SubBlue Robotics

Corporate marketmarineinspectionCurated record

SubBlue Robotics builds underwater robots that inspect, clean and polish ship propellers without human divers. The system pairs an ROV base with an underwater manipulator arm of up to 3 meters carrying adaptive polishing tools, guided by high-definition cameras and navigation software with data-driven control so polishing runs can proceed around the clock, including during cargo operations. A newer biofouling capture module collects released material for onshore disposal to prevent spreading invasive species between ports. The company operates its robots as a worldwide service (Rupert Scale A polishing standard) rather than selling units.
