microrobots

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.

Researchers have unveiled a paper-thin robot driven by living muscle cells that can swim its way through an underwater maze. The biohybrid device, reported by Tech Xplore, demonstrates how engineered muscle tissue can be used to propel soft microrobots through complex aquatic environments, a step with potential applications in medicine and targeted delivery.
