'Through various theoretical, computational and experimental studies, we found that the mechanics of flapping propulsion are actually very similar in air and in water,
'In order to make the transition from air to water, the team first had to solve the problem of surface tension.
The Robobee is so small and light it couldn't break the surface tension of the water at first.
But the researchers worked out a way of making it hover over the water at a certain angle,
By doing this, the Robobee is able to crash into the water in a controlled way and sink.'
'Water is almost 1, 000 times denser than air and would snap the wing off the Robobee
The team prevented the Robobee from short-circuiting in the water by coating the electrical connections with glue.
It also only currently swims in deionised water. Another drawback, is that as yet, the robot can't make the transition from water to air,
because it can't generate enough lift without snapping one of its wings. Solving this issue is the next challenge.'

When light passes through water, for example, its phase velocity is reduced as its wavelengths get squished together.
Once it exits the water, its phase velocity increases again as its wavelength elongates. How much the crests of a light wave slow down in a material is expressed as a ratio called the refraction index--the higher the index,
Water, for example, has a refraction index of about 1. 3 . When the refraction index is reduced to zero,

For instance, water striders collected from streams and ponds in Seoul, South korea, with bodies a half-inch long can jump more than 3 inches high on average,
"We have revealed the secret of jumping on water using robotics technology,"co-senior study author Kyu-Jin Cho,
"Using high-speed cameras, the researchers analyzed water striders jumping on water. They noticed that the insects'long,
so that the surface of the water did not retreat too quickly and lose contact with the legs.
the scientists found that the maximum force the water striders'legs exerted was always just below the maximum force that water's surface tension could withstand.
The scientists also found that water striders swept their legs inward to maximize the amount of time they could push against the surface of the water
Moreover, the shape of the tips of their legs were curved to adapt to the dimples that formed on the water's surface
the robot could leap about 5. 5 inches off the surface of the water about the length of its body and 10 times its body's height."
"Our small robot can jump on water without breaking the water surface, and can jump on water as high as jumping on land,
"Cho said. The researchers cautioned that, so far, the robot can jump only once, and it lands randomly.
