Design and Development of a Weight Sensing Based Object Sorting Robotic Arm

The increasing importance of robotics in various industries has greatly simplified and improved human life. One area where robotics can be particularly beneficial is in the sorting of products within the manufacturing sector, based on criteria such as colour, weight, and size. To address the challenges associated with sorting, a combination of robotics and weight sensing technology can be employed. The objective of this project is to design and develop a robotic arm that incorporates a weight sensing system. A load cell is utilized to detect the weight of the object being picked up by the arm. The load cell sensor transmits weight signals to an Arduino Uno, which then generates control signals for a motor driver. The motor driver, in turn, regulates the movement of the motors situated between the links of the robotic arm. The arm consists of a base motor for rotation, a shoulder motor for bearing weight, an elbow motor, and a motorized gripper for securely holding the objects. This innovative model has practical applications in factories where it can be utilized for efficient job sorting.
