Abstract

This is my abstract. This project aims to design and build an IoT Robotic Arm for pick and place applications with a conveyor. This project is expected to pick an object on a conveyor automatically and sort the object by its color. The hardware used is a unit of Arduino Mega 2560, an HC-05 Bluetooth module, three SG90 servo motors, three MG996r servo motors an L298N motor driver module, a TCS3200 color sensor, E18-D80NK infrared sensor, a DC motor, and battery. The operation starts by running the DC motor, an object will be moved by the conveyor belt. If the infrared sensor senses the object, the conveyor (DC motor) will stop, then the Arduino Mega will move the robotic arm’s end effector (Servo motors) to the object, and the gripper will grip the object and move it to the color sensor for color. The robotic arm will subsequently place the object in the sorting boxes based on its color. And using the HC-05 Bluetooth module, data from a smartphone to an Arduino to carry out any desired function. For instance, a user can use a smartphone function to control each and every movement made by the servo motors, or a robotic arm can present an automation pick-and-place application utilizing merely a mobile device instead of a controller. In this project, an app inventor has been utilized to operate the robotic arm. With the help of Bluetooth connectivity, this program may enable the user to modify all the buttons and features. The project’s outcome demonstrates that the app can successfully control each of the six servo motors. Apart from that, this project can also function despite being attached to a conveyor. The gripper will grab the object and move to the position of the color sensor to determine the color when an object has been detected by the infrared sensor, which causes the DC motor to halt. However, some issues sometimes arise, such as when the DC motor becomes stuck and needs to be rotated slightly in order to continue operating. The project’s contribution is the automation of an IoT robotic arm, which can simultaneously boost productivity and precision while lowering the cost in manufacturing to replace human
