Scientists Invent Robotic Jesus Bug That Walks on Water

Researchers have developed a tiny robot that is able to jump off the surface of water by mimicking the behavior of water striders, or skimmers, a kind of bug which has the unique ability to walk on water.

The insect moves thanks to a “torque reversal catapult mechanism,” inspired by the way fleas can jump up to 150 times their body length. The bug uses enough thrust to jump off water, without breaking the water’s surface, like a water strider.
