Advanced scientific underwater robot

University of Washington recently developed a robot that can dive to a depth of 5000 meters in the ocean, has been completed successfully by scientists and engineers from the Woods Hole Oceanographic Institution and the University of Washington.

Sentry is a pioneering underwater robot which can swim in an independent manner, without wires or other connections to a research ship.

The autonomous underwater vehicle, is preprogrammed with instructions for exploration in deep waters, but also can make its own decisions about navigation on the ocean floor.

In the near future, Sentry conducted oceanographic explorations of high resolution that would otherwise be impossible.

Thanks to Sentry, have been prepared and more accurate maps to date of the Hydrate Ridge and the Axial Volcano, regions of the seabed off the coast of Oregon and Washington.

"We are changing the way that makes ocean science, launching a new era in which a set of technologies provide us with a growing capacity to explore the oceans and interact with them," says John Delaney, chief scientist of the expedition.

The robot can collect the necessary data to make maps of the seabed with a resolution of up to less than one meter.

Powered by more than a thousand lithium-ion batteries similar to those used in laptops, but adapted to extreme pressures, Sentry diving for about 18 hours and traveling 58 kilometers and can make longer trips in the future.

Sentry is designed to swim through the water like a fish or float in it as a way comparable to what makes a helicopter in the air. The ingenious design allows the vehicle hydrodynamic descend quickly from the ocean surface to depths (about 3,500 meters per minute). The novel also gives the vehicle a high stability and a remarkable balance while crossing through the flow of deep water.

The robot has built-in thrusters fins, or wings. As an airplane, the wings allow it to gain lift entrainment or time or directional, as required.

When needed, the robot can also float on the bottom without moving horizontally, to conduct inspections closely, make decisions navigation, or to rise or fall before marine rugged terrain.

The most skillful robot with high passability in the world

U.S. company Boston Dynamics presented to the public new generation four-leg device that shows staggering stability and quickness in movement in severe conditions.

The something named by its creators “Big Dog”, is presented by Boston Dynamics as " the most modern four-leg robot in the world " and "alpha dog" of the family robots of the manufacturer, which also includes and other interesting "robo-fauna".

With its size of 1 meter length, 0.7 height and weight of 75 kg. BigDog actually quite remind a big dog (or a little donkey) and can walk, run (with speeds up to 6-7 km / h), jump and climb in difficult terrain with a gradient of 35 degrees and transferring heavy and bulky loads. The mechanical "dog" draws energy from a petrol engine. It power the special hydraulic drive system, which is perhaps the most interesting thing from the widget.

The legs and the joints of the robot are also shaped like the animal and are equipped with absorbing strikes system. According to its creators, the robot may restore a part of the energy used at each step. Of course, there are built-in computer that controls the "center of balance", guide movements of the Big Dog and process information received from the multiple sensors.

BigDog is designed with the idea to create robots that are sufficiently passable to go anywhere where can reach people and animals, comment Boston Dynamics. Naturally, the program is funded by U.S. Agency for advanced research projects in the area of the defense DARPA (Defense Advanced Research Project Agency) - the same that finance and development of the Internet.

And in Boston Dynamics appear to have done a good job with the money, if judged by the curious video demonstration that the company has published on its site.

Scientists have created a female robot patient

Scientists from the Institute of Medicine of the University of Gifu city (Japan) have created the first robot patient to answer questions on how she feels and moves her body so that stress symptoms of her illness.

The purpose of the invention is to give the medical students experience "from first hand" with rare illness states. When the robot "suffers" from myasthenia gravis – nerve-muscle disease which is difficult to diagnose, leading to muscle weakness and fatigue - she says to the doctor that her eyelids are weigh and change the utterance of her face, slowly leave her shoulders and crouch forward.

For the creators of development has been difficult to make the shoulder joints and a shovels of the robot to move as a human, said Yudzo Takahashi. He says that in the future the scientists want to put in the female robot more illness symptoms and to create realistic training manual.

Given that medical students and the trainee-doctors are quick pass training in various specialties, universal robot-patient may show a wider range of conditions and diseases, rather than offer a small hospital for a month.
