Unlike aerial drones that rely on GPS and satellite communication, underwater robots face significant challenges in deep-sea navigation due to the lack of GPS signals underwater. Most AUVs and ROVs rely on acoustic positioning systems, which become less effective at extreme depths. In deep-sea exploration missions exceeding 5,000 meters, underwater robots struggle with accurate positioning and data transmission delays. Scientists and engineers are working on next-generation sonar-based and AI-powered navigation solutions to address these challenges, but real-time deep-sea communication remains a technical barrier.

"Harsh Ocean Conditions and Equipment Durability"

Underwater robots operate in extreme environments, where factors like high pressure, strong ocean currents, and extreme temperatures affect their functionality. Saltwater corrosion, biofouling, and mechanical wear require frequent maintenance and specialized materials to extend equipment lifespan. Many deep-sea ROVs need custom-built titanium or carbon-fiber housings to withstand pressures at depths beyond 4,000 meters, making them expensive and difficult to mass-produce. Manufacturers are working on pressure-resistant materials and self-repairing robotic systems, but achieving long-term durability in harsh marine environments remains a significant challenge for the market.
