Amazon has recently revealed its new machines, including its first fully autonomous warehouse robot. It’s called Proteus, and it was designed to be able to move around Amazon’s facilities on its own while carrying carts full of packages. The company said the robot uses advanced safety, perception and navigation (导航) technology, allowing it to do its work without delaying human employees.

In a video Amazon posted, Proteus was seen moving under the carts and transporting them to other locations. It sends out a green beam (光束) ahead of it while it moves, and it stops if a human worker steps in front of the beam.

Amazon’s aim is to automate (使自动化) the handling of its package carts so as to reduce the need for human workers to manually move them around its facilities. In fact, the e-commerce giant stressed that its robots were designed to create a safer workplace for people. “Our vision was never tied to a choice between people and technology. Instead, it was about people and technology working safely and harmoniously together to deliver for our customers,” it claimed.

Another new robot called Cardinal was also designed with the idea of reducing the risk of employee injuries in mind. Cardinal is a robotic arm that picks up packages, reads their labels and then places them in the appropriate cart for the next stage of the shipping process. Artificial intelligence and computer vision enable it to sort packages correctly.

Amazon has also revealed that it’s working on an AI technology that can automatically scan packages. With this scanning capability in place, human workers won’t have to pause while sorting packages: The system can quickly recognize a package that passes its camera. Amazon explained that its camera runs at 120 frames per second and is powered by computer vision and machine learning technology.

Having introduced several robots over the years, the e-commerce giant has always emphasized that their purpose is to improve safety at its warehouses. As an Amazon robotics lead put it, “Replacing people with machines is just a fallacy (谬见), and that could end with a company going out of business.”

Have you ever lost your car on a parking lot? It happens. You park and go shopping. When you get back，you have no idea where your car is. Then you start wandering around clicking on the panic button on your car keys so the alarm goes off. It can be frustrating, especially on a hot, sunny day.

No, you don’t need to install（安装）an expensive GPS system to keep track of your car. That’s too expensive. But is there a way to track your car without spending too much? Yes，now there is!

A California-based startup company was able to make this a reality. They created a tiny device that works with your smartphone，and it could be exactly what you’re looking for.

What is it? It’s called TrackR Bravo. It is a tracking device the size of a coin. It’s changing the way we keep track of the important things in our lives.

How does it work?

It’s easy! Install the free TrackR app on your smartphone, connect the app to your device and you’re ready to go! Simply connect TrackR to whatever you want to track. The entire process of setting it up only takes 5 minutes or less.

You can connect it to your keys, briefcase, wallet, your latest tech gadgets and anything else you don’t want to lose. Then use the TrackR app to locate your missing item in seconds.

“This device has saved me tons of time and money!” said Johnny Blaze.

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve get a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting — whatever. Making new friends becomes simple.

This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.

An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source batteries because they do not need it. The energy comes from the reader, a scanning device (装置), that sends out energy (for example, radio waves) that starts up the tag immediately.

Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person ) section and pays for the bill with the wave of an arm.

Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could he put every where and send information in smart network that would make ordinary life simpler.

RFID tags are a small part of this phenomenon. “The world is going to he a loosely coupled set of individual small devices, connected wirelessly.” Predicts Dr. J. Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers, Accompanied by how many biscuits.

When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.
