The coolest job in the world: developing all kinds of robots and use cases

according to science news for students, whenever you mention robots, you may think of the machine in Wall-E, which is designed to complete many boring tasks, such as compressing garbage. But now engineers are building robots that can do more interesting work. For example, snake robots can find victims after earthquakes or help doctors with surgery in the future. Underwater robots may be able to lead fish away from environmental disasters, and humanoid robots can help people with diseases or physical disabilities

programming and manufacturing these robots is a very attractive job. Many researchers repair the machines in the laboratory and write computer software to control them. Howie choset of Carnegie Mellon University in the United States said: they are the best toys on the market. Josett is a robot expert, mainly engaged in robot design, programming and manufacturing

magical snake robot

when josett was a child, he was interested in anything that could move cars, trains, animals. He put the motor on the small toy car to make them move. Later, in high school, he built a mobile robot similar to a small car

in order to continue to engage in robot research, josett constantly consolidated and improved his leading edge in related fields and studied computer science in universities. But when he was a graduate student at the California Institute of technology in Pasadena, josett found that his colleagues were working on something cooler than a remote-controlled car, a robot snake. Some robots can only move forward, backward or left and right. But snake like robots can twist in different directions, and can move forward on many different terrains. Josett concluded: robot snakes are much more interesting than cars

the robot snake developed by josett and his team can twist in different directions. These snake shaped robots can roll forward, slowly climb onto someone's legs, and even swim

after starting to work at Carnegie Mellon University, josett and colleagues began to develop their own snake shaped robots. Typical snake robots are interconnected by metal containers, each part of which is composed of motors and electronic components. Josett's team programmed the snake robot to move like a real snake, such as sliding and moving slowly ldquo; Lithium battery equipment, especially power equipment. This kind of robot will also move in a way that does not belong to snakes, such as rolling. Josett's snake robot can climb over the grass, swim in the pond, and even climb the flagpole

these robots have another feature: they can move in a narrow space. Josett said: snakes can enter places we can't reach, so this kind of robot can also be used to save lives. For example, after the earthquake, snake robots may be able to help people find people trapped in collapsed buildings from existing projects. It is very dangerous and difficult for rescuers to search those buildings. However, with the help of snake shaped robots equipped with cameras, rescuers can search for survivors from a safe distance from the ruins. With the help of search and rescue personnel, josett tested his robot at the rescue personnel training base called disaster city in Texas

but josett wants to know whether his snake like robot is also useful in medicine. For some heart surgery, the doctor must open the patient's chest and cut open the sternum. And the recovery of these operations is very painful. If the doctor could complete the operation by opening a small hole in the body and sending a slender robot snake, what would the result be? Josett's team is currently working with Marco zenati, a heart surgeon at Harvard Medical School, to study this idea

zenadi practiced using the robot on a plastic model of his chest, and then tested the robot on a pig. He injected anesthetics into the pigs so that they wouldn't feel anything. Then, he dug a small hole under the chest of the pig and inserted the head of the 30 cm long snake robot. Using the joystick, zenadi moved the robot to the back of the pig's heart. Then he passes the surgical tool through the robot's body and uses this tool to perform surgery on the animal's heart. Medrobotics, a Boston company, is now adjusting the technology for patients undergoing surgery

snake shaped robots can even be used to search for ancient cultural relics. Josett is exploring the possibility of sending robots into Egyptian archaeological sites, which used to be too small or dangerous for people to enter. Snake shaped robots equipped with cameras can show scientists what is inside, and may even find artifacts. Josett said: even after working with the team for 15 years, I still won't get tired of watching our snake robot movement

follow the leader

Maurizio porfiri, a mechanical engineer at the New York University Institute of technology, is also making robots similar to animals. But he has a different goal, that is, to help real animals. Boffini's team created robots that looked like fish. These researchers hope that their machines are persuasive enough so that real fish can accept robot fish as part of their group. In this way, the robot can guide the fish away from dangerous places, such as oil spill areas

boffin and his team designed and manufactured robots that imitate fish

boffin has always been interested in animals. When he was growing up, one of his favorite activities was going to the zoo. But boffini also likes robots seen in Japanese comics. So when he began to build his own laboratory, he decided to combine these two interests

scientists have known that fish like to swim in groups. The leader of the fish will create a trail, that is, in the deep waters where they leave chaos. Since swimming in the wake of another fish consumes much less energy than swimming alone, many fish will follow the leader and thus form a school of fish. In order to find out whether fish will accept the leadership of robots, boffini's team must first build fish shaped robots. Its flexible tail can swing back and forth, pushing the robot forward. Boffini explained that in order for real animals to interact with the device, fish need to see something that looks like them, such as swimming like them

researchers put the fish shaped robot in the laboratory canal and let the tail of the robot fish flap the water at different speeds. Then they added real fish, such as goldfish, and measured the time goldfish spent near the fish shaped robot. They also observed whether the fish swam in front of or behind the robot fish. If the robot fish's tail doesn't swing, the goldfish doesn't pay much attention to it. But when the tail of the robot fish moves at a certain speed, the fish begins to swim behind it. Boffini believes that fish will follow robots because it will make them save more energy

however, not all fish follow robotic fish, and boffini's team is now trying to find out why. Engineers may need to use several different robots, each attracting or repelling different fish to attract as many followers as possible

boffini's team is also developing a robot submarine to help captive animals. Submarines with propellers can harm animals. Therefore, researchers are developing a safe submarine with all its moving parts inside. Aquarium trainers can use robotic submarines to play with animals such as seals or walruses. For example, animal trainers can attach food to submarines and let animals prey, just as they prey on prey in the wild

robot with personality

when Maya mataric was in high school, she wrote a computer program that could talk to someone. The user can enter a message into the computer, and the program will then display a reply. Now, a roboticist at the University of Southern California in Los Angeles is leading a project called social assistant robots. These devices can speak, gesture, and walk around

mataric's team is designing a robot that can help people with communication difficulties practice social skills

mataric hopes her robot can help people with diseases or physical disabilities. For example, people with Alzheimer's disease will have memory and brain function problems, and may need the help of psychological practice. People who try to recover arm function after a stroke may need encouragement to continue doing beneficial exercises. However, since there are not enough people to provide all kinds of help, technical intervention is needed

in a study, matarik's team tested the recovery of stroke patients assisted by robots. A stroke is usually caused by a broken blood vessel in the brain or a blood clot that prevents blood from flowing to the brain, and a small number of cells die during a stroke. So later parts of the body (like arms) may become fragile or numb. Patients must exercise constantly to recover their functions. However, these exercises may be difficult and unpleasant

matarik and her colleagues program knee high robots, urge patients to exercise, and then monitor patients' movements. If the person actively uses his or her arm, the robot will give encouraging words. The team tested the robot on six stroke patients. When robots are present, patients tend to exercise longer and follow instructions than when there is no prompt

next, researchers tested whether the robot's personality affected people's reaction to it. Robots can approach patients directly, speak loudly and make powerful statements, such as you can! At other times, researchers will let robots act in a more shy way. Users should conduct a series of checks on the fatigue testing machine every day before starting operation. During this time, the robot kept a certain distance from the patient and gently put forward some suggestions. For example, I know it's difficult, but remember it's for your own good

in this study, healthy adults exercised with their weaker hands. These tasks are similar to those of patients trying to recover from a stroke, such as moving a pencil or reading a newspaper. The research team found that when robots have similar personalities to themselves, people practice their tasks longer

matarik is also studying robots to help children with autism. Children with these diseases have difficulties in communicating and interacting with people. Matarik hopes that robots can help these children practice social skills. The advantage of robot over human is that it never feels tired, depressed or angry

matarik's team designed and programmed the 1-meter-high humanoid robot bandit, which can make noise, move around and blow bubbles. In one study, researchers observed how eight children with autism spectrum disorders responded to bandit. Some children seem to like this outfit
