Recently, the deep-sea soft robot fish invented by Zhejiang University team appeared on the cover of the top international journal Nature. This robotic fish once dived into the Mariana Trench at 10900 meters and flapped its wings for 45 minutes under the drive of a 2500mAh lithium battery. Its research and development is inspired by the bionics of deep-sea lionfish, which looks like a deep-sea lionfish, with a length of 22 cm and a wingspan of 28 cm.

The bionic soft robotic fish developed by Tiefeng Li team is driven by a pair of wing-like flexible pectoral fins through soft artificial muscles and swims through rhythmic flapping. Through the structural analysis of the deep-sea lionfish, the research team found that the bones of the deep-sea lionfish are finely distributed in gelatinous software, which is helpful for its survival and activities in high-pressure environment.
The team adopts the strategy of "being soft" to integrate hard equipment such as control circuits and batteries into the gel-like software body; By designing the material, structure and software of the adjusting device, the robot can bear the hydrostatic pressure of 10,000 meters in the deep sea without a pressure-resistant shell.
