Abstract

In recent years, people paid more and more attention to industry and daily work, which is also being replaced and automated by robots. A robot is an automatically operated machine that replaces human efforts, although it may not look like a human or perform functions in a human way. Pick and place robot is one of the technologies used to perform picking and placing operations in manufacturing industry. The design of this system can eliminate human error and human intervention and make the work more accurate and efficient. Literature mentions that the pick and place robot is designed and implemented in various field, such as bottle filling industry, packaging industry and also rehabilitation for patients with arm disability or stroke. The purpose of this project is to design and develop a low-cost pick and place 4 DOF robotic arm. In this project, servomotors act as the joints of robotic arm and is controlled by programming of Arduino Uno. The Arduino Uno acts as the microcontroller in this project. There are four potentiometers attached to the Arduino Uno and each servomotor or joint of robotic arm is controlled by potentiometer. By moving the servomotors, the Arduino robotic arm able to rotate 180 degree for picking and placing some objects from one place to another. The servomotor used in this project is low torque and can also be used with high torque servomotor to pick up and place more heavy objects. In addition, the robotic arm also can be controlled via Bluetooth or smartphone applications.
