Kinematics of Robotic Arms: Master the Math Needed to Calculate Exactly Where a Robot Hand Will End

Master the mathematics that allows industrial robots to position their hands with millimeter-level precision.

Every robotic arm-from a small desktop manipulator to a six-axis industrial robot-must answer one fundamental question:

Where will the robot's end-effector be after every joint moves?

The answer lies in robot kinematics.

The Kinematics of Robotic Arms is a practical, beginner-friendly guide that teaches the mathematics engineers use to calculate position, orientation, and motion in three-dimensional space. Rather than overwhelming readers with abstract equations, the book develops each concept step by step using clear explanations, visual examples, worked calculations, and practical robotics applications.

You will learn how to:

• Understand coordinate systems used by industrial robots
• Work confidently with vectors, matrices, rotations, and homogeneous transformation matrices
• Build coordinate frames using the Denavit-Hartenberg (DH) convention
• Model revolute and prismatic joints mathematically
• Calculate forward kinematics for serial robotic manipulators
• Determine the exact position and orientation of robot end-effectors
• Solve inverse kinematics for common robot configurations
• Recognize multiple inverse-kinematic solutions and singularities
• Understand robot workspaces and reachability analysis
• Compute Jacobian matrices for velocity relationships
• Analyze differential kinematics and end-effector motion
• Understand velocity propagation and manipulator dexterity
• Identify kinematic singularities and methods for avoiding them
• Explore redundant manipulators and null-space motion
• Apply kinematic models to pick-and-place robots, collaborative robots, SCARA robots, and six-axis industrial manipulators
• Implement robotic kinematic calculations using practical numerical examples
• Prepare the mathematical foundation needed for robot dynamics, motion planning, and control systems

Each chapter builds naturally upon the previous one, allowing readers to progress from basic geometry through complete robotic-arm models used in modern manufacturing, automation, logistics, healthcare, and research laboratories.

Whether you are a robotics student, engineer, researcher, maker, or software developer, this book provides the mathematical foundation required to understand how robotic manipulators calculate movement with remarkable accuracy.

You do not need an advanced mathematics background. Every concept is introduced gradually with diagrams, practical examples, engineering intuition, and worked solutions that make difficult topics easier to understand.
