A sewer cleaning robot can detect, remove dirt and blockages in underground pipe networks. Combining industrial Ethernet, servo motion control technology, precision transmission technology (harmonic reducer), robot end-effectors, and other technologies, it can achieve multifunctional special-purpose robots capable of dirt removal, blockage clearance, high-pressure flushing, visual inspection, etc.

Sewer Cleaning Robot Arm

The arm of a sewer cleaning robot has improved cleaning efficiency and effectiveness compared with traditional excavators due to its extremely high degrees of freedom and flexibility. The joints of the robot arm are driven by servo motors and controllers; the harmonic reducer as a transmission component can increase torque and reduce speed, and an encoder grating installed at the end of the joint shaft provides feedback on the displacement and speed of the joint. The high torque characteristics of the harmonic reducer significantly enhance the degrees of freedom of the robot arm.

Visual Inspection System for Sewer Cleaning Robots

The control system enables remote operation of the sewer cleaning robot within pipelines without requiring workers to enter the sewer. After the camera images captured by the robot are transmitted to the controller screen, the operator identifies the location of debris or sediment based on real-time visuals. Once the robotic arm removes the main sediment via touchscreen commands, the high-pressure water gun activates the sewage flushing solenoid valve to flush pipeline walls or vacuum waste, achieving secondary cleaning and ensuring sewage cleaning effectiveness. This system addresses the historical problems of incomplete manual cleaning and significant safety risks. The high-precision characteristics of the harmonic reducer ensure the accuracy and reliability of transmitted motion data.

Development of Special-Purpose Robots

The sewer cleaning robot is a type of special-purpose robot. Thanks to continuous advancements in artificial intelligence, bionics, and new materials, the application fields of special-purpose robots continue to expand, and their functionalities grow increasingly powerful.

Reasons for Choosing HONPINE

Special-purpose robots are designed to perform specific tasks in challenging environments, requiring high technical complexity and unique adaptability. Different scenarios impose distinct requirements:

1,In earthquake rescue scenarios, robots must carry life-detection equipment to assist in inaccessible areas.

2,Underground rail inspection robots can penetrate critical zones such as substations and winch rooms, equipped with infrared thermal imagers, cameras, and sensors to collect images and detect gases.

3,Bipedal robots, with their advanced leg mechanisms, navigate complex terrain like mountainous regions.
