An Ultrasonic Microrobot Enabling Ultrafast Bidirectional Navigation in Confined Tubular Environments (IMAGE)
Caption
- An ultrasonic microrobot achieves bidirectional high-speed locomotion (81 cm s−1) in micro-pipes via frequency modulation.
- MEMS-fabricated ultrathin piezoelectric composite film enables rapid navigation within confined pipeline (4 mm height), slope climbing (24.25°), and notable load-carrying (>36 times its weight).
- The microrobot demonstrates agile locomotion across curved pipes, pipes made of various materials, and even over water; integrated micro-endoscope camera enables real-time imaging, highlighting great potential for efficient pipeline inspection.
