Liquid Metal Robot Discovery 😳

Liquid metal discovery paves way for shape-shifting robots. It may look like nothing more than a small ball of metal, but the shape-shifting and self-propulsion abilities of a liquid metal alloy discovered by scientists at China's Tsinghua University has captured the imaginations of scientists and science-fiction fans across the world. Professor Liu Jing and his team have created what they believe could prove the first step toward developing a robot similar to the infamous T-1000 shape-shifting, liquid metal assassin from the Terminator movies. "The soft machine looks rather intelligent and [can] deform itself according to the space it voyages in, just like [the] Terminator does from the science-fiction film,"professor Liu told New Scientist. The device is made from a drop of metal alloy consisting mostly of gallium, which is a liquid at just under 30 degrees Celsius. Last year they discovered that an applied electrical current causes the gallium alloy to drastically alter its shape. Changing the voltage applied to the metal allowed it to 'shape-shift' into different formations. When the current was switched off, the metal returned to its original drop shape. But the team made their biggest breakthrough when they realized that bringing it into contact with a flake of aluminum caused a reaction creating hydrogen bubbles that allowed it to move of its own accord. Liu said it was able to 'fuel' itself for about an hour. http://www.businessinsider.com/liquid-metal-discovery-paves-way-for-shape-shifting-robotse-2015-4 #4biddenKnowledge #Terminator2 #SkyNet
