Title: Robot springs off water
Post by: saikat07 on November 21, 2016, 06:24:36 PM
New robotic insects can hop on water. Researchers from Harvard University and Seoul National University in South Korea studied live water striders, which can skate and leap on water, to design the robots. The bots weigh just 68 milligrams and have bodies that are 2 centimeters long and legs 5 centimeters long.

Like real water striders, the robots use water’s surface tension to support them as they jump, pushing off without puncturing the water’s surface, the scientists report in the July 31 Science. 

Both living water striders and the robots have water-repellent legs, which they rotate inward as they leap. This motion provides power to their jump.
