The word mechatronics appeared for the first time in Japan was first introduced by the senior engineer ‘Yaskawa’ in 1969, the word mechatronics is a combination of two parts "mecha" of mechanisms or mechanical and "tronics" of electronics. Mechatronics is synergistic integration of many engineering divisions; it gathers the following engineering divisions: mechanical engineering, electrical, electronics, computer science, and control. Robotics technology is considered to be one of the most new born technologies from Mechatronics. As if you need to construct a robot, you will need to fully understand many engineering basics from mechanical, electronics, control and programming. This book shows a different robotics systems and smart machines. PLC and Microcontroller programming were used to program some of those robots. Systems and smart machines on this book were designed, build and programmed after a long term of study and hard work. I hope you enjoy it and enjoy the technology of mechatronics.
