IOT Based Four DOF Robotic Arm With Record And Play Functionality

Project Area of Specialization RoboticsProject Summary

The Final year project named as “IOT Based 4 Degree of Freedom (DOF) Robotic arm with record and play functionality.” proposed in the department of computer science/software Engineering is described as the inexpensive and very effective multipurpose robotic or mechanical arm that is produced for multiple industries where either products or objects are picked from one place and dropped to another place. I-e Loading and unloading processes and thus, hiring different numbers of laboratories in this regard, which inevitably affect the business or industry's overall revenue. This was the dilemma of our project and the solution was so simple to incorporate a system that is one time expensive but can run efficiently for a long time. The Robotic or Mechanical arm which has been created by using 4 servo motors that makes Robotics arm up to 4 Degree of freedom (DOF). It has been constrained by an ARDUINO platform chip named as NOD MCU ESP8266 that is the Brain of the entire System which play out its activity by the given attribute signal in the form of Pulse Width Modulation (PWM) to Servo motors, which has been given by the client by using Web Page. This Internet of things (IOT) feature makes this project on of its kind because through this one can control this robotic arm wirelessly from anywhere. A web convention (IP) camera has been utilized to care for the mechanical arm working from better places. A buck converter is likewise used to give adequate measure of voltages to the mechanical arm which is adequate for it to play out the entirety of its activities. The aim of generating this Method Statement is to describe the step-by-step procedure for the implementation of a cheap but efficient autonomous Robotic Arm; in addition, to ensure that the execution of the device installation work meets the requirements of the project and serves the intended role to a satisfactory level. 8 | P a g e This form of robotic arm is not only used in industrial sectors, but can also be used by people with disabilities who are unable to transport their goods or objects. This robot will also help them pick and place their stuff from one location to another. The mechanical arm have various level of opportunity dependent on the reason for which it has been create, in this automated arm four servo engines are utilized to permit it to move in four distinctive point. It is accessible if various costs and sizes dependent on the working reason for it. The NOD MCU or ARDUINO has been customized which permit the servo engines to perform distinctive turn dependent on the information which has been given.

Project Objectives

This robotic arm will have up to 6 degree of rotation based on the purpose for which it is developed. This arm will change the life of those people who lose some part of their body in accident. It will provide then a new life with full functional body, with the help of which they can do all those thing which can imagine in their dream only. In future there have some chances that engineer will develop such a kind of robotic arm which will be control by the human brain and the engineer art still working on it to develop such kind of robotic arm. The purpose of our FYP (Final Year Project) is to provide relative to handicap people to do their daily work by their own self. Now the time a moving forward and new technologies and machines are coming in existence which help the people to do their work in a better way in short amount of time and effort in the same way this robotic arm will also change the people life in different prospective of life to perform different task.

Project Implementation Method

The working order of this robotic arm can be understand by just looking to the flow chart of this robotic arm in which all the thing and steps are clearly defined. The first phase of this robotic arm is start step from which the overall working will be start and the robotic arm will start work. In second phase when the electricity is provided to the robotic arm it will automatically come to its starting point which is well defined in its coding and each and every ting when its turn on it will automatically come to its starting point. In third phase the robotic arm will be connected through WiFi by which it well be controlled . In fourth phase an internet protocol (IP) address will be generated by the NODE MCU microcontroller by using which the robotic arm will be connected to others devices every time when the robotic arm will be connected to the new Wi-Fi network the internet protocol (IP) address will be changed and it will be shown on the display of the robotic arm. With the help of internet protocol (IP) address the user will be connected to the web page through which the user will control the robotic arm. A reset button I used in web page through which the previous setting will be removed and it will start working form its initial point. Sliders are used in web page though which each robotic arm motors will be controlled for each motors separate sliders are program. Record and play function is also used in this robotic arm by using which you can record the movement of the robotic arm and then you can play it multiple time as per the requirement.

In this block diagram you can see thing how the entire circuit Is developed and how the component is connected to each other. In NOD NCU micro controller the D1 and D2 is used for the display of the liquid crystal display (LCD) and voltage input (VIN) and ground (G) for the input of electric supply of the display. D4 is used for jaw servo 1, D3 for wrist servo 2. D5 for elbow servo 3, D6 for base servo 4 and voltage input (VIN) and ground (G) for the power supply to the servo motors through which it will move. In the way of the input supply of the NOD MCU micro controller and buck converter is used so that the specific amount of electricity can be transfer to the entire hardware the reason of using a buck convertor is to make sure that only the amount of supply which is need can be pass though the buck cover so that no damage can be done to the hardware of the robotic arm.
