Until now, robots have carried their pretty weak brains inside them. They've received instructions-such as take this, or carry that-and done it. Not only that, but they've worked in environments such as factories and warehouses specially designed or adapted for them.

Cloud robotics promises something entirely new: robots with super-brains stored in the online cloud. The thinking is that these robots, with their intellectual impact, will be more flexible in the jobs they do and the places they can work, perhaps even speeding up their arrival in our homes.

Google Cloud and Amazon Cloud both have robot brains that are learning and growing inside them. The dream behind cloud robotics is to create robots that can see, hear, understand natural language and the world around them.

The Fetch Cloud Robotics Platform is a cloud-driven Autonomous Mobile Robot(AMR) solution that addresses material handling and data collection for warehouses.

One of the leading players in cloud robotics research is Robo Brain, a project led by researchers at Stanford and Cornell universities in the US. Funded by Google, Microsoft government institutions and universities, the team are building a robot brain on the Amazon cloud, learning how to integrate different software systems and different sources of data.

Another one to watch is the Everyday Robot Project, by X, the 'moonshot factory' at Alphabet, Google's parent company. The project aims to develop robots intelligent enough to make sense of the places we live and work. They're making headway too-testing cloud robots in Alphabet offices in Northern California. So far, the tasks are simple, such as sorting the recycling(pretty slowly says X), but it's the shape of robots to come.

Optical(光学的)fiber is a flexible line of glass capable of carrying information over long distances. Scientists Dr. Robert Maurer. Dr. Peter Schultz, and Dr. Donald Keck invented the first low-loss optical fiber in 1970. Inspired by their belief that information could be sent through light, they spent four years experimenting with different kinds of glass until they succeeded.

Optical fiber was an answer to consumer demand for increased bandwidth (带宽). Beginning in the 1960s. the telecommunications industry realized that the existing copper wire infrastructure(基础设施)could no longer keep up as communications traffic increased. Optical fiber changed the telecommunications industry greatly because it, unlike copper, offered limitless bandwidth. Because of those qualities, optical fiber has become the backbone of the networks that we use today to send voice, data, and video around the world.

The first optical fiber was celebrated for having a total attenuation of 17dB/km. Today, there are optical fibers with attenuation as low as 0.17dB/km, which translates to signal loss being 100 times better than the first one. As a result, optical fiber is the preferred medium for fast. reliable communications networks.

Today, optical fiber provides the infrastructure for broadband connectivity all around the world. Optical fiber supports all the communications and interactive technology we use every day. Because of the global fiber network, you have instant access to voice, information, and video through devices such as smartphones, computers, high-definition TV. CPS, and game systems through which you get directions, send email, conduct research. join social networks, shop, and download music, movies, and more.

As has been the case from the very beginning, one driver that shapes the future of optical fiber is market demand. Optical fiber continues to create new opportunities in how we live, work, and play. Innovations such as Cloud Computing will enable us to partner with technology in a way never before possible.

Scientists have discovered many ways of using technology to help athletes improve various aspects of their performance. Each of these has something different to offer athletes, such as performance data, health or lifestyle information, increasing speed or strength and many more useful purposes. 【小题1】

Video analysis is now used in a wide range of sports. The analysis allows individuals, teams and coaches to assess strengths, weaknesses, mistakes and areas that require further training. 【小题2】 It can be achieved through better training programs and by implementing (实施) new strategies.

【小题3】 Coaches are constantly tracking and monitoring the performance of athletes to see whether they are improving. New technology is allowing coaches to measure performance more accurately. This allows coaches to see even smaller gains in the performance of an athlete.

It has long been known that sleep is important for athletes. Their bodies need to sleep to get enough rest and to allow their bodies to rebuild cells. 【小题4】 For these reasons, there is now technology that tracks an athlete’s sleep. Not only does it track how much sleep the athletes are getting, but it also monitors when they sleep, their sleeping patterns and the quality of their sleep.

【小题5】 Using it allows athletes to practice moves such as throwing in a virtual space with a reduced risk of injury. This gives them a safe way to improve various elements of their performance.
