This edition covers different topics from mechatronics and robotics, including mechatronics basics, robotics arms and manipulators, sensors and actuators in mechatronics. Section 1 focuses on mechatronics basics, describing a brief history of industrial robotics in the 20th century; an IoT model for cyber-physical manufacturing systems; 3+1 SysML view-model in model integrated mechatronics; design and development of mechatronic application in agricultural irrigation device. Section 2 focuses on robotics arms and manipulators, describing design and development of a competitive low-cost robot arm with four degrees of freedom; an adaptive robust approach to modeling and control of flexible arm robots; interactive heuristic d* path planning solution based on PSO for two-link robotic arm in dynamic environment; optimal task placement of a serial robot manipulator for manipulability and mechanical power optimization; kinematical analysis and simulation of high-speed plate carrying manipulator based on Matlab. Section 3 focuses on sensors in mechatronics, describing flexible impact force sensor; a sensing and robot navigation of hybrid sensor network; a study on vehicle detection and tracking using wireless sensor networks; deployment of pre-industrial autonomous microbe sensor in Saudi Arabia's injection seawater system. Section 4 focuses on actuators, describing a survey of modeling and control of piezoelectric actuators; experimental investigation of photostrictive materials for MEMS application; theory and simulation analysis of the mode shape and normal shape actuators and sensors; experimental study of the response of transonic diffuser flow to a piezoceramic actuator at diffuser throat; an ARX-based PID-sliding mode control on velocity tracking control of a stick-slip Pi-ezoelectric-driven actuator.
