This book on "An Introduction to Robotics" deals with the basic principles of the subject. All topics have been introduced in a simple manner. The book has been prepared to suit the requirements of students preparing for degree and diploma examinations in engineering. This book gives insight into the brief history and conceptual development of robotics, its components, and robot classification. It explains robot kinematics, its controlling system, differential motion, robot dynamics, homogeneous transformation, arm singularity effects, etc. in a comprehensive manner. This book focuses on the use of various robotic sensors and robotic cameras for a variety of automated applications that are required by IR 4.0. The use of embedded systems and robotic vision has been suitably introduced in the book. Actuators are critical components of a robot, which are briefly explained alongwith the robot's programming and transformation
