Motion Control Challenges for Deep-Sea ROVs

摘要

Deep-sea remotely operated vehicles (ROVs) present motion control design engineers with some difficult challenges. Applications may include ROV propulsion, position thrusters, dive vanes, rudders, or robotic arms. Some problems are common to all of them. Corrosion. Seawater is very corrosive, and materials that are commonly used in electric motor construction are not suitable for seawater exposure. While 303 and 304 stainless steel are reasonably corrosion-resistant, for long-term exposure, 316 stainless steel, or some of the more exotic materials such as titanium, is preferred.
