Foundations of Robot Kinematics: Modeling Robotic Motion

Ever wondered how robotic arms calculate precise movements to pick up objects or navigate spaces? Understanding the mathematical foundations of robot kinematics is the crucial first step for anyone aspiring to build or program intelligent machines. In this text-based course, you will transition from a curious beginner to a practitioner capable of modeling robotic motion. You will learn how to represent positions and orientations in 3D space, calculate forward and inverse kinematics, and understand the core mathematics that power modern physical robots. What you'll learn: - Understand foundational spatial representations, including rotation matrices and homogeneous transformations. - Calculate forward kinematics to determine the precise position of a robot's end-effector. - Solve inverse kinematics problems to find the joint angles required for specific targets. - Formulate velocity kinematics using the Jacobian matrix for smooth motion control. - Configure robot models using modern Unified Robot Description Format (URDF) structures. - Apply kinematic equations using Python-based symbolic mathematics and modeling libraries. The course begins with core geometric and algebraic foundations before guiding you step-by-step through open-chain kinematics and practical, computer-readable robot descriptions. This course is designed for aspiring robotics engineers, software developers, and students new to the field, requiring only basic algebra and a desire to learn.
