For anyone who hates doing yard work, your new best friend may have arrived. A robot can autonomously shovel snow, collect leaves and cut grass.“We’re trying t o help people not spend time on yard work，”said Steven Waelbers, the designer of t he robot. “We want people to enjoy t heir free time with their family.”The electric robot can run by itself in right directions with the help of two beacons(信号塔) that must be placed in the yard. the robot includes a camera and ultrasound sensor (超声传感器) that Waelbers said would stop quickly when it finds pets and people.Owners of the robot will need t o regulate t he values stored in the robot. then it will confirm the task it’s going to take. Before the robot operate by itself, an owner must manually wheel it around the yard 一 taking it around any obstacles like trees, bushes or mailboxes. By doing this, the robot is taught how long and wide the lawn is, and won’t accidentally(不小心) destroy your rose hush or run to the neighborhood.Once this setup is complete, and the $3,999 robot has been trained on where to cut grass, rake leaves and shovel snow, it operates without any supervision.Waelbers has always loved to build robots and play with electronics. He started work on a high-tech company after his father asked him to make a robot that would shovel snow for him. Waelbers plans to start sales in early 2017.26.

共用题干The Robot ManAccording to Hans Moravec,universal robots will take over all the physical activities that we engage in,leaving us with little to do.Moravec sees four generations on the road to true universal robots. The first generation will be here by 2010 and will consist of free-ranging robots that can navigate by building an internal mental map of their surroundings.In new situations they'll be able to adapt,unlike today's mobile industrial robots.These robots will have the computing power to cope with simple speech and text recognition,and will be used for tasks such as domestic clean-ing.The second generation will arrive around 2020 and will be distinguished by the ability to learn .Second generation robots are programmed with sets of primitive tasks and with feedback that provide"pleasure"and"pain"stimuli .For example,a collision provokes a negative response,a completed task would be positive.Move forward another ten years to 2030 and you get to generation three.This robot can build internal simulations of the world around it. Before beginning a task,it can imagine what will happen in order to predict problems.If it has a free moment,it can replay past experiences and try variations in order to find a better way of如ing things next time .It could even observe a person or another robot performing a task and learn by imitation.For the first time,we have here a robot that can think.By the time we get to generation four in 2040,Moravec predicts that robots will be able to: match human reasoning and behaviour;generalise abstract ideas from specific experience;and, conversely,compile detailed plans of action from general commands such as"earn a living"or "make more robots".The Moravec manifesto（宣告）runs something like this. As robots start to become useful in generation one,they'll begin to take on many tasks in industry.Driven by the availability of this cheap and tireless labour force,the economy will boom and the demand for robots will grow so rapidly that they will soon become lowcost commodity items.So much so that they'll move into the home,where the domestic robot will relieve us of many chores.With increasing automation in generations two and three,the length of the average working day will plummet,eventually to near zero. Most people will be unemployed as robots take over not just primary industry,but the service economy too.Moravec sees the fourth generation as an opportunity to surpass our human limitations.These future machines will be our"mind children".Like biological children of previous generations,they will embody humanity's best hope for a long-term future. What does Moravec think of these future robots?A: They will look like previous biological children.B: They will be humans' mind-children.C: They will create a dangerous world.D: They will rule the world.

《第十三篇 Affectionate Androids》 Computers are now powerful enough to allow the age of humanoidrobots to dawn1. And it won’t be long befe we will see realistic cyber companions, completewith skin, dexterity, intelligence.They will be programmed to tend to yourevery need. Will we ever want to marry robots? Artificial intelligenceresearcher David Levy has published a book claiming human-robot relationshipswill become popular in the next few decades. ____1____ Will humans really be able to fm deep emotional attachments tomachines? It will, in fact, be relatively easy to fm these strong attachmentsbecause the human mind loves to anthropomphize: to give human attributes toother creatures—even objects. F example, researchers in San Diego recently put a small humanoidrobot in with a toddler playgroup f several months. ____2____The childrenended up treating it as a fellow toddler. When it lay down because itsbatteries were flat，the kids even covered it with a blanket. In a few decades, when humanoid robots with plastic skin look feel very real, will people want to fm relationships with them? What if thebots could hold a conversation? And be programmed to bethe perfect companions—soul mates,even? ____3____ And like those toddlers inthe experiment, they will be veryaccepting of them. The next question, then, is whether there is anything wrong withhaving an emotional relationship with a machine. Even today there are peoplewho fm deep attachments to their pets use them as substitutes f friends even children. Few consider that unethical. ____4____ F those who always seem to end upmarrying the wrong man woman, a robotic Mr. Ms. Right could be mighty tempting. As the father ofartificial intelligence, Marvin Minsky, put it when asked about the ethics oflonely older people fming close relationships with robots: “If a robot hadall the virtues of a person was smarter me understing, why wouldthe elderly bother talking to other grumpy old people?” A robot could be programmed to be as dumb smart, as independent subservient, as an owner desired. And that’s the bigdisadvantage. Having the perfect robot partner will damage the ability to fmequally deep human-human relationships. People will always seem imperfectincomparison. When you’re behaving badly, a good friend will tell you.____5____ People in relationships have to learn to adapt toeach other: toenjoy their common interests to deal with their differences.It makes usricher, stronger, wiser. A robot companion will be perfect at the start. However,there will be nothing to move the relationship to grow to greater heights. 词汇： affectionate adj. 深情的 dexterityn. 灵巧，敏捷 anthropomphize v. 赋于人性，人格化 grumpy adj. 脾气暴躁的 cyber adj. 计算机的 tendv. 照料 bot n. 机器人 subservient adj. 屈从的，奉承的 注释： 1.Computers are now powerful enough to allow the age of humanoidrobots to dawn：计算机技术已经足够成熟，能够支持人形机器人的诞生和普及，进入人形机器人的时代。 练习： A.It’s easier to have a robot companion instead of a human friend. B.But a sophisticated robot will probably be even me attractive. C.And if you want to go ahead tie the knot with your specialelectronic friend，Levy saidthat such marriages will be socially acceptable by around2050. D.However, few owners will program their robots to point out theirflaws. E.Maybe your generation could resist, but eventually there will be ageneration of people who grow up with humanoid robots as a nmal part of life. F.The bot knew each child because it was programmed with face voice recognition， it giggled when tickled.
共用题干第三篇Controlling Robots with the MindBelle,our tiny monkey,was seated in her special chair inside a chamber at our Duke University lab. Her right hand grasped a joystick（操纵杆）as she watched a horizontal series of lights on a display panel.She knew that if a light suddenly shone and she moved the joystick left or right to correspond to its position,she would be sent a drop of fruit juice into her mouth.Belle wore a cap glued to her head.Under it were four plastic connectors,which fed arrays of microwires一each wire finer than the finest sewing thread一into different regions of Belle's motor cortex（脑皮层）,the brain tissue that plans movements and sends instructions. Each of the 100 microwires lay beside a single motor neuron（神经元）.When a neuron produced an electrical discharge,the adjacent microwire would capture the current and send it up through a small wiring bundle that ran from Belle's cap to a box of electronics on a table next to the booth.The box,in turn,was linked to two computers,one next door and the other half a country away.After months of hard work,we were about to test the idea that we could reliably translate the raw electrical activity in a living being's brain一Belle's mere thoughts一into signals that could direct the actions of a robot.We had assembled a multijointed robot arm in this room,away from Belle's view,which she would control for the first time.As soon as Belle's brain sensed a lit spot on the panel,electronics in the box running two real-time mathematical models would rapidly analyze the tiny action potentials produced by her brain cells.Our lab computer would convert the electrical patterns into instructions that would direct the robot arm.Six hundred miles north,in Cambridge,Mass,a different computer would produce the same actions in another robot arm built by Mandayam A. Srinivasan.Ifwe had done everything correctly,the two robot arms would behave as Belle's arm did,at exactly the same time.Finally the moment came.We randomly switched on lights in front of Belle,and she immediately moved her joystick back and forth to correspond to them.Our robot arm moved similarly to Belle's real arm.So did Srinivasan's.Belle and the robots moved in synchrony （同步）,like dancers choreographed（设计舞蹈动作）by the electrical impulses sparking in Belle's mind.In the two years since that day,our labs and several others have advanced neuroscience,computer science and microelectronics to create ways for rats,monkeys and eventually humans to control mechanical and electronic machines purely by"thinking through,"or imagining,the motions.Our immediate goal is to help a person who has been unable to move by a neurological（神经的）disorder or spinal cord（脊髓）injury, but whose motor cortex is spared,to operate a wheelchair or a robotic limb.Which of the following is NOT true of the robot built by Srinivasan?A:It was directed by signals converted from the electrical activity in Belle's brain.B:It converted the electrical patterns into instructions for the other robot.C:It was six hundred miles away from where Belle was.D:It could perform the same function as Belle did.
Rats and other animals need to be highly at tuned to social signals from others so that can identify friends to cooperate with and enemies to avoid.To find out if this extends to non-living beings,Loleh Quinn at the University of California,San Diego,and her colleagues tested whether rats can detect social signals form robotic rats.They housed eight adult rats with two types of robotic rat-one social and one asocial一for 5 our days.The robots rats were quite minimalist,resembling a chunkier version of a computer mouse with wheels-to move around and colorful markings.During the experiment,the social robot rat followed the living rats around,played with the same toys,and opened caged doors to let trapped rats escape.Meanwhile,the asocial robot simply moved forwards and backwards and side to side Next,the researchers trapped the robots in cages and gave the rats the opportunity to release them by pressing a lever.Across 18 trials each,the living rats were 52 percent more likely on average to set the social robot free than the asocial one.This suggests that the rats perceived the social robot as a genuine social being.They may have bonded more with the social robot because it displayed behaviours like communal exploring and playing.This could lead to the rats better remembering having freed it earlier,and wanting the robot to return the favour when they get trapped,says Quinn.The readiness of the rats to befriend the social robot was surprising given its minimal design.The robot was the same size as a regular rat but resembled a simple plastic box on wheels.“We'd assumed we'd have to give it a moving head and tail,facial features,and put a scene on it to make it smell like a real rat,but that wasn’t necessary,”says Janet Wiles at the University of Queensland in Australia,who helped with the research.The finding shows how sensitive rats are to social cues,even when they come from basic robots.Similarly,children tend to treat robots as if they are fellow beings,even when they display only simple social signals.“We humans seem to be fascinated by robots,and it turns out other animals are too,”says Wiles.What did the social robot do during the experiment?A.It followed the social robot.B.It played with some toys.C.It set the trapped rats free.D.It moved around alone.

共用题干Wide World of RobotsEngineers who build and program robots have fascinating jobs. These researchers tinker（修补）with ma- chines in the lab and write computer software to control these devices."They're the best toys out there," says Howie Choset at Carnegie Mellon University in Pittsburgh.Choset is a roboticist,a person who designs, builds or programs robots.When Choset was a kid,he was interested in anything that moved一cars,trains,animals.He put motors on Tinkertoy cars to make them move.Later,in high school,he built mobile robots similar to small cars,Hoping to continue working on robots,he studied computer science in college.But when he got to graduate school at the California Institute of Technology in Pasadena,Choset’。labmates were working on something even cooler than remotely controlled cars:robotic snakes.Some robots can move only forward, hackward, left and right. But snakes can twist（扭曲）in many directions and travel over a lot of different types of terrain（地形）."Snakes are far more interesting than the cars,"Choset concluded.After he started working at Carnegie Mellon,Choset and his colleagues there began developing their own snake robots.Choset's team programmed robots to perform the same movements as real snakes,such as sliding and inching forward.The robot、also moved in ways that snakes usually don't,such as rolling. Choset’s snake robots could crawl（爬行）through the grass,swini in a pond and even climb a flagpole.But Choset wondered if his snakes might be useful for medicine as well.For some heart surgeries,the doctor has to open a patient's chest,cutting through the breastbone.Recovering from these surgeries can be very painful.What if the doctor could perform the operation by instead making a small hole in the body and sending in a thin robotic snake?Choset teamed up with Marco Zenati,a heart surgeon now at Harvard Medical School,to investigate theidea.Zenati practiced using the robot on a plastic model of the chest and they tested the robot in pigs. A company caikd Medrobotics in Boston is now adapting the technology for g urgerie9 on people-Even after 15 years of working with his team’s creations,"I still don't get bored of watching the motionof my robots,"Clioset says.Zenati tested the robot on people after usinlg it in pigs.A:RightB:WrongC:Not mentioned

问答题Robot Even before the first robot was built, the subject of robotics was controversial. The word robot was coined in 1921 by a Czech playwright who wrote about a colony of machines endowed with artificial intelligence that eventually turned against3 their human creators. Although that account was fictional, the first industrial robots were in use by the early 1960s. Today, we continue to be intrigued by robots and their potential for both good and evil. Basically, a robot is any machine that performs work or other actions normally done by humans. Most robots are used in factories to make products such as cars and electronics. Others are used to explore underwater, in volcanoes and even on other planets. Robots consist of three main components: a brain, which is usually a computer; actuators and mechanical parts such as motors, wheels and gears; and sensors for detecting images, sound, temperature, motion and light. With these basic components, robots can interact with their environment and perform the tasks they are designed to carry out. The advantages are obvious — robots can do things humans just don’t want to do, and they are usually more cost effective. Robots can also do things more precisely than humans and allow progress in medical science and other useful advances. But, as with any machine, a robot can break down and even cause disaster. There’s also the possibility that wicked people will use robots for evil purposes. Yet this is also true with other forms of technology such as weapons and biological material. Robots will probably be used even more in the future. They will continue to do tasks where danger, repetition, cost or the need for precision prevents humans from performing. As to whether they will be used for good or evil, that depends on the nature of the humans who create them.
问答题There are robots all along, making our lives easier. Some of them, like the (1) _______pocket calculator, can work much more quickly as human beings can. And they (2) _______rarely make mistakes. In some ways robots are better than people.. They work quickly, but not tomake mistakes. They do not get boring doing the same job over and over (3) _______again. And they never get tired. So are robots very useful in factories. They can be taught to do many (4) _______different jobs. First their electronic brains must show how the job is done. A (5) _______person moves the robot’s “arms” and “hand” through each part of the job. Therobot’s brain remembers each move. When the robot is put to work on its itself, (6) _______its brain controls the rods, wheels and motors which move its arm. When the robot needed for a new job, its electronic memory is “wiped (7) _______clean”. Then it is taught how to do its new task. If the robot’s hand stops to work, or if something gets in the way, it (8) _______cannot do the next part of the job. So it starts and signals for help. Then a (9) _______human engineer attends to the fault. Robots are also used for doing jobs which are dangerous. They canmove objects which are too hot or too heavy to people to handle. They can (10) _______work in places which are too hot or too cold.
