The killer robot passed his first test

Posted on January 22, 2017  in My Blog

QUT robotic specialists have just conducted the first tests of their COTSbot killer robot. However, the machine is not dangerous to humans because it is an underwater robot designed to destroy a particular species of starfish, thus protecting the Great Barrier Reef.

The Great Barrier Reef is home to many undersea creatures. Unfortunately, not all of them are useful to her, and some of them are dangerous, destroying delicate corals. We will also include a species of starfish called the crown of thorns, which is the most destructive to her.

Researchers from OUT have developed a special robot designed to destroy it. A machine called COTSbot has already passed its first test in Moreton Bay, Queensland, and this month another test of its effectiveness will take place. Dr. Matthew Dunbabin, the team leader responsible for creating this technology, says that it can very effectively clean coral reefs from this dangerous pest in the future and protect them from damage.

COTSbot has stereoscopic cameras, GPS sensors, five propulsors to move around and a stable position, as well as a pneumatic arm that is injected into the starfish salt solution. One such machine in an 8-hour patrol can kill about 200 starfish, so a fleet of 10 or 100 copies of a robot would be able to quickly get rid of it from the reef.…

The MacBook Pro will ruin us financially

Posted on January 18, 2017  in My Blog

Most laptops manufacturers allow users to manually replace the battery and it is not a particularly expensive operation. Unfortunately, in the case of Apple computers, we have to bear in mind that battery replacement can ruin us financially.

You’ve just bought a brand-new Retina MacBook Pro and you’re just like kids with functional hardware that looks stylish and modern in addition. Mina, however, you will know when you need to replace the battery, which, like in any laptop, will wear out sometime.

Of course, you can order replacement batteries for Apple and pay as a grain, but you can also do it yourself, with the instructions prepared by professionals from iFixit. However, even then, you should expect to spend $ 500.

It’s not a mistake, because specialists advise you to replace the entire top of the case with the battery, hence the cost. This is unlikely to happen because the battery is attached to it and not screwed on and connected to some display components.

So is it worth buying a MacBook Pro with Retina, knowing that it is a disposable one? After a few years the value of the computer will go down to such a level that replacing the battery will become completely unprofitable.…

Wireless electric car chargers will be more efficient

Posted on January 2, 2017  in My Blog

Wireless battery charging systems of different devices are undoubtedly very comfortable, but at the same time extremely inefficient. Transmission of energy by induction causes large losses, so charging the battery lasts a long time. The Oak Ridge National Laboratory researchers have, however, managed to solve the problem.

Engineers have developed a 20kW wireless charging system for electric cars that has as much as 90 percent efficiency. New technology is very secure as special electronic circuits ensure that the magnetic field is immediately switched off in the event of a threat.

Only the prototype of the charger has been created so far, so the route to the commercial product is still very far away. Besides, this is not the last word of the engineers, as the next step is to create a 50 kW power charger that would be as efficient as the fast charging systems on the market today. And the greater the power of the loader, the larger the vehicle can be loaded, so the future model would be suitable for buses or trucks.…
