This document describes a project to design a 3-axis robot that is controlled by a cell phone and includes artificial intelligence capabilities. The robot can detect obstacles, fires, and metals and alert the user. It is powered by an ARM 7 processor and uses sensors for smoke, temperature, intruders, and metals. The robot's movements along three axes are controlled remotely by a cell phone for applications like security, roving, and antenna positioning. The design is modular for understanding and future modifications could expand its usefulness.
ARM7(LPC2148)PROJECTS-ROBOTICS- cell phone controlled three axis robot with artificial intelligence
- 1. ARM 7 PROCESSOR BASED - CELL PHONE CONTROLLED THREE AXIS ROBOT WITH ARTIFICIAL INTELLIGENCE Introduction A robot is an electro-mechanical device that can perform autonomous or preprogrammed tasks. A robot may act under the direct control of a human (eg. the robotic arm of the space shuttle) or autonomously under the control of a programmed computer. Robots may be used to perform tasks that are too dangerous or difficult for humans to implement directly (e.g. nuclear waste clean up) or may be used to automate repetitive tasks that can be performed with more precision by a robot than by the employment of a human (e.g. automobile production.) Abstract: This project aims at designing a robot, which has freedom of movement along all the 3 axes and its motion is controlled by means of wheels. The user can control the movements using a Cellphone from a remote place. The system is made more useful by introducing artificial intelligence to it. By artificial intelligence, we mean designing the robot is such a manner that in situation which require decision making, the robot identifies the presence of the obstacle, alerts the user and moreover awaits instruction from the user for the further action. Other condition, which the robot can determine, is presence of fire. I.e., high temperature and presence of metals in vicinity.
- 2. Existing Technique and Proposed Idea: Although robots exists which can be controlled by a short range wireless or wired communication only. Today GSM Communication have become a common thing with the advancement in the communication field. So we planned to implement the GSM Communication (using cell phone) for controlling the actions of a Robot. Working: A robot is constructed and is connected to a cell phone with associated electronic circuits. Now the user can dial the no of the cell phone to which the robot is connected from a remote place using another cell phone. The electronic circuits will identify the incoming call and connects the call for the user to communicate with the robot. Now the user can control the movements by pressing the desired key. For eg 1 – Forward movement, 2 – Reverse, 3 – left etc. This project is divided into modules for better understanding of the circuit.The modules include Mobile phone Control Circuitary PIC Microcontroller Board Optocoupler With Stepper Driver Board Stepper Power Supply Board. Fire Sensing Unit Smoke Detector High Temperature Sensing Mobile Phone Control Circuitary
- 3. This Board is used to convert the commands given by the cell phone to logic level signal and provides the input to the microcontroller. PIC Microcontroller Board This is the board which contains PIC Microcontroller Chip as well as the clock Circuitary, Reset Circuit and Power Supply for the MicroController. OptoCoupler With Stepper Driver Board. The need of Optocoupler is to isolate the Microcontroller Board form the Stepper Motor to restrict any high voltage to the Microcontroller board. And this board also contains stepper Driver circuit to amplify the Voltge and to withstand high current because the pulse coming out from the Microcontroller is not tough enough to drive the Motor. Stepper Power Supply. This board contains the power Supply for the stepper motor and relay driver. Flame Sensor An LDR is used as a flame Sensor. And the output is given to a Digital input of the Controller. So when the Flame is sensed we can give alarm +Visual Indication and immediately transfer the Message to a nearby Fire Station. Temperature Sensor A Thermistor is used a Temperature Sensor. When Over Temperature is detected We can stop the movement of the Model. Also we can give the Visual +Alarm Indication.
- 4. Intruder Sensor An Infrared sensor is used as a intruder detector. So when an intruder is sensed we can redirect the movement of the Model. Metal Sensor A Proximity Metal Detector used as a Bomb detector. So when an bomb is detecte we can indicate it through the computer. Smoke Detector: A smoke detector is used to detect Smoke in an area and provides alarm output. All this information is transferred to a remote computer and further to a remote mobile phone.

- 6. Reasons For selecting the field: As of today Robotics is the vast field to explore the things without human intervention. The word robot is used to refer to a wide range of machines, the common feature of which is that they are all capable of movement and can be used to perform physical tasks. Robots take on many different forms, ranging from humanoid, which mimic the human form and way of moving, to industrial, whose appearance is dictated by the function they are to perform. Robots can be grouped generally as mobile robots (eg. autonomous vehicles), manipulator robots (eg. industrial robots) and self reconfigurable robots, which can conform themselves to the task at hand. Advantages of our Project Utilizes High speed embedded controller Cellphone controlled Freedom movement for all three axes. Flexible automation type. Rigid mechanical construction.
