Embedded Mechatronics System Design for Uncertain Environments: Linux®-based, Rasbpian®, ARDUINO® and MATLAB® xPC Target Approaches

Description

Industrial machines, automobiles, airplanes, robots, and machines are among the myriad possible hosts of embedded systems. The author researches robotic vehicles and remote operated vehicles (ROVs), especially Underwater Robotic Vehicles (URVs), used for a wide range of applications such as exploring oceans, monitoring environments, and supporting operations in extreme environments. Embedded Mechatronics System Design for Uncertain Environments has been prepared for those who seek to easily develop and design embedded systems for control purposes in robotic vehicles. It reflects the multidisciplinarily of embedded systems from initial concepts (mechanical and electrical) to the modelling and simulation (mathematical relationships), creating graphical-user interface (software) and their actual implementations (mechatronics system testing). The author proposes new solutions for the prototyping, simulation, testing, and design of real-time systems using standard PC hardware including Linux®, Raspbian®, ARDUINO®, and MATLAB® xPC Target.
