RFID Based Pick and Place Robot

Since many years people try to replace human work with machines. Machines called robots are faster and more effective than people. The term robotics is practically defined as the study, design and use of robot systems for manufacturing. Robots are generally used to perform unsafe, hazardous, highly repetitive, and unpleasant tasks. They have many different functions such as material handling, assembly, arc welding, resistance welding and machine tool load and unload functions, painting, spraying, etc. Many elements of robots are built with inspiration from the nature. Construction of the manipulator as the arm of the robot is based on human arm. The robot has the ability to manipulate objects such as pick and place operations. It is also able to function by itself. The development of electronic industry robot system technology has been expanded increasingly. As one such application, the service robot with machine vision capability has been developed recently.

Step 1: Components Required

1) RFID Tag

2) RFID Reader

3)Arduino UNO

4) Jumper Wire

5)Servo Motor

6) DC Motor

7) Robotic Arm (https://www.amazon.in/Roinco-Metallic-Mechanical-robotic-Gripper/dp/B07FP28Q5J/ref=sr_1_8?keywords=robotic+ARM&qid=1576065471&sr=8-8)
