An aquatic microrobot can walk or run on water, mimicking the amazing abilities of the 'water strider',a long legged insect that effortlessly skims across pond and lakes surfaces.
The bionic bot is a vast improvement over previous devices of this kind that position it as a prime candidate for military spy missions, water pollution monitoring and other applications, the scientists say.
Even though the microrobot weighs as much as 390 water striders, it does not sink when placed on water, but stands, walks and runs effortlessly on its surface, the journal Applied Materials & Interfaces reports.
