Underwater robot jellyfish is your new overlord

Created by a research team from the University of Texas, this robotic jellyfish extracts the hydrogen fuel it needs to keep going as it swims. Basically, it’s a robot that breathes underwater.

The extraction of the hydrogen fuel from the water is accomplished by the natural motion of the robot’s artificial muscles as it swims. Just like a real jellyfish, Robojelly draws water into its body area, then expels it to create propulsion. As the robot draws water in, the aforementioned nanotubes create an exothermic reaction as the mixture of hydrogen and oxygen in the water passes over and through them. The heat generated by this reaction is then converted into usable energy, theoretically allowing it to run indefinitely since it can create its own fuel. Of course, there are several real-world dynamics that would hinder that process, but it’s an interesting concept nonetheless.
