Teaching Robot – ‘Cô giáo’ robot dạy tiếng Anh của sinh viên

TTO – Giao tiếp tự nhiên, bài giảng thực tế, truyền đạt sinh động khi tích hợp hình ảnh, video và những bài tập với độ tương tác cao… ‘cô giáo’ robot gây thích thú khi dạy tiếng Anh cho học sinh.

Robot này là sản phẩm của Nguyễn Trần Thanh Phong – sinh viên năm 4 trường ĐH Sư phạm Kỹ thuật TP.HCM sau nhiều tháng lên ý tưởng và tiến hành nghiên cứu.

Trước đây, cũng nhờ vào ý tưởng này, Phong nhận được một chuyến tham gia trại hè Sáng tạo kỹ thuật ở một trường đại học tiểu bang Michigan, Mỹ khi các nhà khoa học cho rằng robot có khả năng ứng dụng cao trong tương lai.

“Tôi từng đi dạy tiếng Anh và rất thích học tiếng Anh. Tôi cũng rất mê robot và sáng chế. Vậy là tôi nghĩ: sao không thử kết hợp hai thứ ấy với nhau xem sao?”, Phong chia sẻ.

Để ‘cô giáo’ robot có thể đứng trên bục giảng, Phong phải viết nhiều chương trình khác nhau, bao gồm bài giảng, bài tập và nhiều đoạn thoại giao tiếp với học sinh…

Nhờ phần mềm xử lý ảnh, robot có khả năng nhận diện khuôn mặt, có thể điểm danh hoặc gọi tên học sinh khi phát biểu.

Khuôn mặt robot được lập trình biểu thị cảm xúc tùy theo câu trả lời và thái độ của người học. Những cử động tay và thân thể của robot cũng giúp học sinh hứng thú hơn.

Nhờ vào một màn hình lớn ở bụng, robot có thể trình chiếu những bài giảng trực tiếp cho học sinh.

Trong tiết học, khi muốn giao tiếp hoặc trả lời câu hỏi, các em sẽ sử dụng micro được kết nối bluetooth hoặc có thể chạm vào màn hình tương tác của robot.

Hiện nay, một bài giảng được Phong thiết kế bao gồm các phần điểm danh, kiểm tra bài cũ, học từ vựng, ngữ pháp kết hợp với những bài tập tại chỗ… giúp học sinh có thể dễ dàng tiếp thu và ôn tập kiến thức mới tại chỗ.

Tuy nhiên, sản phẩm chỉ mới được thử nghiệm trong một không gian hẹp với số lượng học sinh hạn chế.

“Trong tương lai tôi sẽ nâng cấp và hoàn thiện sản phẩm của mình. Robot sẽ dạy ở nhiều nơi hơn và có thể tương tác tốt hơn. Tôi rất muốn có một trung tâm tiếng Anh chỉ toàn robot đứng lớp”, Phong hào hứng.






Robot for Kids – BETA Robot Nannies

If you’re a parent, you probably know how expensive hiring a nanny can be. To help out, companies are coming out with high-tech alternatives. Beta robot is a roving robot that roams around the home to assist with tasks such as waking up the kids when it’s time to get ready for school, telling bedtime stories, and singing the children’s favorite songs. When parents are not home, they can view their children through the robot’s built-in cameras, which they can monitor via a mobile app.






Robot Massage

This project is described the massage robot working and acting on the body back with pressure by automation. The massage robot will offer a more affordable and user-friendly alternative with the same benefits as the massage by the therapist. The study investigated the role of effective massage head of robot in the interaction between human and robot. Through a process of design and controlled user evaluation, we examined the cooperation between robot and human as well as the physical influence of affective contact. The system scans to perceive and give motions and touch through elastic and vibration contact. We detail the design of the massage robot, which imitates massage experts with complex operations, then was enhanced through intelligent autonomous.

In the Eastern countries, acupuncture and acupressure are very popular and no one can deny their positive aspects. They help people relax and feel comfortable after a long day working. Besides, the advantages of kneading on human point are discovered by experts through their long-time working in this field. However, the current method that chiefly uses the human resource still has some defects. First of all, a human can do no more than he can, working in a long period of time can make therapists exhausted and the efficiency also decreases dramatically. Secondly, privacy is the considerable problem. Being looked and touched by a stranger is not a good experience. The most important thing is the contagion. Along with the development of medicine, viruses also increase considerably. The viruses can be spread through touch on the skin. All aforementioned reasons make the traditional method become outdated and risky as ever. Knowing that need, a massage machine is oncoming. It can be controlled by some buttons as well the remote control. Someone think that is convenient but the others argue that it is complicated and not suitable for the old and children. A totally automatic robot is in need.

Massage robot systems are performing and expected to perform healthcare missions. It is difficult to develop an intelligent robot, which performs point and massage tasks autonomously on human back. Current massage technology makes necessary to rely on the human operator for providing overall task contact and interaction, and for handling special situations. The benefits of automation of a massage robot have already been proved, which is operated to perform complex tasks. There are many advantages: first, the touch of human hands is replaced by the robot massage head; second, the control of the movements and trajectory can have greater resources available based on AI; third, the massage by robot permits to reduce workload; and forth, robot massage removes social evil to perform interaction between two people, etc. Hence, using robot for massage seems very attractive, but on the other side there are some important drawbacks or limitations that must be overcome: (i) human-robot interaction; (ii) determination of human points and massage lines being suitable to health care; (iii) lack of feedback signals with difficult control in operation. Under such a condition, special attention should be paid to contact forces when performing contact task with a robot on the human back. Therefore, the robot should be controlled autonomously with compliance feature. Compliance is useful to cope with the error caused by an imperfect model. Note that some sort of compliance feature on the manipulator, either active or passive, is effective for contact task.







The number of elderly people are growing very fast all around the world. As age increases the occurrences of disabilities are increasing which means they are not as active as young people and they require more assistance from their family members or their caregivers in places such as homes, nursing homes or hospitals. As the number of elderly is growing, the number of people living in long term care institutions are growing. According to the goals and standards of the health care system (WHO), this population should receive adequate service to be able to have a happy and healthy aging. The fast growing need for responding to these service requirements will have a great impact on the health care system. Nowadays many research groups are conducting their work to find different possible solutions for different kinds of people, environment and service by using the latest available technology.

Many elderly people are struggling with accomplishing even the most frequent daily activities. Today, various intelligent, and non-intelligent, machines and robots have been developed to meet the needs of the elderly and people with upper limb disabilities or dysfunctions in gaining independence in eating, which is one of the most frequent and time-consuming everyday tasks. However, in almost all cases, the proposed systems are designed only for the personal use the Western food and nothing effort to design a  device for Vietnamese food has been previously made.
The elderly and their feeding requirements in environments such as nursing homes with many elderly residents dining together at least three times per day have not extensively been researched before. This, the unavailability of Vietnamese food feeding systems in the market, and the lack of related research motivated this project.

The aim of the thesis has been to make individuals with disability in arms, who have been fed during meals, completely or partially independent by use of the self-feeding device. It describes a self-feeding system designed to increase the independence of a person who is unable to use their arm for self-feeding. It is FeedBot, a highly integrated and compact service robot with manipulator and food index tray. FeedBot is an intelligent device for disabled people in the home health care is self-feeding manipulator especially to Parkinson patients, who have difficulty to feed the foods while eating. In particular, FeedBot combines the best of available technology including a 2 DOF light-weight  manipulator and an index tray. It operates with a food tray and a manipulator to bring the foods from tray and feed to disabled people as Parkinson patients. The self-feeding system is operated autonomous by itself and sent food’s data and relative information to monitoring computer based on Internet. Besides, the tool of management can analyze the data according to the nutritional standards, and controller control movements of manipulator and automation tray based on health situation and needs of patients.
