Mobile robot for fluid-based environments

In-pipe inspection robot with an open-body design and impeller for fluid flow maintenance

This technology features a mobile robot capable of navigating fluid environments by utilizing a motor and impeller positioned along the central axis of a cylindrical open-frame structure, allowing for self-propulsion while maintaining fluid flow. A crushing unit at the front of the motor shaft and an impeller at the rear enable the robot to simultaneously break down, collect, and clear debris while in motion.

Existing robots used in narrow pipes or fluid environments often obstruct fluid flow and struggle to efficiently combine self-propelled movement, data collection, and debris removal.

This technology introduces a cylindrical body with open front and rear ends, a propulsion structure that minimizes flow resistance using a motor and impeller, a rotating shaft-linked debris crusher, and a rear debris collection unit. Air bearings installed on the outer wall prevent collisions and maintain stability, allowing the robot to navigate pipe interiors reliably. Applicable to the inspection and cleaning of water mains and piping systems, it significantly reduces maintenance costs by performing movement and debris removal simultaneously without disrupting fluid flow.
