Google Creates A Robot That Is Capable Of Learning To Walk Alone

A set of Google engineers has been able to create a robot that does not require human help, and can only learn to perform different tasks, such as walking, based solely on a previous algorithm about real environments.

The most robots that exist today require the support of an engineer and an extensive work program to give it an algorithm that has thought about each of the situations they may face, but since Google wants to go further.

This is an investigation that began long ago, first developing artificial intelligence under a virtual environment where the robot was learning how to move. However, these types of situations mean that not being specifically the real world, they can end up causing machine failures.

With the experience gained, the researchers trained a robot from the beginning in the real world by first designing a more efficient algorithm that was able to learn with fewer tests and fewer errors. For this, they had to use different techniques so that the robot could perform multiple things at the same time but without falling, learning from the failures, and introducing the solution later in the algorithm.

As the research team accumulated adjustments in the robot’s algorithm, the machine was able to walk itself through different surfaces, including flat ground, a doormat with cracks, and a foam mattress.

With this learning technique for robots, these robots could be trained in real environments so that they could move to places where they usually cannot. Assistant professor Chelsea Finn of the research team said that ” removing the person from the learning process is difficult .”

” By allowing robots to learn more autonomously, they are closer to being able to learn from the real world in which we live, rather than in a laboratory as originally done,” he adds.

Still, there is a long way to go, and for the future, researchers plan to adapt their algorithm to different robots or even several so that they can learn at the same time under the same environment.

This Unmanned Combat Drone Can Go Up To Speeds of 2,414 km h

Unmanned combat drones are not new anymore. The reason is that we have often heard of combat drones used for war purposes. But only recently Kelley Aerospace has taken unmanned combat drone technology a step further.

How not, it is known that this combat drone named Arrow can travel at speeds of up to 2,414 kilometers per hour!

The drone also comes with a body made of carbon fiber to keep it light. Besides that, the shape is very minimalist and also sharp, making it able to go very fast.

CEO of Kelley Aerospace, Ian Lim said that Arrow was presented as a UAV drone that focuses on speed but also does not leave other important sectors such as toughness.

“UAVs are better known for their toughness. But not for their speed. So that’s why with the Arrow Supersonic UAV, we can solve the speed problem,” said Ian Lim.

It is stated that currently, the Arrow drone is still in the prototype stage. His party is now trying to present a model with a scale of 1/4 which will later be used as proof of his concept.

This Researcher Successfully Created 'Smart Tattoo', Can Emit Light

Scientists have created a ‘smart tattoo’ that can be applied to human skin and shine. These tattoos rely on the same light-emitting technology found on everything from TVs and smartphone screens.

However, they can be applied in the same way as a temporary tattoo, placed on paper, and then transferred to a person’s skin. That technology can be used to make an athlete’s skin glow if they need to drink water. The tattoo can also light up as a warning if a person is exposed to the sun. They can also be applied to objects, such as food, which can signal when they have passed their expiration date.

But it is not only needed to be worn functionally, and glowing tattoos can also be used for fashion. Seeing this, a researcher from University College London, Franco Cacialli, gave his comments.

“The tattooable OLED we’re showing you for the first time can be made on a large scale and very cheaply. They can be combined with other forms of electronic tattooing for a very wide range of uses, ”says Franco Cacialli.

“This could be for fashion – for example, providing glowing tattoos and light-emitting nails. In sports, they can be combined with a sweat sensor to signal dehydration. “, he continued.

“In health care, they can emit light when a patient’s condition changes – or, if the tattoos are changed towards the skin, they could potentially be combined with light-sensitive therapy to target cancer cells, for example,” he said.

“Our proof-of-concept study is the first step. Future challenges will include encapsulating the OLED as much as possible to stop it from deteriorating quickly through contact with air, as well as integrating the device with a battery or supercapacitor. “He concluded.

However, this will not be the first time engineers have built new technology into tattoos. This statement was made by the senior author and a researcher at the Italian Institute of Technology, Virgilio Mattoli.

“At the Italian Institute of Technology, we have previously pioneered electrodes that we have tattooed onto people’s skin which can be used to perform diagnostic tests such as an electrocardiogram,” said Virgilio Mattoli.

“The advantage of this technology is that it is cheap, easy to apply and use, and is easy to wash with soap and water.” he continued.

The new study saw researchers build OLED devices just 2.3 micrometers thick, less than 400 millimeters, or one-third the length of a blood cell. It consists of an electroluminescent polymer, which ignites when an electric field is applied, which is then placed on an insulating layer and standard tattoo paper.

This is the Hyperloop, the Future Train That Will Be Faster Than Aircraft

Hyperloop is a transportation concept that was introduced in 2013. It looks like a train but its speed is claimed to be able to penetrate 1,207 Km/hour.

The person who first introduced this transportation concept was Elon Musk where he explained that the Hyperloop moves by creating a low pressure which allows the capsule to move at very high speeds.

Because it is so fast, the Hyperloop is claimed to be faster than the plane. The concept is like a train put in a giant pipe wherein the train can be humans or goods.

The train, which we think of like the capsule, will later be pulled using a vacuum. So from that the reason why this Hyperloop is very fast.

The capsules in the pipe are designed to float, either by the air cushion method or by magnetic technology. Hyperloop is basically similar to a magnetic levitation (maglev) type train, it’s just that because it is not obstructed by air pressure, the speed is much higher.

Various countries are already interested in implementing hyperloop in the future. Hyperloop Transportation Technologies, for example, announced in 2017 that it would present hyperloops in the US, Slovakia, Abu Dhabi, Czech Republic, India, Brazil, South Korea, and Indonesia.
