Há mais ou menos um ano fiz o último post sobre essa tecnologia revolucionária e polêmica que invadiu o mundo, literalmente. Volto agora com este post “dois-em-um”. Confiram porque o que posto agora é o “estado da arte” nessa tecnologia !


MIT cria drone que pesa menos de um grama e se dissolve ao finalizar o serviço

93819.152707-Drone-dobravel

Com a popularidade dos drones, eles estão se tornando a cada vez menores e mais práticos de carregar. Mas o Instituto de Tecnologia de Massachussetts (MIT), nos Estados Unidos, criou uma versão um tanto quanto curiosa do robô.

Inicialmente, o drone é pequeno, pesa apenas menos de um terço de um grama e possui 1,7 cm de comprimento. Ao ser ativado por uma fonte de calor, o objeto começa a se dobrar e desdobrar, como se fosse um origami, para adquirir uma forma um pouco maior, chegando a um formato indefinido de 3 cm. Ele é capaz de andar, passar por obstáculos e até mesmo nadar.

O minúsculo robô funciona com a ajuda de dois conjuntos de ímãs, sendo um feito de neodímio que fica integrado ao próprio robô, e mais quatro bobinas eletromagnéticas que ficam em uma superfície operacional que atraem e repelem os ímã conforme necessário. O que faz com que o pequeno robô se mexa é o circuito magnético de 15 Hz.

O drone é descartável e, para que ele se desintegre, basta colocá-lo dentro de um recipiente com acetona. Feito isso, a estrutura externa do gadget some completamente, restando apenas os ímãs.

A equipe do MIT, liderada por Shuhei Miyashita, apresentou o robô no evento ICRA 2015, que aconteceu em Seattle nesta quarta-feira (28.05). Os cientistas esperam que, futuramente, o drone se dissolva completamente e seja capaz de se dobrar dentro do próprio corpo, operando de forma autônoma e desaparecendo sem deixar vestígios.

37 incredible drone photos from across the globe that would be totally illegal today

Photographer Amos Chapple captures the world’s most famous landmarks — from the Taj Mahal to the Kremlin — using a drone.

Taj Mahal as the day’s first tourists trickle through the gates.

When the commercial drone first hit the market in 2013, Chapple says he sifted through new product reviews, searching for the right model to help his art take flight.

Finally, Chinese technology company DJI came out with the Phantom drone and Chapple was sold.

Paris’ Sacré-Cœur, glowing in a hazy sunrise.

The Phantom allowed him to shoot from almost 400 feet in the air, and take 100 or so images during a single flight.

He wasted no time in getting started. Agencies, tourism bureaus, and other clients commissioned Chapple for photos of iconic sites, such as Hotel Ukraina in Moscow, Russia, seen below.

Here’s another view of the church at sunset.

The church was built only as an epitaph to the murdered Tsar and wasn’t intended for public worship. A patch of the cobbled street on which the Tsar lay mortally wounded is preserved within the old church, now open to the public as a museum.

Chapple’s drone also floated over the Blue Mosque in Istanbul, Turkey.

In the early days, Chapple flew the drone in busy areas, but he quickly realized that could be dangerous.

Known to the locals as “Hill 3,” this knoll jutting above Mumbai’s northern slums is no more valuable than the land below. Access to running water, which the hill lacks, is far more valuable than any view.

His first drone had a design flaw which caused a propeller to fly off mid-flight.

He crashed a second one recently during a commercial shoot in which he was forced to use an unfamiliar model of drone. At about 100 feet up, he lost control and the drone disappeared. After chasing it down, he found it smashed to bits. He suspects Wi-Fi signals scrambled the drone’s radio communication.

Even though he’s flown his drone more than 1,000 times now, Chapple always runs the risk that something will go wrong.

The Lotus Temple, dotted with pigeons at sunrise. Designed by an Iranian exile, the building serves as the center of the Bahai’i faith in New Delhi, India.

And frankly, the drones freaked people out. “It’s a nuisance now that it’s no longer a novelty,” Chapple says.

Now, Chapple avoids people as best he can. “I’m just using it at dawn, or in isolated places where I’m not annoying people trying to enjoy a stroll,” he says.

The angel atop the Alexander column in Saint Petersburg, Russia. Built after Russia’s victory over Napoleon, the column’s 600-ton granite trunk was tipped into place by 2,000 soldiers. It balances without any attachment to its base.

Sometimes, the best pictures don’t require much altitude. Here, two wrestlers practice the ancient Indian sport of Kushti in a pit they dug.

The drone doesn’t allow Chapple to see what he’s photographing. While it may snap 100 photos, only 10 to 20 images will be framed in a pleasing way.

The Peter and Paul Cathedral in Peterhof, in Saint Petersburg, Russia, with the palace and gardens in the background. Beyond, the Finnish Gulf is obscured by fog. During WWII, Nazi armies occupied Peterhof, destroying it almost completely during their retreat.

“When you’re paying $1,000 an hour for a helicopter flight, you make absolutely sure you’re going to get some sunlight,” Chapple says.

The star fort at Bourtange, Netherlands. Three centuries after the last cannonball was fired in anger at the fort, it now serves as a museum and the center of a sleepy farming village in eastern Holland. The low, thick walls were designed to offset the pounding force of cannon fire.

“As a result, most aerial shots [are] blue, bright, sunny, and boring,” he says. “My best shots have been in unusual weather, but it’s taken several flights to achieve. That kind of experimentation would have been impossibly expensive with a helicopter.”

A ruined college in Gali, Abkhazia, near the “border” with Georgia, where ethnic Georgians made up 96% of the region’s pre-war population. Most fled, or were driven out of their homes after the war. Today Gali is a twilight zone of empty buildings and overgrown farmland.

In 2014, the Federal Aviation Administration made it illegal to fly drones for commercial purposes, including photography. Other countries followed suit.

The windswept Liberty Statue, overlooking Budapest. Built in 1947 by the new communist rulers for the “Liberating Soviet Heroes” the inscription was amended swiftly after the USSR collapsed, “To the memory of all those who sacrificed their lives for the independence, freedom, and prosperity of Hungary.”

Russian authorities denied him permission to fly above the Kremlin in Moscow because he was a foreign citizen.

He did it anyway. Over the course of two days, he scoped out an area tucked out of sight from the police. He waited for a burst of traffic to block the noise of the drone and got his shot.

The Palace at Petergof, perched on a bluff overlooking the sea some 19 miles from central Saint Petersburg.

“I ended up snatching the drone out of the air and running through the alleyways to get away,” Chapple says. “It was risky, but so much history has walked through that space, I just couldn’t resist.”

The Hermitage Pavilion near Saint Petersburg, Russia, wreathed in dawn mist. The little “whipped cream” pavilion was an example of the decadence which would eventually topple the Tsarist autocracy. It was famous for parties where tables laden with food would rise from beneath the floorboards into groups of delighted guests.
