Researchers have developed a new method for controlling microrobots using Helmholtz resonance — the acoustic effect produced when you blow across a glass bottle's neck. By miniaturizing the effect, they can drive the tiny robots with sound generated by airflow. The work was shared with flow visualization imagery, and physics and fluid dynamics enthusiasts are discussing its potential applications.
