Wing morphology and stiffness are crucial in lift force generation during flapping flight. In this investigation, we present both fabrication and characterization methodologies for artificial insect wings with biomimetic morphology and stiffness using laser cutting and bonding of multilayer materials. Two distinctive achievements have been accomplished: (1) simple and versatile fabrication for the...
We present an artificial flapping-wing insect driven by a low voltage electromagnetic actuator to move laterally along a horizontal guide rail for the first time. Three distinctive achievements have been accomplished: (1) only 90mg in weight with wing span of 3 cm for the prototype; (2) high peak to peak flapping amplitude of 100.4° at 51.3Hz under a low driving voltage of 5V; and (3) measured 116...
We report an insect-size crawling robot with fast moving speed driven by electrostatically induced self-vibration for the first time. Under an applied DC voltage, the robot with a total mass of 47mg has achieved a forward crawling speed up to 30mm/s (1.5 body lengths per second). Using an integrated on-board capacitor, it can move freely without electrical powering wires for up to 10 seconds with...
