"Design and Fabrication of Pick and Place Robotic Arm with 4DOF" Dhiraj Mahendra Pandey, Ganesh Dilip Jambhale, Omkar Dhananjay Saraf, Samadhan Jayvant Shinde, Prof. Dhananjay M. Bhoge. Mechanical Engineering Department, Marathwada Mitra Mandal's Institute of Technology, Lohgaon, Pune, India ---------------------------------------------------------------------***--------------------------------------------------------------------Bluetooth module is being used. Android application is being Abstract - The more increase in the number of industries in developing countries, the more workers are required. To reduce the cost of the labor force and to increase the manufacturing capacity of industries, advanced robot arms are more needed. This paper aims to eliminate the control of the robotic arm for picking and placing the required object. The arm is constructed with four links and four servo motors to drive the robot arm. Arduino Nano is been used to generate the required control signals for servo motors. The robot is to be developed for assisting/replacing workers in a factory involving material handling of small components such as electronic items, nuts and bolts, small mechanical components, etc.
developed for the prototype and it is been designed in “MIT app inventor” which is open online platform to design android app having block coding system (drag and drop).

To design and develop a system of robotic arm that can perform various operations in industry such as to pick the object from one position and place it over desired position, handle the material effectively, which can be controlled automatically and manually. Following are the main objectives of this project:
1.INTRODUCTION The pick and place robotic arms handle repetitive tasks while making it available to human workers to focus on more complicated work. Robotic arms are usually mounted on a stable stand, pick and place robotic arms are positioned to reach different areas to perform work. For, example in order to fulfillment applications in which items are placed onto a conveyor, picking bin or directly into a packaging container, the robot should come with four to five axes. This project is been designed the robotic arm with four degree of freedom which will assist/replace workers in the industry. The main objective of the project is to design and fabricate the robotic arm which may perform various operations in industry such as pick and place the object, material handling, which can be controlled automatically and manually. The robotic arm may be classified into four parts:
4. MATERIAL SELECTION The material properties were taken into consideration during the material selection process: strength, lightness, availability and Ease of cutting. The material should possess sufficient strength so it will ensure that each link of the arm is able to bear the load imposed on it by motors, other attached links and the payload. Lightness of the material reduces the torque requirement of the robotic controllers, thus minimizing the cost. The material needs to be readily available and easy to cut because the fabrication of some parts of a robotic arm involves the cutting of intricate shapes which will go for laser cutting. The main objective is to have mild steel as selection for arm and servo brackets because it may sustain the force exerted by servo and also it is easy to do laser cutting operation as its thickness is less. The main objective is to select aluminum for gripper because it is lightweight and can handle the weight concentration properly.
• Base • Servo shoulder • Arm • Gripper The pick and place robotic arm has a base which is stationary and has joints with servo shoulder. There are four servo motors for the smooth operation of robotic arm. Ankle and servo shoulder is the main part to assist gripper for the working of robotic arm. The main functioning of the robotic arm is handled by the sensor technology which is been used for the smooth operation to pick the object from one position and place it over desired position. This project is such designed it is highly secure and cost effective as HC05
