Chinese scientists create Terminator-inspired miniature liquid metal robot

Inspired by the shape-shifting android from the 1991 blockbuster 'Terminator 2: Judgment Day', Chinese scientists have created a new type of robot powered by liquid metal. The miniature robot is able to move when the voltage of its battery is adjusted. This causes the metal inside the robot to alter its centre of gravity, which in turn causes the wheel of the robot to move. According to researchers, such robots could be used in the future during search and rescue operations, as well as for medical purposes.
