Overview

The smallest flying robot of its era. It made its first controlled flight in 2012 and was published in Science in May 2013, made possible by pop-up MEMS folding fabrication and piezoelectric wing actuators. Later variants perched with electrostatic adhesion and switched between swimming and flying. The four-winged RoboBee X-Wing (2019) became the lightest vehicle to achieve sustained untethered flight, powered by solar cells under lab lights.
