Robot can jump on the water

Researchers from two faculties, Kim Ho-young and Cho Kyu-jin of Seoul National University's Aerospace and Engineering Faculty, have successfully developed the tiny robot that can jump on water surface

Successful robots can jump on the water

The robot mimics the shape and behavior of the spider in this water is quite small, only 10 cm long and 68 mg weight.

KBS World said, "In order to understand how the water spider behaves when it launches through obstacles, scientists have video-recording and then slowing down, thereby analyzing motion. They noticed that the water spider had four paws feet, but when it was about to jump it would shrink and pop up into the air. When it falls back to the water, it expands to reach the feet by making the most of the water's surface tension.

Gizmag said that after several prototypes, the researchers created insect robots that were 16 times more powerful than their body weight. The leg of the jump to jump or leg out is perfect as no other spider running water in nature.

Scientists believe that water spiders will be very useful when monitoring and monitoring areas where natural disasters and pollution are difficult for people to reach.
