They seek to expand the flight autonomy of drones with wireless remote charges



The batteries are limited to half an hour and would prevent the landing to recharge the batteries



   The drones came to society as a recreational element, however it is increasingly common to see them in action in other industries. For example, in the filming is already a more than usual element, and transport companies such as Amazon are already planning the use of these to circumvent the limitations of traffic.

However, its small size involves the incorporation of small batteries and therefore lower autonomy. The average of the batteries that give life to the electric motors of these aircraft is around 30 minutes.

   A team of researchers from Queens University in Belfast has created a wireless charging system that allows to extend the flight range of drones so they can operate on continuous flights.

A device that copies the technology used to charge smartphones, tablets without having to use cables. However, this mode requires that the electronic device be next to the wireless charging base.

To avoid the forced landing of drones, researchers have proposed a technology that allows to transfer up to 200 W in distances of up to 25 meters. "We use a special antenna that sends energy in a specific direction, a technology that is applied to communication satellites and could be applied to transfer energy wirelessly," says Neil Buchanan, project manager.

A device that needs the use of a special antenna on the ground and a receiver designed to recharge the battery in the drone while it is flying through the air. In this way the flight hours could be extended without having to have the drone on the ground to change the batteries.

92% of Spaniards connect to the internet at least once a day Half of the world's population is connected, reaching more than 4,000 million mariners    For the first time in history, the Network of networks reaches 4,021 million people who browse it, a figure that assumes that the Internet reaches half of the world's population, according to data from the Digital report in 2018 by Hootsuite. and We are Social. An increase in users who also move to Spain, where the figure has grown by 2 million to reach 39.4 million active Internet users , which means that 85% of Spaniards already have access to the network. "With 4,000 million online users, connectivity has already become a way of life for most of us. However, while Internet companies strive to provide service to the next billion users, we will see important changes in the coming months, "says Simon Kemp, global consultant at We Are Social.    According to the Digital 2018 report, Spaniards spend 5.20 hours a ...

Autonomous boats will arrive in Europe in 2017 The waters of the canals of Amsterdam will receive the first robots ships    If the autonomous cars begin to accumulate kilometers by the highways of the United States, to the other side of the Atlantic Amsterdam prepares to receive the first boats without captain. "Imagine a fleet of autonomous boats for the transport of goods and people," Professor of the Massachusetts Institute of Technology Carlo Ratti said in a statement from this research center. The Amsterdam Institute for Advanced Metropolitan Solutions is working on a project that will culminate in 2017 with the first trips through the capital's canals with robot ships.   The scientific director of the Dutch center, Arjan van Timmeren, said that these boats "offer enormous possibilities" and could have application in environmental and health issues, such as detecting diseases in advance once progress is made in relation to underwater robots. The project wil...

Artificial intelligence takes over the drones

Artificial intelligence takes over the drones An MIT mapping system allows unmanned aircraft to dodge obstacles at low speed     Can a drone only dodge an obstacle? The answer is yes. The Laboratory of Computer Science and Artificial Intelligence (CSAIL) of the Massachusetts Institute of Technology has managed to provide artificial intelligence to a small aircraft to fly through forests and warehouses. Nanomap, the new alternative navigation system allows you to fly over and avoid obstacles, as long as the speed of the device does not exceed 30 kilometers per hour.    Excessively safe maps will not help if you want drones that can operate at higher speeds in human environments," says graduate student Pete Florence, lead author of a new related document. "An approach that is more aware of uncertainty gives us a much higher level of reliability in terms of being able to fly close and avoid obstacles ." Shocks Many existing approaches are based on complex ...
