Abstract

A Robotic Arm is a programmable mechanical device designed to mimic the movement and functionality of a human arm. It consists of interconnected segments joined by joints, enabling precise and versatile motion, often controlled by algorithms and software. Equipped with an end effector, such as a gripper or tool, it can perform a variety of tasks across different fields. Robotic arms operate with degrees of freedom (DoF), which determine their range of motion and complexity. They move through rotational or translational joints powered by actuators and are guided by sensors and microcontrollers for precision and adaptability. This review paper explores the advancements in robotic arms' design, with a focus on lightweight structures and modular components that enhance overall performance, flexibility, and efficiency. A thorough analysis of the fundamentals of kinematics, such as forward and inverse kinematics, reveals how important they are for facilitating accurate movement control. The application of sophisticated control systems that maximize the performance, dependability, and versatility of robotic arms is also covered in the study. The range of uses for robotic arms has greatly increased due to these technical advancements, making them essential in a variety of industries, including manufacturing, healthcare, logistics, and many more
