US engineers have invented a robot that replicates the movement of a jellyfish as it moves through water. The robot uses artificial circular muscles that contract, ejecting water and propelling it forward through the water.

Robojelly is made from carbon nanotubes (straw-like pieces of carbon) and shape memory allows, a material that “remembers” its shape.

Powered by hydrogen, the robotic jellyfish has the potential to be its own energy source. The oxygen and hydrogen in the water react with the platinum powder that the robot is coated in and create a heat-producing chemical reaction. The heat that is produced is used to power the robot through the water.

Eventually, Robojelly is hoped to be used for underwater rescue purposes.
