Use of mobile phone for robotic control. The robot can be used for reconnaissance and detecting metal objects. The camera and micro-phone mounted on the robot will give the detailed information of where the robot is and who is around. The signal is then transmitted to the observer via audio/video transmitter-receiver.

Control Area Network controls the security of the Electronic equipments using the RS-485 protocol. We use CAN for Monitoring Sensors. Data can be stored in the System and the software is used for backup. We can get reports on hourly, weekly and monthly basis

Water spy is a specially designed Robot for under water operation. As its main aim is to work underwater so main objective should be that it should be capable of moving in any direction so we had provided it with such a driving power that it can move deep beneath water. To provide driving power six motors have been used. The robot is controlled by remote control. Wireless control of robot is achieved using DTMF code signals. Microcontroller AT 89C51 has been used to control the direction of robot. H-bridge motor driver circuit has been used to provide reversible drive to the dc motors. Main body of Robot is made up of PVC pipes.

The project consists of temperature & light monitoring and controlling. This unit is installed on a Robot which moves through the greenhouse on a predefined track. This project will consist of three basis modules. First is "Parameters Monitoring" second is "Parameters Controlling" and third is automatic movement of Robot on a predefined path.

In this project, the robot is controlled by a mobile phone that makes a call to the mobile phone attached to the robot. In the course of a call, if any button is pressed, a tone corresponding to the button pressed is heard at the other end of the call. This tone is called "Dual Tone Multiple-Frequency" (DTMF) tone. The robot perceives this DTMF tone with the help of the phone stacked on the robot. The received tone is processed by the microcontroller with the help of DTMF decoder. The microcontroller then transmits the signal to the motor driver ICs to operate the motors. The metal detector circuit mounted on the robot detects any metal object around it.

The pick and place robot is a microcontroller based mechatronic system that detects the object, picks that object from source location and places at desired location. For detection of object, infrared sensors are used which detect presence of object as the transmitter to receiver path for infrared sensor is interrupted by placed object. As soon as robot senses presence of object, it moves towards object, picks it with end effectors, and moves along way gantry and finally place it on destination. If another object causes interrupt, it again does the same job. Whole process is controlled by micro controller.

This project is used to measure the water level in a dam, after a particular time interval and to store them it into a memory IC for the sake of records. Later a person can access the memory using this project and see the previous records using a keypad and LCD. This data can be sent to a computer through serial port.

Main concept behind this project is to measure and display the number of persons entering in any room like seminar hall, conference room. LCD display placed outside the room displays this value. And when number of persons inside the room are zero, power supply inside the room can be cut using a relay interface. Second part of project serves the functionality of a door-latch opening using a password entered through keypad. As well as sending this data to a computer through serial port. This module also turn on buzzer if 3 wrong passowords are entered consequently. User can change this password anytime he/she wish using a keypad.

This project is used to measure the various parameters like Temperature and Light and display them on a LCD. Temperature and light is sensed by respective sensors and sensor output is ampilfied and given to ADC. Microcontroller controlls these parameters and keep them at some predefined levels using realy interface. These relays can be connected to Fan/Heater. At the same time these values of temperature and light to a computer through serial port.

Use of automated system for car parking monitoring will reduce the human efforts. Display unit is installed on entrance of parking lot which will show LEDs for all Parking slot and for all parking lanes. Empty slot will be indicated by glowing the respective LED.

When supply is turned user have to select Mode i.e. Voting mode or Counting mode. In Voting Mode, “Vote mode” is displayed followed by “Please vote”. After a vote being given, “Please wait...” is displayed and again enabled for voting after Control switch being pressed by the voting Authority. In Counting Mode, “Counting mode” in displayed on the screen, and total number of votes to respective candidate can be displayed on the screen by pressing the respective key assigned to them. Clear mode, Press clear switch when all entries are required to be erased. Clear switch should be pressed before voting procedure. Buzzer indication, Pressing of key in voting mode is indicated by a buzzer sound. Controller switch: This switch is provided for enabling the keypad in voting mode. Is under the control of voting authority.

This project can be used for Advertising or for providing information at various places like shops, government offices, hospitals, railway stations. The Rolling display is prepared using 5 X 7 Matrix LEDs which means LEDs are arranged in a pattern consisting of 5 columns and 7 rows. A matrix of 5 X 7 LEDs contribute to a single character. Here we have used 6 characters which means 6 matrices. The actual physical diamension of single matrix is 10 cm by 8 cm, so diamension of complete display is 10 cm by 48 cm. A keypad used to select which message has to be displayed. These messages are stored in a EEPROM. PC interfacing is used for sending data to computer.

This project which will consist of two basis modules. First is ?Data Monitoring? & other is ?Data Storage? A display unit will show the value of parameters. This will help for the person to know the values, for this purpose we are going to use various sensors, which will be connected to ADC. The other module is named as parameter storage. It can be used to store the parameter values in the memory. We are going to use EEPROM memory IC. These values can later seen using a keypad provided on the front panel. This system is useful as many times its difficult to measure the parameter values manually and also this module is more accurate than the domestic system.

Set the interval time and buzzer time through keypad. An internal clock will run inside the controller which will turn on the buzzer at the desired time periods. PC interface is provided so as to send the data to the computer.
