A Robot Grab A Live Goldfish:-

 

Nearly transparent robots that flap, squeeze and kick when pumped with water could be the next underwater spies, at least when it comes to sneaking on aquatic animals.

In a robotic test, one of the jelly like machines were quick enough to grab and release a goldfish, a team of institute of Technology found. Researchers created a series of the transparent robots from a rubbery material called hydro-gel, including a fin-like bot (robot) that can flap back and forth, a limb that can kick, and a hand-shaped structure that can squeeze and let go.

Hydro-gels are soft, wet, bio compatible and can form more friendly interfaces with human organs. A professor from mechanical engineering and civil and environmental engineering, said in one statement. The researcher added that the group is collaborating with medical scientists to create soft hands which aid in delicately manipulating tissues and organs during surgeries.

For five years scientists work to whip up for various hydro-gel mixes made from polymers and water, to find one that was tough and stretchable. They developed process to attach the array of surfaces such as glass metal and rubber.

They noted that others have tried to craft soft robotics from hydro-gels, but their material was brittle and not very flexible, resulting in cracks after repeated use. When brainstorming ways to create soft robots from their hydro-gels, the researchers looked to nature, particularly at glass eels, these tiny, transparent are soft like hydro-gels and manage to migrate unscathed over long distances to their riverine habitats. The robot is totally transparent and it very hard to see. When you release the fish its quite happy as the robot is very soft and doesn’t damage the fish. Imagine a hard robotic hand would probably squash the fish.

Researcher’s team is now dreaming up various applications for the hydro-gel robots, while also playing around with the hydro- gel recipe to customize it for particular uses, a robot used in medical field, for instance, they may not completed transparent, while another application not require stiffer hydro-gel.

Google’s New App Allo Must Not be Used, says Edward Snowden

Google’s New App Allo Must Not be Used, says Edward Snowden

Google’s new chat app, Allo should be deleted, says Edward Snowden on warning people not to use it, as it avails Google to read everything that they say.

Google’s new chat app was finally released after showing it off over the summer. It has a robot that watches everything what people say and then stores it for analysing, to later improve the app itself.

Indicating that chats are stored on Google’s servers indefinitely, the company had earlier said, that the messages would be stored temporarily, which would limit any hack of the data stored. But with this app, Google won’t be doing the needful, as it will keep hold of all conversations.

Google will improve parts of the app, like smart replies through the use of that data by taking queue from the conversations, which would suggest people what they should say to their friends. Also Google would use the same data to target ads on users in the future. Since those conversational data might include some sensitive data, it could lead to breach of them too.

Google may also appear to work side by side with the law as they would be keeping track of all messages, to be easily accessible by law enforcement with warrants, which other apps like iMessage or WhatsApp can’t do, as both of them earlier did not give information access to the authorities.

Snowden had sent out several tweets telling people to not use Allo;

“Free for download today: Google Mail, Google Maps, and Google Surveillance, he wrote. That’s #Allo. Don’t use Allo”

Another one was, “What is #Allo? A Google app that records every message you ever send that makes it available to the police upon request”

Earlier this year after Allo’s showcase at Google’s I/O conference, Snowden had told that Allo was dangerous.

A Google spokesperson said, “We have given users transparency and control over their data in Google Allo, and our approach is simple, your chat history is saved for you until you choose to delete it. You can delete single messages or entire conversations in Allo. He added that there is an option to chat in Incognito mode, where messages are end to end encrypted, where also you can set a timer to automatically delete messages for your device and the person you’re chatting with at a set time”.
