 Scientists build liquid metal driven robots inspired by terminator.


According to the website of the Hong Kong South China Morning Post on October 25, the hand-sized robot includes a plastic wheel, a small lithium battery and a few drops of liquid metal. When the center of gravity of the liquid metal changes, the wheels of the robot roll, and the center of gravity of the liquid metal is controlled by changing the voltage of the embedded battery.

Li Xiangpeng, professor of robotics at Suzhou University, said: We were inspired by T-1000 in the movie Terminator 2: Judgment Day.

Li Xiangpeng, together with Zhang Shiwu of the University of Science and Technology of China and researchers from the University of Wulungong in Australia, designed the prototype of the liquid metal robot, the report said.

Their research results were recently published in the American Journal of advanced materials.

Tang Shiyang, a researcher at the University of Wollongong who participated in the study, said: In the future, we expect to further develop software robots that use liquid metals. These robots can be used to perform special tasks such as rescuing earthquake victims, because they can change shape and enter space that people cannot access.

Li Xiangpeng said his team began studying the project six years ago, when material scientists discovered the unique properties of liquid metal alloys: high conductivity, controllable surface tension and extreme flexibility.

Tang Shiyang said: We believe that liquid metal alloys can help develop self-reconfigurable robots that can change their shape. And since I saw that movie when I was 10 years old, Ive been thinking about flexible robots like the T-1000.

Reported that, although far from the frightening killing robot in the 1990s blockbuster, the researchers said that the robot they designed could take humans one step further toward a software robot made of highly adaptable materials similar to organisms.

Li Xiangpeng said: Considering the flexibility and high energy conversion of micro-nanorobots, they can deliver cancer drugs and search for cancer cells in the human body.

The team led by Li Xiangpeng has made a breakthrough in the development of gallium-based liquid metal-driven robots by using voltage transformations to trigger motion, the report said.

Gallium is a soft silver like material used in electronic circuits and semiconductors. Liquid gallium alloys look like mercury, which is often expressed as water droplets.

They sealed droplets of liquid metal alloys in solution tubes, changing the shape of the devices center of gravity and turning the wheel, the study said. This process is controlled by changing the voltage of the liquid, and the wheel can be guided to a specific direction on a flat surface. Tang Shiyang said, next, we plan to use multiple wheels to make it move in a three-dimensional environment. Li Xiangpeng said the team is also working to develop a robot similar to the BB-8 in the recent Star Wars movies, with a hemispherical head that can move freely. Scientists may even use this new way of rolling wheels to develop cars that can run without fossil fuels or motors in the future, the report said. Li Xiangpeng said, maybe in 10 years, liquid metal robots will really exist. (compile / Li Fengqin) this article source: Reference News Net editor: Zhang Zutao _NT5054
