A microbot have been developed by Chinese researchers that can repeatedly jump over across the surface of water without tanking. They have a porous, highly repellent nickel foam coating so that the strider like bot legs are able to stay afloat with every 14cm leap it makes, despite its high weight of 1100 water striders

As reported by scientists these tiny robots can walk on water. They could skim across water bodies to monitor water quality or can be used as tiny spies.
But practically, even the most advanced designs can only walk on water. It is difficult to make robot jump because of the downward force needed it to propel it into the air usually pushes the legs through the water surface. To overcome this nickel foam coating is used to build a true water string robot.
