The USRR4T-AJ underwater robot is a newly developed product specifically designed for fields such as underwater security, underwater search and rescue, underwater salvage, underwater reconnaissance, underwater scientific research and archaeology, and marine aquaculture. It is compact, flexible, and highly expandable, capable of replacing divers to work underwater for extended periods. It is suitable for various underwater environments, including oceans, lakes, and rivers.​

(1) Waterproof depth: 100 meters​

(2) High-efficiency shore-based DC high-voltage power supply ensures long-term operation of the robot and eliminates the hassle of frequent charging.​

(3) Equipped with a 1080P high-definition network pan-tilt camera capable of imaging in turbid water, featuring a built-in shallow-water green light suppression algorithm and underwater automatic fog penetration function, providing superior shooting performance in turbid water compared to similar products.​

(4) Two high-brightness fixed LED lights and two lights that move with the camera pan-tilt, offering excellent underwater illumination.​

(5) Maintenance-free, fully sealed, high-power deep-water oil-filled thrusters, with a maximum thrust of up to 12 kg per thruster; it can achieve depth-holding hovering and directional navigation.​
