Barlosi Underwater Desilting Robot uses a tracked chassis for efficient sludge removal in WWTPs, pump stations, and sedimentation tanks. With a high-power dredging pump and wear-resistant agitator, it handles high-concentration slurry. Its top-view visual positioning system calculates real-time underwater coordinates through a novel method, overcoming GPS signal loss for centimeter-level accuracy and full-path tracking, improving safety and intelligence.
