Applications of a Dredging Robot
Its applications are extensive.
- In urban rivers, it can remove silt and debris such as plastic bags and glass bottles from the riverbed, preventing blockages during flood season and reducing odors caused by fermented silt.
- In reservoirs, it can remove sediment and dead branches, and leaves that affect water storage capacity, ensuring a stable water supply.
- In ports, it can clear silt and shipwrecks from waterways, allowing large vessels to enter and exit smoothly.
- In industrial pools, such as sedimentation tanks at chemical plants, it can remove waste residue and sediment generated during production to prevent pipe blockages.
- It can also efficiently perform dredging tasks in oxidation ditches at sewage treatment plants and water intakes at hydropower stations.


How Does the Underwater Tank Cleaning Robotic Dredge Work?
- When operating, the robot first uses ultrasonic sensors to scan the underwater environment, creating a three-dimensional topographic map and accurately identifying the area requiring dredging.
- Then, the rubber-tracked underwater dredging robot uses non-slip tracks to navigate the waterbed, preventing slippage even on muddy riverbeds.
- Upon reaching the target location, it extends a specialized dredging device that, like a vacuum cleaner’s suction hose, sucks silt, debris, and garbage into a large-capacity collection chamber.
- Once the collection chamber is full, the robot automatically returns to the surface and discharges the waste onto a transport vehicle. The entire process requires no human involvement, making it both safe and efficient.


Functions of the Underwater Dredging Robot
- It has many practical features. It features automatic navigation, allowing it to follow a set route and automatically avoid obstacles such as underwater pipes and bridge piers.
- It is equipped with a positioning system that precisely locates the desilting location, avoiding duplicate work or missed areas.
- Its collection chamber has a capacity of 500 liters, reducing the number of round trips and improving work efficiency.
- It is also equipped with a water quality monitoring module that monitors pH, turbidity, and other indicators in real time, transmitting this data to a surface control console.
- It also has the function of an underwater tank cleaning robotic dredge, capable of penetrating deep into underwater tanks to remove dirt and sediment adhering to the walls, keeping the tank clean.

Application Examples of Rubber Tracked Underwater Dredging Robot
- In Saudi Arabia, a canal near the capital Riyadh has been plagued by years of silt accumulation, resulting in poor flow and being prone to flooding during the flood season. After the local government introduced this dredging robot, it worked eight hours a day and cleared over 200 tons of silt in just one week. The canal water level dropped by 0.5 meters, restoring smooth water flow and freeing the lives of surrounding residents from the threat of flooding.
- In Singapore, silt accumulation in parts of Jurong Port prevented large cargo ships from docking. After using the robot to clear silt, the water depth increased by one meter, allowing cargo ships to dock smoothly and increasing the port’s cargo efficiency by 30%.
- In the UAE, a reservoir in Dubai was deteriorating due to the influx of garbage from the surrounding area, affecting the irrigation of surrounding landscaping. After the robot was installed, the garbage was completely removed from the reservoir, significantly improving water quality and irrigation efficiency.
