Cool technology that used to be occupied exclusively by science fiction, invade our reality at an accelerated pace. In some cases, earth scientists have proven that they can be developed, it would seem impossible technology , but it still remains a number of hurdles that must be overcome. In other cases, these technologies are already with us.

Liquid robots

If you watched the movie “Terminator 2”, you probably have seen a robot T-1000, which could pass through difficult places, turning into a liquid. Also, he could regenerate. Scientists at the Massachusetts Institute of Technology have made their own version, which embodies the T-1000 into reality.

Defence Advanced Research Projects Agency DARPA wanted deformable (or “liquid”) robots that behave like an octopus. This means that they can penetrate into hard to reach places and grow to cover long distances. As surgical applications such liquid robot could penetrate to a certain point in the human body without causing damage to blood vessels or organs, and then carried out the surgical task. In the process of search and rescue operations robot liquid could seep through the debris and find survivors.

To achieve these goals, the scientists needed a material that can transition from the hard state (when the robot is holding tools or perform tasks) in soft (when the robot is leaking between objects). As stated in the press release Anette Hosoya, Professor MIT, «you can just make a jar of Jell-O, as if he needed to manipulate an object, it simply is deformed, not exerting pressure on the object that will try to move.”

Ultimately, the scientists chose an inexpensive foam polyurethane foam, which can be compressed to extremely small dimensions and later expanded. Then covered it with wax. Heated by wires passing through the layers of foam, wax melts, leaving the surface soft. The current can be left, if necessary. By heating the robot can also be restored.
