Summary
This engineering study created a millimeter-scale wheeled robot that converts fluid flow into mechanical power for travel through complex pipes. The robot moved against water flow, switched direction or paused through magnetic or mechanical controls, adapted to different pipe geometries with soft kirigami wheels, and carried inspection payloads without an onboard battery. A UID UCT-2112 wireless temperature sensor served as a demonstration payload.
