Practical Robotics and Mechatronics Marine, Space, and Medical Applications by Ikuo Yamamoto | PDF Free Download.
The world is experiencing the beginning of a revolution in robotics and mechatronics. A key part of this revolution is integration with IoT (Internet of Things), this networking of robotics and mechatronics will represent significant market opportunities.
The author engages in developing technologies using IoT-based intelligent robotics using several effective applications as examples.
The successful development of practical robotics and mechatronics must begin from consideration of IoT and/or the M2M (Machine To Machine) interface.
The author has developed many world-class practical examples of robotics and mechatronics during his 30 years of experience as an engineer and a professor. The author’s experience comprises working with Mitsubishi Heavy Industries Ltd.
(20 years), JAMSTEC (3 years), and as a professor at Kyushu, Kitakyushu, and Nagasaki University (10 years). Most of the robotics and mechatronics developed to continue to be used safely.
Such an experience of development inherently creates new ideas for robotic applications. Based on the author’s experience, important ways of thinking, and technologies essential to produce successful robotics and mechatronics are summarized in this book.
The author hopes that this book can provide fruitful hints for developing new robotics and mechatronics that will lead to new and successful business opportunities.
There is a high demand for developing robotics and mechatronics around the world. The market for robotics and mechatronics continues to expand and is expected to be an increasing business field.
The market needs practical robotics and mechatronics, which meet societal demands. How can we develop new practical robotics and mechatronics?
The author has developed practical robotics and mechatronics during his 20 years or so at Mitsubishi Heavy Industries, Ltd., and has invented many products, such as a 10000-m operating depth capable unmanned remotely operated vehicle (ROV), called Kaiko; a manned underwater vehicle, the Shinkai 6500; a hydrofoil catamaran called Rainbow;
an air cushion surface effect ship, the Techno Super Liner; the intelligent ship, the Super Joy; a dynamic positioning system (DPS) of offshore platform, like the bridge construction vessels UMASHIMA and CHIKYU; a riser entry system, robotic fish; the B787 main wing, a regional jet.
The author was the project leader of the autonomous underwater vehicle (AUV) Urashima, which established a world record for autonomous continuous cruising in 2005.
In addition, as a university professor for over 10 years, the author has developed intelligent robotics such as robotic fish, a multirotor aviation system, medical robotics, and space robotics. Particularly – true story! – one of the author’s robotic fish swam in space.
This book can provide hints for solutions to developing new robotics and mechatronics which are intelligent and practical. Robotics is defined as ‘an intelligent machine system which consists of sensors, actuators, and a controller’.
If robotics as compared to humans, the relationship of sensors, actuators, and a control device can be summarized as shown in Figure 1.1.
Sensors are the devices that feel or sense the outer and inner states of the robot, similar to the eyes, ears, nose, and pressure/temperature points of the skin in a human body. Actuators are the devices that actuate parts of the body, just like the hands, feet, and mouth.
A controller is a device that makes decisions according to the sensor information and other data and gives commands to the actuators to move (or stop), as in the brain of a human.
Mechatronics is defined as ‘mechanics with an electrical circuit’. Mechatronics is originally a Japanese-made English word, which is a mixture of mecha(NICs) and (elec)Tronics. Robotics is composed of mechatronics, as shown in Figure 1.2.
Robotics and mechatronics consist of many fundamental technologies, such as mechanics, electronics, electrical engineering, and information technology.
Fundamental technologies sometimes come from economics, medicine, agriculture, fishery, literature, and other scientific subjects. The author refers to such technologies as ‘universal knowledge’, where ‘universal’ provides the root word of ‘university’.
That is, the knowledge important for robotics and mechatronics are subjects that students learn during their undergraduate terms at university.
The basic procedure to create new robotics and mechatronics can be summarized as shown in Figure 1.3. Fundamental technologies and their integrated systems produce seeds for robotic and mechatronic inventions.
Customers outline their needs, and the result is the development of new robotics and mechatronics.
It is important to develop new robotic and mechatronic mechanisms to meet customers’ requests and to be creative and highly functional. In addition, the Japanese methods of manufacturing are well suited to the development of new robotics and mechatronics.
There is a Japanese word, Fekkai, which means ‘interference and meddlesomeness from goodwill’. Development of robotics and mechatronics usually involves group work, and it is important that each engineer is not only professional in one element of technology but also mindful of other fields of technology, and entirely covers all fields of robotic and mechatronic development in the group.
