Microflier in its folded state

Caption

Researchers at the University of Washington developed small robotic devices that can change how they move through the air by "snapping" into a folded position during their descent. Each device has an onboard battery-free actuator, a solar power-harvesting circuit and controller to trigger these shape changes in mid-air. Shown here is a "microflier" in the folded state.
