GSM based SPY Robot

In the recent past, wireless controlled vehicles had been extensively used in a lot of areas like unmanned rescue missions, military usage for unmanned combat and many others. But the major disadvantage of these wireless unmanned robots is that they typically make use of RF circuits for maneuver and control. Essentially RF circuits suffer from a lot of drawbacks such as limited frequency range i.e. working range, and limited control. To overcome such problems associated with RF control, few papers have been written, describing methods which make use of the GSM network and the DTMF function of a cell phone to control the robotic vehicle. This paper although uses the same principle technology of the GSM network and the DTMF based mobile phone but it essentially shows the construction of a circuit using only 4 bits of wireless data communication to control the motion of the vehicle without the use of any microcontroller. This improvement results in considerable reduction of circuit complexity and of manpower for software development as the circuit built using this system does not require any form of programming. Moreover, practical results obtained showed an appreciable degree of accuracy of the system and friendliness without the use of any microcontroller.

ABSTRACT— Over the years, robotic vehicles used in unmanned rescue missions, security in jewelry stores, military combat, security in bank vaults and many others, make use of wireless technology in controlling the vehicles. The major drawback of these wireless unmanned robots is that they make use of radio frequency (RF) circuits for maneuver and control. Principally, RF circuits suffer from the disadvantageof limited control range. To overcome this challenge, other methods have been implemented which make use of the global system for mobile communication (GSM) network and the dual tone multiple frequency (DTMF) function of a cell phone to control the robotic vehicle. Although this work uses the same principle as the technology of the GSM network, it essentially shows the construction of a circuit using Graphical User Interface (GUI) and GSM modules which send commands to control the movement of the vehicle with the use of a microcontroller. The GUI generates different coded signals with the help of visual basic. These signals are transmitted through the communication (COM) port of the personal computer (PC) to the GSM module interface. These commands are sent wirelessly to another GSM module interfaced with the microcontroller and they control the robot accordingly. As the vehicle moves about the target area, once human presence is detected by the PIR sensor interfaced with the microcontroller, the onboard global positioning system(GPS) module interfaced with the microcontroller sends both the latitude and the longitude information of the detected human presence to the control station via the GSM module to initiate emergency response from the control station. The robotic vehicle was implemented, the PIR sensor detected human presence and sent an SMS containing the latitude and longitude of the location to the control station which was viewed from the Google Map on the GUI application. GUI Commands sent from the remote robot control station were received and the robot moved accordingly.

This paper describes a wireless robot which performs the necessary actions by receiving a set of instructions in the form a DTMF frequency. In this project we can control the robot directions like forward, backward, left and right by sending call from the mobile and also performs operations like metal detection and video camera surveillance. This project mainly consists of 2 sections, one is mobile unit and the other one is robot unit. The GSM modem which is fixed at the robot receives the dtmf frequency sent by the mobile and gives the instructions to the microcontroller to control the robot directions. In this project, we interface 8051 microcontroller with GSM Module. The protocol used for the communication between controller and GSM modem is UART (Universal Asynchronous Receiver-Transmitter). This system continuously checks for message to take the decision for controlling the robot.

Robotics is an interesting field where every engineer can showcase his creative and technical skills. As the development of individual and cooperating autonomous robots advances, the need for a robust and reliable communication method becomes apparent. This paper summarizes a the feasibility of implementing Dual-Tone, Multi-Frequency (DTMF) as an alternative mean of robotic communication to Radio Frequency (RF). The user in order to control the robot should make a video call to the 3G enabled phone attached in the Vehicle, from any another 3G enabled phone, which can send DTMF tones by pressing the numeric buttons and can view the video output. The cell phone in the Vehicle will be kept in auto answer mode. So, after a ring the cell phone accepts the call and starts video transmission. Now for the DTMF tones pressed, the tones are fed to the circuit and the corresponding actions such as move forward or backward, turn left or right, target identification and locking, missile launching and parameter monitoring using black box are performed. Index Terms-DTMF technology, 3G wireless communication, black box.

Today Robotics plays a fundamental role in fields of medicine, industries, home automated systems and many others. The methodology of DTMF (Dual Tone Multi-Frequency) with GSM module is used for designing our robot. Robot is controlled by a mobile, through this we can make our robot communicate on a large scale over a large distance even from different cities or place. This robot has a number of merits as well as important features such as password authentication, avoiding obstacles in its path with fire detection[POF] so that robot can protect itself from fire and hence immediately provide an alert through text messaging to the calling person with sensors being automatic in nature.

This project is designed to develop as a robotic vehicle that can be controlled by a cell phones. DTMF commands from a phone send to another cell phone which is mounted on the robotic vehicle. These commands are fed to a PIC microcontroller of 8-bit architecture to operate the vehicle movement through motor interface. Conventionally Wireless-controlled Robots Use Rf Circuits, Which Have Limited Working Range, Limited Frequency Range and Limited Control. Use of a Mobile Phone for Robotic Control Can Overcome These Limitations. It Provides the Advantage of Robust Control, Working Range as Large as the Area of the Service Provider, No Interference with Other Controllers. Although the Appearance and Capabilities of Robot Vary Vastly, All Robots Share Feature of a Mechanical, Movable Structure Under Some Form of Control. The Control of Robot Involves Three Distinct Phases: Perception, Processing and Action. Generally, the Preceptors Are Sensors Mounted on the Robot, Processing is Done by the On-board Microcontroller or Processor, and the Task is Performed Using Motors or with Some Other Actuators. In This Project the Robot is Connected to Gsm mobile (using DTMF technology) Which is Controlled by User Mobile Phone. With the Help of Commands We Can Move Our Robot in Desired Direction as Per Our Requirement. COMPONENT USED: * DTMF DECODER * 8-BIT PIC MICROCONTROLLER * CELL PHONES * DIODES * BATTERY(6-VOLT) * DC MOTOR * WHEELS ETC. Project By Abhi Sharma.

Generally wireless controlled robots are used RF circuits which have the drawbacks of limited frequency range, limited working range and limited control. To overcome these drawbacks we go for mobile phone controlled robots it provides robust control and working. RF circuits are used only limited coverage area only but mobile operated robot is used for wide range of area. In this method a mobile phone is call the another phone attached to the robot. Whenever the call is attend the number is pressed by a phone which is used as remote control the tone corresponding to the button is hear. This tone is called as DTMF (Dual-tone multiple frequency).

The aim of the proposed project is to use a mobile phone to drive a car. The project necessitates the use of two mobile phones, one to control the robot and the other to deliver DTMF signals to the robot vehicle. The commands are received by a DTMF decoder connected to an 8051 microcontroller, which then controls the vehicle movement with the help of a motor driver. Thus, with the motor driver IC, two DC motors enable vehicle movement based on commands supplied from the phone. The power source is a battery. New technologies can be implemented using a robotic vehicle. The Dual Tone Multi Frequency (DTMF) system is utilised to control the robot. In everyday life, DTMF technology can be valuable. To this generation, DTMF technology is unrivalled. The science of Digital Signal Processing underpins DTMF technology. Previously, a Radio Frequency circuit was employed for wireless control, but it had a significant disadvantage in terms of range. As a result, it restricts control and has a negative impact on the vehicle's performance. DTMF, on the other hand, transforms this deprivation of the Radio Frequency circuit into domination. It gives you a wider range of options for working and produces better results. The phone in the microcontroller is used to operate and maintain this system. The remote handling operation of a robot using Dual Tone Multi Frequency is referred to as wireless communication.

As wireless control is widely used nowadays because of their wide range of control. The wireless controlled robots use RF circuits, which were run-over by wireless control using mobile network, but both have the drawbacks of limited range & operation. The operation of control using mobile network is limited with the availability of cellular network. This drawback can be removed by replacing cellular signal with satellite signal. This enables the user to control the robot in remote areas too.

In modern technological innovation, robotics and artificial intelligence (AI) method are now applied to do our manual tasks. Robots are becoming common in our homes, public places, industries, entertainment, and relaxation centers hence, we need to control and monitor them for easy and suitable usage. In the research, we have not only proposed but developed a robot that can be controlled by mobile phones through which we can call for some emergency situations for the Fire brigade, Law enforcement agencies (Police, Army), National Emergency Management Agency (MENA), Area Guard so on. This mobile phone-controlled robot is powered by a 9V battery for the system circuit. Whenever the user calls the mobile phone, the call is received by autoanswer mode and as the call is ongoing, the user presses a button on his handset the tone that is generated is decoded by the DTMF decoder, and the comm and is passed to the pre-programmed microcontroller. The Microcontroller then processes the command signal which activates the motor driver ICs for motion. This system can also be useful in reconnaissance or surveillance and applicable anywhere the GSM network service is active. The designed system is compactable, robust, and cost affordable.
