Amphibious drone lives underwater and takes aerial flight when needed

CRACUNS Drone

The longing for developing underwater drones is fast emerging as the new trend. To keep up with this craving, researchers at John Hopkins University have developed a drone which is good both in and out of water. In-fact it likes water more than land as it is capable of staying underwater for months in its base station and when needed take flight from there. Dubbed CRACUNS (Corrosion Resistant Aerial Covert Unmanned Nautical System) this waterproof drone can be attached to a submarine for missions that require underwater and aerial surveillance.

Brain-controlled prosthetic hand with individual finger movement

Mind-controlled prosthetic arm

Johns Hopkins University Applied Physics Laboratory physicians and biomedical engineers have developed a modular prosthetic limb which can be controlled with mind. Not only the hand but fingers can also be mind-controlled by the user. This brain-machine interface controls the real-time moment of individual prosthetic fingers. Using high-density electrocorticography (ECoG) array, the brain response is recorded and translated into the motor movement of fingers. The prosthetic has been developed for people who have lost their arms to disease or injury.

Paralyzed man with robotic hand wired directly into the brain can feel his fingers

 

Prosthetic hand with sensory feel

A man paralyzed for over a decade, as a result of spinal cord injury, has been fitted with a robotic hand wired directly to his brain that allows him to feel almost naturally. Using the prosthetic hand developed by Applied Physics Laboratory at Johns Hopkins University, a 28-year-old man is now able to feel not only when the hand is touched but also tell which finger is being touched.   Read More…
