How to treat the movie Hero 6 from a scientific perspective?

Disney's latest animated film "Hero 6" describes a virtual city "Old Jingshan", which combines San Francisco and Tokyo. This paper tells the story of Xiaohong, a 14-year-old prodigy who is proficient in robotics, and Dabai, a robot health assistant.

Disney movies at the end of 20 14 can be said to be a dark horse at the Hollywood box office. From the perspective of a technology house, they hit two hot spots in American science and technology: robotics and medical and health fields. These two markets are also hot spots in the field of science and technology in China. One is expected to reach 10 trillion in 2020, and the other is 8 trillion. Dabai is not only perfect, but also close to realization.

First of all, a brief analysis of Dabai-the balloon shell is somewhat childish, but the carbon fiber skeleton, lovely design, and the ability of voice recognition and body sign scanning are all very reasonable and mainstream designs. Dabai is a collection of three major technology industries: mobile medical care, robot manufacturing and artificial intelligence.

Let's talk about mobile medical care first.

Now the more common name is mHealth. At the 20 10 mobile medical summit, the United States defined mhealth-providing medical services through mobile devices. With this in mind, the mobile robot is clear and does conform to this definition.

The original full name of mobile medical English is "emerging mobile communication and network technology in medical care", which is translated as "emerging mobile communication and network technology in medical care industry". Therefore, the fundamental reason for the rise of mobile medical care is the development and popularization of communication and network technology, the decline of cost and the popularization of equipment, especially the massive deployment of smart phones, which led to the outbreak of mobile medical care. At present, mobile medical care is still in the middle stage of the development of communication technology dividend.

Logically speaking, the popularity of mobile devices has contributed to the mobile medical industry. So whether the robot industry is mature or not is an indicator of when Dabai made it. Dabai is really not far from us. The cost of doctors and nurses who are accompanied around 24 hours is extremely high, but if they are replaced by robot health assistants, the cost will indeed drop to an incredible low.

Both the United States and Japan are making medical robots with their own characteristics.

Case study of medical robots in the United States and Japan

United States of America

InTouch Health, an established mobile medical company, has connected 654.38+0 million communities and clinics in the United States. Their strategic investor, iRobot, the top robot company in the United States, has made a series of robots for IntouchHealth, which they call telemedicine robots.

These robots can play the role of doctor's body body double in community hospitals, patients' homes, wards and other places. The doctor who controls the robot remotely can track the patient's life for a long time, supervise his living habits and provide him with a more thorough treatment process.

In addition, five major medical institutions in the United States, DigitalHealth, are also making their own telemedicine robots.

The U.S. Army Center for Telemedicine and Advanced Technology commissioned VECNA, a robot company located in Massachusetts, to develop an automatic battlefield rescue technology, which eventually evolved into a battlefield-assisted evacuation robot (BEAR) to realize a complete set of battlefield rescue functions such as rescuing and transporting the wounded.

Japan

Robot XXI invented by Waseda University in Japan is different from the telemedicine direction of IntouchHealth. The most important goal of the 21st century is to simulate human nursing staff. The robot's hand tries to imitate human beings. In the initial demonstration, it can already pick up the habit and squeeze out ketchup. It is expected that 20 15 will be put into use to take care of the elderly and patients. The disadvantage is that it is expensive-about 30 million yen.

Toyota -20 1 1 released four kinds of robots used in the medical field, which are used to help people with disabilities due to lower limb paralysis, including "independent walking assistant", "walking practice assistant", "balance practice assistant" and "helping to move". Yoichi Inoue, director of Toyota, said: "With the increasing number and aging of children, assistant robots for nursing and medical care will become more and more important."

An Chuan —— On 20 14, a rehabilitation robot was released to help patients with limb rehabilitation. But their products are more automatic modification of the original rehabilitation equipment, which is more ergonomic and improves the efficiency of medical care.

HAL—— the product of CYBERDYNE of Tsukuba University, Japan. HAL(HybridAssistiveLimb) is the world's first wearable power assist system equipment certified by ISO 13482, and its medical improvement has passed the EU CE certification as a medical equipment. Designed to help patients with lower limb muscle atrophy. When you want to stand up, walk, stop, lift your legs and go down the stairs, it will help you properly.

You can call HAL a wearable robot. From the abbreviation, we can see the meaning of paying tribute to Kubrick 200 1 Space Roaming. The robot in that movie is called Hal.

Creating AI

How strong is the artificial intelligence of medical robots? It may be that science fiction movies have too much imagination of artificial intelligence, from the king of extinction to Jude Law, whose artificial intelligence is almost perfect. But in fact, artificial intelligence has already existed in everyone's life, and these carefully designed "software" are designed to help you improve efficiency. Maybe the artificial intelligence of medical robots can't replace doctors yet, but there must be a way to make you healthier.

Dabai's biggest task is to scan the target users through cameras and other equipment, perceive their signs, health data and emotions, and then take measures to carry out health care. In the animation, the hero, A Hong, was hugged twice by Dabai, once because his brother died and his mood was scanned by Dabai; Once, I fell into the water, and Dabai noticed that my body temperature dropped, so I hugged. Dabai also regulates his temperature and raises Ah Hong's body temperature. Think about it. Isn't this a lot like NEST? In fact, NEST was spotted and acquired by Google with Internet of Things, artificial intelligence and machine talents.

Here are some products of companies that can make Dabai.

Jibo-as a representative of home applications, it is not so intelligent compared with DeepMind and IBM's Watson, but they have an important function-voice interaction and emotion recognition. JIBO's system uses NLP (Neurolinguistic Programming) to understand commands and even daily conversations. Users and their families can be identified, and different voice interactions can be carried out through different users and different emotions of users.

NEST-Americans' habit of using thermostats can learn the user's sensitivity to temperature, and adjust all devices connected to Nest through the change of ambient temperature through the Internet of Things, so as to achieve the room temperature and humidity that users like.

Deepmind-this is the name of the artificial intelligence company that Google acquired after it acquired NEST. They were merged into Google's oldest search team and given the task of doing knowledge. Is it high? That's because DeepMind's deep learning algorithm enables their artificial intelligence to learn. Previously, at CES, they showed how DeepMind "played" a brand-new game. A doctor teaches it several times, and his robot will diagnose and treat it. Does this future look good?

Robot vision

In addition to satisfying automatic artificial intelligence, Dabai's scanning ability for human body is also essential, and such black technology has reference significance in reality. This is Microsoft, which recently took out such a magical thing as Hololens. Their KinectOne (computer version called KinectV2, here referred to as Kinect2) is the best visual equipment for Dabai all year round.

Kinect 2-Microsoft chose TOF instead of structured light (Kinect 1 technology). At present, muscle stretching, body surface temperature and heart rate can be identified-these are all data needed in medical care. The principle of realization, taking temperature and inflammation as simple examples, is to identify temperature by intercepting the color of human surface, and the accuracy is still evolving.

There are also teams in China that are using ordinary cameras and OpenCV related technologies to complete similar tasks-Diankang Technology, which claims to be able to measure blood pressure with cameras, but it has not been verified.

What should we do?

As a pioneer team in the field of home service robots and telemedicine robots, we have made two kinds of nursing robots based on open source ROS (robot system), mainly for children and the elderly. The core function is similar to IntouchHealth, that is, remote control.

In addition, in order to make the target users accept the robot, we put a bionic pressure sensor and a natural language synthesis chip inside the robot, so that the robot can feel at least 10 touch and interaction. Combined with natural language processing system, the robot can synthesize sounds familiar to users, instead of robot sounds, and realize the functions of reading text information and voice interaction. For example, the elderly with poor eyesight can synthesize their children's voices, read short messages to the elderly, remind her to take medicine and so on.
