 navigate in three dimensions, make autonomous decisions, and execute tasks with minimal human intervention. ToolKITT has been deployed on third party commercial ROVs and competing robotic platforms, enhancing our ability to offer advanced inspection and intervention services. This software also plays a critical role in next-generation inspection services, a key industry need for ensuring the integrity of subsea pipelines and offshore infrastructure. The Olympic Arm is a fully electric subsea manipulator designed for complex intervention tasks on both work-class ROVs and Aquanaut. Its patented electric actuators replace traditional hydraulic systems. The strategic acquisition of SeaTrepid International LLC (“SeaTrepid”) intends to integrate Nauticus AI-driven autonomy software, ToolKITT, into SeaTrepid's existing remotely operated vehicle (ROV) fleet. The combination will showcase unprecedented advancements in power efficiency and operational performance across the industry. The ability of ROVs and Aquanaut to seamlessly communicate at depth unlocks new service opportunities, enabling two autonomous systems to collaborate in delivering cutting-edge underwater solutions.
