A bionic robot developed by Chinese scientists recently reached a depth of 10900 metres (35761ft) in the Mariana Trench, the world’s deepest point in the western Pacific Ocean. The design mimics deep-sea snailfish, whose bones are finely distributed in a gel-like body to resist high pressure in the deep sea. Researchers from Zhejiang University in Hangzhou used polymer to create a soft artificial muscle for the robot. The self-powered autonomous robot operates on lithium batteries and comes with controlling chip circuits in its belly. The achievement made the front cover of the prestigious scientific journal Nature on March 4, 2021.
