A trajectory tracking robotic arm is an automated mechanical system designed to follow a predefined path with high accuracy, stability, and repeatability. The primary objective of this project is to develop a robotic arm capable of executing smooth and precise motion trajectories for applications such as material handling, sorting, pick-and-place operations, and industrial automation. The system integrates microcontrollers, servo motors, sensors, and control algorithms to achieve reli- able movement control. In this project, trajectory tracking is implemented using real-time feedback and control techniques such as PID control, which minimizes the error between the desired and actual position of the arm. The robotic arm is programmed to follow specific motion profiles while maintaining speed, orientation, and accuracy under varying load conditions. Sensors like IR arrays, color sensors, and encoders enhance its ability to detect objects and adjust its path dynamically. The developed system demonstrates efficient trajectory tracking performance with improved precision and reduced response time. This work highlights the importance of closed-loop control, sensor fusion, and lightweight mechanical design in achieving accurate robotic motion. Such robotic arms have significant potential in industrial automation, agriculture, healthcare, and service robotics, contributing to improved productivity and re- duced human effort.
