the Strategic Environmental Research and Development Program (SERDP) that directly affect the ability of a robotic system to operate in the surf-zone (SZ); 1) platform hull shape and, 2) propulsion. To address platform shape a study was completed of a horseshoe crab’s carapac
