Mini robot to explore world's deepest sea trench

A team of Chinese scientists has developed a miniature 2.7-kilogram deep-sea robot to explore the deepest natural frontier on Earth — the Mariana Trench in the western Pacific Ocean, according to a study published in the journal Science Robotics in March.

The researchers from Beihang University, formerly known as the Beijing University of Aeronautics and Astronautics, have further consolidated China's position as one of the few nations able to explore the deepest depths of the oceans.

Headed by Professor Wen Li, researchers from the university's School of Mechanical Engineering and Automation started working on the robot's design in 2019 and completed its construction in 2021. So far, the team has collaborated with peers from the Chinese Academy of Sciences' Institute of Deep-sea Science and Engineering and Zhejiang University to use the 50-centimeter-long machine for deep-sea exploration.
