Robostrider is a self-propelled robot which uses similar mechanisms to real water striders in order to glide along the surface of the water. It was developed at Cambridge, Massachusetts.{{cite journal|doi=10.1038/nature01793|author=David L. Hu and John W. M, Bush | title=The hydrodynamics of water strider locomotion| journal=Nature| year=2003| volume=424| pages=663–666| pmid=12904790| issue=6949|bibcode=2003Natur.424..663H |s2cid=4362791 }}

Robostrider does not break the surface layer of the water despite leg speeds of {{convert|18|cm/s|in/s}} it generates both capillary waves and vortices while in motion, as do Gerridae. Hu and Bush state that Robostrider moves "in a style less elegant than its natural counterpart" but point out that it can cover {{convert|20|cm|in}} in five strides, with one winding.
