People's needs are the future development direction of educational robots. On the whole, students, teachers and parents have put forward more needs, and a few of them have already been reflected in some educational robot products.
Most of the requirements have not been effectively implemented. The demand for educational robots proposed by students, teachers and parents represents the future direction of educational robots.
Special education robot exploration road
1, the key technology of educational robots
Three key technologies for the future development of educational robots:Human-computer interaction, machine vision, situational awareness.
Human-computer interaction.Human-Robot Interaction is mainly about the information interaction or dialogue between humans and robots. It is a comprehensive interdisciplinary subject closely related to cognitive psychology, ergonomics, linguistics, sociology, computer science and so on. . Human-computer interaction is the cutting-edge and key technology in the era of intelligent service robots. As a typical application of intelligent service robots in the field of education, educational robots are also inseparable from human-computer interaction technology in the design and development of educational service functions.
Machine vision . Machine Vision is a technology that uses machines instead of human eyes to make various measurements and judgments. The development of machine vision technology can create vision systems for robots that, like the role of the human visual system, enable robots to react to their surroundings in an intelligent and flexible manner. In the field of education, how to identify teaching scenes and develop more adaptive robots should be the focus of educational robot manufacturers.
Situational awareness.Context Awareness is the use of various complementary information at the time to make decisions when making decisions to ensure that the right decisions are made to support dynamic business and IT environments. In some areas of research, contextual awareness is used as a way to share, reflect, and collaborate. From an educational point of view, robots need to complete different types of educational services in a dynamic, unknown, unstructured and complex educational environment, which puts higher demands on the contextual awareness technology of educational robots. .
2, the status quo of educational robot design
The design and development of the educational robot body is still in its infancy.The ontology of the educational robot has not yet formed a systematic design plan, and no specifications have been formed in terms of architecture, bus, communication, interface, and standards;
In addition, the ontology design of educational robots has not yet formed a scale effect similar to computers and mobile phones; in addition, the content of basic research is only sporadically appearing in relatively independent technical links, which is insufficient to support the breakthrough of the entire industry. Sexual development.
Application scenario analysis is the starting point for educational robot design . There are two development orientations in the design and research of educational robots: one is scientific research oriented and the other is product production oriented. Regardless of the orientation design and research, in order to educate robots to enter the application practice of educational services, it is necessary to analyze the application scenarios first, and then determine the functions that need to be implemented in the scenarios according to the needs existing in the application scenarios. And possible implementation methods.
Intelligence is the focus of educational robot design.In the future 10 year, artificial intelligence will become the most disruptive technology, and upgrading the service experience of intelligent technology will be the focus of educational robot design. The intelligent representation of educational robots is supported by technologies such as human-computer interaction, machine vision, and situational awareness. It should have the attributes to actively meet the various educational needs of different groups of people.
Modular design is the trend of educational robot body design.Compared with electronic devices such as computers and mobile phones, the body structure of the robot has not yet formed a specification. The main feature is that the design of the machine components and hardware needs to match the shape of the robot. The modularization method is used to design the educational robot into multiple organic modules, and the necessary communication protocols and interfaces are used to transmit information and control commands, which is more suitable for the ontology design of educational robots.
The stacking method is usually used in the intelligent design of educational robots. On the one hand, the intelligent nature of educational robots is the application of artificial intelligence, which contains a variety of intelligent components, and the various intelligent components have not yet formed a system, stacking intelligence is currently a more effective method. On the other hand, the intelligence of the robot is equivalent to the computing power of the robot to a certain extent, and the intelligent computing operation of the educational robot contains too many computing requirements. One way to improve the intelligence of the robot is to design each AI function for the robot. Modules that distribute computing power requirements across modules to reduce the stress on the computing power of the main CPU. From a certain point of view, the method of using the modular structure of distributed multi-CPU to enhance the computing power of the robot is also a method of stacking intelligence.
Educational robots need to develop more education-applicable intelligence.Although educational robots do not replace the teaching functions of teachers, if educational robots are more qualified for educational services, on the one hand, it is to improve teaching efficiency, on the other hand, it needs to make breakthroughs in function. In this process, educational robots need to have more powerful functions in the classroom and family, which are the most reflective of the characteristics of educational services, to show their possible application value.
The status of the educational robot industry: Seven-layer chain that goes hand in hand
1, educational robot industry chain framework
By investigating the status quo of the manufacturers related to the educational robot industry, and aiming at the future development trend of the educational robot industry, the 7 layer industrial chain framework of the educational robot is based on the mature development of the tablet industry chain, as shown in the following figure.
Compared with industrial robots, educational robots are more complicated in form, composition and function. In addition, they are still in the early stage of entrepreneurial exploration. The enterprises in the 7 layer of educational robots are not strictly upstream and downstream. Businesses have multiple roles at the same time.
In the 7 layer industry chain framework of educational robots, "AI chip manufacturers" provide artificial intelligence chips required by robots, which is the basis for robot intelligence; "hardware manufacturers" provide motherboards, control boards, and steering gears that make up robots. , sensor, communication module, chassis moving mechanism, power supply and other components manufacturing, assembly and testing; "system platform developers" to develop and manage software and hardware resources system platform, providing the most important natural user interface for human-computer interaction (Natural User Interface (NUI); "Application Service Provider" develops various educational service function software including teaching and learning courses based on the system platform, and is provided by the "content provider" in the teaching and learning process. The “system integrator” is responsible for integrating market requirements and software and hardware functions into one final product; “channel vendors” deliver products to end consumers or users through various entities and virtual sales channels.
