The mystery of how some insects can walk on water has been solved with the
construction of a lightweight robot that performs the same feat.
Using high-speed photography and the mathematical principles of mechanical
engineering, researchers discovered the secrets of the pond skater - a
long-legged creature that can skim across water - called water striders in
the US.
The robot strider, made of stainless steel wire coated in a
water-repellent, is powered by an elastic thread that pulls its legs
backwards and forwards across the water's surface, just like the real insect.
