{ "item_title" : "Building Robot Simulators", "item_author" : [" Eleanor Sloane "], "item_description" : "Modern robotics development depends on simulation.Before a robot enters a factory, warehouse, laboratory, or public environment, engineers need a safe way to test movement, sensors, controllers, and software behaviour. A reliable simulator allows developers to experiment, debug, and improve robotic systems without risking expensive hardware.Building Robot Simulators is a practical engineering guide to creating a complete robot simulation engine from the ground up.Instead of only using existing simulation platforms, this book teaches you how robot simulators actually work internally. You will learn how physics, rendering, collision detection, sensors, actuators, robot descriptions, and control interfaces combine to create a functional virtual robotics environment.The book develops a complete simulator architecture step by step, allowing you to understand the principles behind professional robotics simulation tools.The simulator created throughout this book includes: Rigid-body physicsGravity, forces, torque, friction, and collisionsFixed, revolute, and prismatic jointsDifferential-drive robot motion3D rendering pipelinesRobot and world loadingVirtual sensorsActuator modelsController interfacesAutomated testingPerformance measurementOptional ROS 2 communicationBasic Python knowledge is recommended. Previous graphics or physics experience is not required because mathematical concepts such as vectors, matrices, quaternions, forces, and shaders are introduced when needed.Why Build a Simulator Yourself?Existing simulators are powerful, but creating a smaller simulator reveals the engineering decisions hidden behind professional tools.You will discover: Why unstable timing changes physical behaviourHow coordinate mistakes break robot modelsWhy collision geometry differs from visual geometryHow physics solvers create approximationsHow sensor models affect robot performanceHow repeatable tests reveal software problemsBy the end of this book, you will understand not only how to use robot simulation software, but how simulation engines are designed, structured, tested, and improved.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/9/79/819/102/9798191024424_b.jpg", "price_data" : { "retail_price" : "18.99", "online_price" : "18.99", "our_price" : "18.99", "club_price" : "18.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
