Design of Robotic Manipulator and Its Control Techniques

In recent years, a field of robotics has made incredible strides, with robotic arms playing a crucial part in various industrial and research applications. Robotic arms must be precisely controlled to be used for tasks like manufacturing, healthcare, and autonomous navigation. This research paper presents different methods for measuring angles and distances to improve the precision and control of robotic arms. The major aim of the work is to develop and study different control techniques for robot arm operation and obstacle detection. This work uses stepper motors with encoders for sensing angles and ultrasonic sensors for sensing distances. This research investigates the integration of ultrasonic sensors for distance measurement in addition to angle sensing. Ultrasonic sensors generate sound waves of higher frequency and measure the time taken by the sound wave to return after striking any object. This study demonstrates the effectiveness of the suggested angle sensing and distance measurement methods in improving the control and adaptability of robotic arms through experimental findings and performance assessments. The research provides the robotics community with useful information paving the way for better robotic arm designs and applications in various industries. Ultimately these innovations aid in the development of automation and the creation of stronger, more flexible robotic systems.
