Design and Implementation of Integrated Mobile Operated Remote Vehicle

Abstract : This paper presents the technical construction of the vehicle controlled by user mobile. The designed GSM based vehicle could be operated from almost anywhere if GSM network exists. The procedure commences with initiating a call from the cell phone which is auto received by GSM module stacked in the vehicle. In the course of a call, if any of the keypad buttons was pressed a tone corresponding to the button pressed is heard at the other end of the transmission which is called Dual Tone Multiple Frequency (DTMF) tone. The received tone in the cell phone at the vehicle is processed by the ARM7 LPC2148 controller. These processed signals are given as input to the motor driver IC (L293D) which drives the vehicle in 3600 and also to perform the actions needed by laser weapon system.

 EXISTING SYSTEM :

 ? We are willing to make a cell phone based remote control vehicle where it can be operated almost anywhere if GSM network exists. ? It can be stated/covered that replacing the existing handset with a 3G one will not only extends operation of the developed circuit but will also enable some more additional features to be employed alongside the present one. ? If an additional alarm circuit along with sensors is implemented along with existing one, the system will then be able to notify the user when an alarm initiates via calling a fixed number. ? Such basic improvements can be made on the existing system as and when the requirement arises without making any major changes in the principle design of the USV.

 DISADVANTAGE :

 ? In this paper, phones using GSM network interfaced with a microcontroller is used to remotely control an unmanned robotic vehicle thus overcoming distance barrier problem and communication over obstacles with very minimal or no interference but is solely network dependent. ? Moreover shooting infrared outdoors on a bright sunny day is often problematic, since sunlight can interfere with the infrared signal. ? Use of a GSM network (in the form of a mobile phone, a cordless phone) for robotic control can overcome these limitations. ? IR systems suffer from these problems so to overcome this; a signaling scheme utilizing voice frequency tones is employed.

 PROPOSED SYSTEM :

 • Many animals are on the verge of becoming extinct, including the tiger to name a few. The spy robotic car can really be of help to us in this purpose. • The remaining controls are available to serve purposes dependant on the area of application of the RCV. We have tried to reduce the circuit complexity and improve upon the human machine interface. • The design procedure of an unmanned surface vehicle as presented in this paper can be further extended to include IR sensors and also a system to include password protection for the USV. • We have tried to reduce the circuit complexity and improve upon the human machine interface.

 ADVANTAGE :

 ? It provides the advantages of robust control, working range as large as the coverage area of the service provider in comparison with that of an IR system, no interference with other controllers. ? Super-regenerative modules are generally imprecise as their frequency of operation varies considerably with temperature and power supply voltage. ? Super heterodyne receivers have a performance advantage over super regenerative; they offer increased accuracy and stability over a large voltage and temperature range. ? This stability comes from a fixed crystal design which in turn leads to a comparatively more expensive product. ? The laser weapon system installed will make the project more efficient.
