Washington: Researchers have developed an insect-sized robot that mimics a water strider to jump on the surface of a body of water.

Researchers at Seoul National University (SNU) in Seoul, South Korea, Harvard’s Wyss Institute for Biologically Inspired Engineering, and the Harvard John A Paulson School of Engineering and Applied Sciences, studied a species of semi-aquatic insects called water striders.

The water strider, whose legs have slightly curved tips, employs a rotational leg movement to aid its takeoff from the water’s surface, discovered co-senior author Ho-Young Kim, professor in SNU’s Department of Mechanical and Aerospace Engineering and director of SNU’s Micro Fluid Mechanics Lab.

Kim, a former Wyss Institute Visiting Scholar, worked with the study’s co-first author Eunjin Yang, a graduate researcher at SNU’s Micro Fluid Mechanics lab, to collect water striders and take extensive videos of their movements to analyse the mechanics that enable the insects to skim…
