6000m Heavy-duty Work Class ROV
1.Overview
VY250 robot is a 6000m class operating robot with 185KW power, equipped with a set of five-axis and seven-axis hydraulic robotic arms, and all core components are localized. It is mainly used in deep-sea oil and gas field operation, wind power and communication cable maintenance, underwater search and rescue, and other fields.


VY250 is independently developed and manufactured by our company, with 100% localization rate. It is the first breakthrough in deep-sea operational-grade ROV with high pressure resistance, navigation and positioning, power, communication transmission and multi-equipment cooperative operation technology, and is equipped with self-developed TMS to realize large water depth operation. It is suitable for deep-sea resource exploration, submarine cable/pipeline laying, etc.
