Engineers Create Hydrogen-powered robot diver

Robots that can move on land may be used. There is an American engineer who has created a robot that could dive and move like a jellyfish. Development of robot is expected to be used in underwater rescue operations.

Robots that can act on the water is called Robojelly. Robots are still in the early stages of this hydrogen. In theory, the fuel is exhausted or will not consume energy. YonasTadesse, as the developer who wrote in the journal Smart Materials and Structures say, Jellyfish capable of doing the simple pool that makes it ideal to use as a vehicle.

Tadesse also revealed in his study that, "This is the first successful underwater robot that uses an external hydrogen as a fuel source."

Robojelly is equipped with artificial muscles that support movement under water. Such as jellyfish, these muscles on the inside of the circular body (shaped like an umbrella), such as a bell. When contracted, this muscle closes like an umbrella for throwing the water and push it to move forward. Then when no activities or relax, the muscle will return to its original shape.

To mimic the muscular mechanism, the robot uses a shape memory alloy that can be given to forms of muscle movement to the original. In addition, the robot jellyfish is also supported by the heat-producing chemical reaction between oxygen and hydrogen in the water, and use materials of platinum on the surface of the outer manifold.

The heat generated from the reaction of artificial muscle is being sent to the robot to produce energy. This process will be repeated, so that the robot can meregenerisasi fuel from the environment (water) alone and no longer need to use an external battery.

The robot is still in the process of development. The engineers will look ahead to how the robot can be controlled and move more freely. The study was sponsored by the U.S. Office of Naval Research to invest in profitable projects for the Navy and U.S. Marine Corps.
