This document describes an Internet of Things (IoT) based robotic arm project. The robotic arm is controlled remotely through a web interface using a WiFi module. The arm consists of servomotors connected by joints to mimic a human arm. A microcontroller receives commands from the WiFi module and controls the servomotors. The arm can pick and place objects automatically and its movements can be recorded to perform tasks repeatedly. The project aims to control machines from distant locations using IoT for applications in industries and medical fields.

There are several types of robot arms. We are going to use 4
Degree of Freedom it can be less or more as per the
requirements.
7. WI-FI MODULE
In order to communicate with the Robotic arm over the
internet, we are using Wi-Fi module ESP 8266. It is a self-
contained SOC and can be used with any microcontroller to
access Wi-Fi network. It consists of 32 bit low powered CPU,
and follows 802.11 b/g/n Wi-Fi standard. It has a powerful
on board processing and storage capabilities, and is
extremely cost effective.

The ESP module can be directly connected to our KL25Z
board. Here we are using serial communicationbetweenESP
8266 and KL25Z. A Wi-Fi based web server is made with a
graphical user interface, and controls are given through this
GUI. The signals when sent to the module can be given
serially to the controller board and then to the servo motors
of the robotic arm.

Internet of things has taken over all the heavy loads from human to itself. Internet of Things (IOT) is basically a connection of many devices to interconnect themselves. As Robots are used to help mankind in various environments if we combine the Robots and Internet of things we can achieve more than we can think of. This project discusses technological implications, open issues, and target applications in the IoT-aided robotics domain. 1. INTRODUCTION For the people who are indulged in electronicseitheras a hobby or as a profession who kind off happens to have more interest in robotics this project is the key in which most of precise work which humans cannot do repeatedly, this is where a robotic arm or we can say a pick n placerobot comes into picture. Robotics is the branch of mechanical engineering, electrical engineering and computer science that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing. A Robotic arm is a type of mechanical arm,usuallyprogrammable, with similar functions to a human arm; the arm may be the sum total of the mechanism or may be part of a more complex robot. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement. The internet of things (IoT) is the network of physical devices, vehicles, buildings and other items embedded with electronics, software, sensors, actuators, and network connectivity that enabletheseobjectstocollect and exchange data. The IoT allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency,accuracyandeconomicbenefit.When IoT is augmented with sensors andactuators,thetechnology becomes an instance of the more general class of cyber- physical systems, whichalsoencompassestechnologiessuch as smart grids, smart homes, intelligent transportation and smart cities. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure. 2. BLOCK DIAGRAM Fig -1: Block diagram and work flow of the project. 3. DESCRIPTION The main part of the project is the robotic arm, which can pick and place things from one place to another. To control this action we can move the robotic arm bygiving specific commands. The robotic arm is equipped with servo motors. These motors help to move the arm in desired direction. The motors are controlled with the helpofa micro controller(FRDM KL25Z). Theuserinterface whichisusedto control the robotic arm is made on a web pageoranapp.The control is given via the internet to the wifi module(ESP8266). This acts as the receiver and gives the received signal to the microcontroller.. The signal which is given to the robotic arm is actually sent through the internet

However the web page or the app must require a login ID and a password for security reasons, for a particular person to control the robotic arm. The movements which are made by the robotic arm can be recorded and saved. In this way the arm can do the same movements repeatedly whenever needed. 4. IOT(Internet Of Things) The Internet of things (IoT) is the internetworking of physical devices. The concept was simple but powerful. If all objects in daily life were equipped with identifiers and wireless connectivity, these objects couldbe communicating with each other and be managed by computers. The Three Cs of IoT: Communication -It is the interconnection between the user and system/device. Control and Automation - It is programmed once as if any changes in output parameter it will alert the uses and hence it can be control or it can be automated for any particular work. Cost Savings - Many companieswill adoptIoTtosavemoney. As when a machine loses to fulfill a companyproductontime the company will lose its money. With new sensor information, IoT can help a company to save money by reducing equipment failure and allowing the business to perform perfectly. 5. FRDM KL25Z BOARD Fig -2: KL25Z board with pin description. (Source: developer.mbed.org) The Freedom KL25Z is an ultra-low-cost development platform for Kinetics L Series microcontroller built on ARM Cortex-M0+ processor. Features include easy access to microcontroller input/output, battery-ready, low power consumption, a built-in debug interface for flash programming and run-control. The FRDM-KL25Z is supported by a range of NXP. It also has third-party development software.Towritea programit has an online developer site in which you can develop codes to burn it on this development board you can now use mbed.org at no charge, with full access to the online SDK, tools, reusable code which means no downloads. 6. ROBOTIC ARM It is a combination of not only a particularfieldbuta fusion of many fields such as mechanical, electrical, electronic engineering, computer science, technology, math and science. Robots are indispensable in many manufacturing industries. More than this, if it is programmed for a task then a robot perform that task repeatedly with a high accuracy that surpasses that of the most experienced human operator. To move like a human arm we need actuator to perform it like a human arm. Actuators are devices which converts the electrical energy into physical motion. Fig -3: Structure of Robotic arm. In this robotic arm we are going to use servomotorsas servo motors gives good accuracy than any other motors.To look like a human arm we are going to connect this using servo clamps. The servo clamps are of different types, bythe help of this various clamps a robotic arm is built. To pick and object and to put it from one place to another we are going to use a gripper. This gripper is also known as an end effector.
