Robotics



What the Robotics is all about:

― History of Robotics in Japan and my personal contributions to its progress ―



Origin of Robots


The word "Robot" stemmed from a Czech word "robota" that means slaves. This word first appeared in a drama called "Rossum's Universal Robots (RUR)" written in 1920 by Karel Capek (1890-1938). In its story, robots created by humans gradually start revolting to the human masters. However, the ideas of such robots (androids) existed far before Capek. The Irias (Iriad) written by Homeros (Homer) in sometime around the 10th century B.C., now being recognized as one of the origins of European literatures, is said to be the work in which the robotic creature first appeared. Since the Irias, there have been numerous works that dealt with autonomous machines with a human-like behavior or with a superhuman power. The RUR was one of them.



Rise of Robotics




It was mid 1960s when these robots in one's imagination turned to our realistic subject of the technological developments. At that time, our dreams were the realization of automated machines that can work on our behalf, with a higher performance, even in part, than humans. In those days, I was studying mechanical arms, and developed an electronically-controlled servo-manipulator for handling radioactive materials. To further realize new robotic machines, it seemed that the vision system was one of the most important and yet difficult subjects to be studied. Shortly, I had a chance to stay at the University of Illinois, USA, as a visiting staff, and there I started to work on physiological vision systems by using cats and dogs. After coming back, I started to design electronic machine vision systems, and developed a computer-controlled vision-based intelligent robot system called HIVIP Mk.1. This robot system was demonstrated in the public eye at the Hitachi's Technology Fair held in Tokyo Museum of Science in 1970, and was well received with a favorable response. Nowadays, these achievements in my past became a part of my dear memories.

Besides these works, there were of course a few epoch-making activities in other organizations at that time. With the success of these pioneering efforts, industry was encouraged to proceed to the development of new types of practical robots and systems. Many industrial robots were prototyped and then put into use in production lines one after another. In addition, real-time machine vision technology was also created and was applied to various industrial lines typically for semiconductor assembly, thus revolutionizing the production style completely.


With the progress of technology, the word "robotics" was also created as a natural result, and has been used to cover all the scientific and technological research areas relating to robots and autonomous systems.



Birth and Growth of RSJ



In such circumstances, researchers working in academy, industry and government gathered together in 1983 to start up a new society. This was the birth of the Robotics Society of Japan, and the prospectus at its foundation emphasized the importance of:
       1 Cooperation of researchers in various fields,
       2 Promotion as a total science, and
       3 Mutual enlightenment among researchers and their competitive self-improvement,
The starting members were 761, and as one of these originators, I delivered a special talk at its first general meeting. The birth of this society and the outline of my talk were reported in Nikkan Kogyo Newspaper on January 29, 1983.
Since then, the Robotics Society of Japan (RSJ) and its members played an active part in pursuing the technological advancements. By the cooperation of academy and industry, many robotic technologies were created. These included the technologies for SCARA-type high precision assembly systems, for computer-controlled intelligent industrial robot systems, and for high-speed industrial machine vision systems. Through the application of these technologies to the production automation, the RSJ and its members greatly contributed to the technological progress in Japanese industries and also to the worldwide evolution in manufacturing engineering.

In addition to versatile industrial robots for machining, welding, assembling, and painting processes, the robots developed in those days were for searching flaws in pipes, for feeding and placing electronic parts, for constructing buildings, for boring tunnels, for setting up underwater equipment, and for cleaning airplane surfaces. Furthermore, robots walking on a wall, robots for security patrol, and even robots for making Sushi were also challenged and realized in those days. As a result, Japan became one of the leading nations in robotics in 1980s, and the number of working robots in Japan exceeded 300,000 in 1990.
Beside these, humanoid-type robots were also studied, and the examples were WABOT-1 in 1973 and WHL-11 in 1985. These preceding technologies in Japan made it possible to develop novel biped walking machines afterwards. ASIMO in 2000 by Honda was one typical fruition. Nowadays, new applications of biped robots, typically to entertainment and rescue fields, are also being intended.
With the progress in technologies, the RSJ has also made a steady growth, and it has more than 4000 members presently. In 2002, it celebrated its 20th anniversary and held a commemorative meeting at Osaka University. Through the efforts of its members during the past 20 years, the RSJ seems to have consolidated its position as one of the world’s leading scientific and technological societies. At the time of 20th anniversary, I was serving as the President of the RSJ, and one of my messages appeared in Advanced Robotics, an official English journal of the RSJ, is again shown below for your reference. By commemorating this anniversary, revision of RSJ logo was also planned and was enforced as of Jan. 1, 2004. The new logo of the RSJ is also shown below.

The purpose of the RSJ has been to contribute not only to the progress of Science and Technology, but also to the prosperity of industries through pursuing advanced research and popularizing the resulting knowledge. To this end, the RSJ publishes journals both in Japanese and English, and holds a variety of technical courses and meetings. Through these activities, exchange of knowledge among members and dispatch of new ideas and research results to outside communities are being intended. A typical example of the RSJ activities is an annual conference for research presentation, and its history is indicated in the following table. In this table, the number of members and the names of presidents at each term are also shown for better understanding of its history. In this annual conference, awards are given to authors and contributors, for their excellent papers, for their excellent presentations, and for their excellent developments of robotics-related products and systems. A medal for the excellent paper award is the same as the one that was brought to the space in 2000 by a Japanese Astronaut Koichi Wakata, a member of RSJ. The medal traveled 8,500,000 kilometers by rounding the earth 202 times, and was returned to the RSJ directly from Mr. Wakata together with the certificate of authorization as a NASA official flight kit.

IROS



One important service of the RSJ is to hold international meetings for exchanging ideas and knowledge with other parts of the world. The IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) is one typical example, and was started in Japan in 1988 by cooperating with two other organizations, SICE (Society of Instrument and Control Engineers, Japan) and NTF (New Technology Foundation, Japan).  As can be seen in the history of IROS indicated in the following table, meetings were held mainly in Japan before it was broadened to other part of the world.

Progress in Robotics



Thus the robotics in Japan has been enjoying its prosperity as a result of long-term challenges of academy and industry in the past 50 years. The history of research and developments in robotics during the past 50 years are summarized in the following chronological table. In this history, I and my colleagues at Hitachi could also make big strides in investigating and progressing robotics, and could support the basis of Japan's robotics together with other leading organizations. History of Hitachi robots is also listed below. These Hitachi robots are of special importance to me and are now a part of my unforgettable memories.



Future of Robotics



One of the important future missions for both the robotics researchers and the RSJ itself is to promote further progress in technologies, related especially to speedy locomotion, dexterous handling, and intelligent decision-making based on self-learning of skills and efficient recognition of outside world. These technologies are anticipated to be unified through the aggressive cooperation of researchers and engineers in academy, industry and government, by bearing in minds the versatile applications such as for environmental, medical, welfare, crime prevention, calamity prevention, rescue, manufacturing, traffic, logistic, and spatial use. As an ultimate goal, the robotics research should be directed towards the realization of automated intelligent society, where people can enjoy their productive, efficient, but still calm, safe, and stress-free human lives with the extensive supports by robotics technologies.

I especially like to expect young researchers to be one of the world leaders in robotics. It will be important for such robotics leaders to continually present dreams and hopes to the public, to brush up individual technologies into practical and systematic technologies, and to advance them as a trans-disciplinary science and technology for the broader applications towards harmonious future society.
