Cell phone operated Robot is a Robot whose movement can be controlled by pressing the number of cell phone. The robot can move forward, backward, right or left which depends on the numbers you are pressing. The property of Robot to operate by the cell phone helps you to operate the robot from some distance.The Cell Phone controlled Robot uses DTMF (Dual tone-multi frequency) module. It is capable of receiving a set of command (instructions) in the form of DTMF (Dual tone multiple frequency) tones and performs the necessary actions.
Mobile-controlled robot
Mobile controlling is done mainly with DTMF decoder. DTMF stands for Dual Tone Multi Frequency. This module can take up-to 4 bits of data at a time (i.e. 0-15 decimal values).DTMF needs two mobile platforms, one for sending instructions while another for receiving them. This module contains a IC which decodes the signals received and convert it into 4 bit data.
Cell Phone Based Multiple Device Controller
Many times when we go out of home in a hurry and forget to’ on” or “off” certain appliances which sometimes creates a problem for us. Like in the morning we have to go to the office and in a rush, we sometimes forget to “off” the motor or water pump which lead to wastage of water and electricity or sometimes it happens we forget to “on” the motor which leads to scarcity of water.You can also control other electrical appliances like your TV, refrigerator, etc. Hence, to solve this problem you can use this simple circuit which will “on” and “off” your electrical appliances just by using phone.
Remote Control for Devices using Cell Phone
Many of us face problem when we out of our home like if we want to on the motor, so that when we reach home water will be filled in over head tank or we want to on other appliances like light fan etc. Hence to solve this problem we have describe a simple circuit which will on your device or appliances remotely and it will become off automatically after preset time interval. Many circuits have been developed so far to solve this problem but main advantage of this circuit is uses readily available components and this circuit is not expensive as well because this circuit is made using without microcontroller.
Cell phone operated Robotic Arm
This is also picked and place type robotic application. But this has a unique feature that it is controlled from cell phone. It’s all the movements are controlled from any cell phone. That means you can control this robot from anywhere in the world where GSM / CDMA network service is available. Isn’t it very interesting??!!!!????…..The robot has built in GSM / CDMA cell phone that receives signals from other cell phone. One has to call the number of the cell phone (that is inside robot) from his cell phone to activate it. Then by pressing different keys from 0 – 9 form the phone he can control the movements of the robot. It is 4-axis robotic arm. It’s all four motions are controlled by 2 DC gear motors and 2 servo motors.Let us start with mechanical structure of robot.
Cell Phone Operated Land Rover
You may have seen so many land rover projects on different websites or even on multyremotes.com as moon-walker and robo-vehicle. Most probably they are remote controlled (either IR or RF) or they may be automatic guided vehicles (AGV). This is also remote controlled land rover but as a remote control one can use his cell…
Cell Phone Controlled Robot without a Microcontroller
You may have come across many schematics and projects about a cell phone controlled land rover in many websites. But this is not the same.This article will show you how to make a cell phone controlled land rover without using a micro-controller. You read it right we are not going to use any kind of costly micro-controller for making the rover. Well you must have already come across the usual advantages of cell phone controlled Robot like, interference free communication, long range, etc. The motor driver L293d can control 2 motors bi-bidirectionally and has 4 inputs. The 4 outputs from the decoder IC is fed into the 4 inputs of the motor driver directly without using complicated circuits. Let’s see what’s more beneficial in this robot: Reduced circuit complexity, no need of any Programming, cost is highly reduced. Not everyone can afford a microcontroller along with its programmer and debugger boards.
Cell Phone based Device Control with Voice Acknowledgement
CHAPTER 1 INTRODUCTION The utilization of electrical power progressively increases in now-a-days. The demand for the electrical power is also increases over the entire world, particularly in India the demand for electrical power increases more and more because of the increase in population. The people utilize the power higher than their requirements because of their sophisticated…
Invention Story of Cell Phones
Mobile Phones have proved themselves to be one of the greatest gifts to the mankind. They have become an indispensible part of our lives. But going back in time, owning a mobile phone was confined to members of affluent class. All thanks to cost cutting techniques and innovations over a period of time; mobile phones are now affordable for everyone. Origin of this gadget is quite interesting. Starting from bulky mobiles phones which were as long and heavy as one’s forearms, to ultra thin and techno savvy handsets, mobiles phones have covered a long way so far. It all started with the basic telephony. Alexander Graham Bell was the first one to patent telephone in the year 1876. This technology was developed using the equipment designed for telegraph.
