The PIR Based energy Conservation System For Corporate Intelligent Robot is a autonomous robot is an unmanned vehicle that runs in a field continuously by sensing human in the range of 12 meters in its path . The Human sensing is possible by an PIR sensor.An embedded project is a combination of hardware and software designed to perform a specific task. The main scope of this project Sensing humans and prevent the intruders.

                 Unlike current IR transmitter and receiver based projects in which the intruder has to pass through a certain region where IR radiation from transmitter is interrupted which in turn is detected as a intruder presence, this approach has following major drawbacks. Any non living body or animals which pass through this setup will trigger the alarm which is totally undesirable (we want only human intruder to detect). It is confined to very small region i.e. you can only attach this mechanism to passage or gate or door .You cannot detect presence of intruder jumping the fence with one sensor or big open spaces like your garden etc Advantage of Human heat based home security system. Totally eliminates false alarm triggering, i.e. it detects human intruder only. It can detect presence of intruder small to large area i.e. it can detect up to 14meters with 110 degree freedom. With the help of microcontroller and GSM the system can send SMS to the preloaded number when a intruder is detected.  Microcontroller will activate the alarm and lights once the intruder is detected. System is automatically disabled during the day time to avoid unnecessary alarm triggering, this feature can be enabled or disabled.

                 The moments of this robot is controlled using motors, the motor is driven with the help of driver i.e. L293D which consists of (H-bridge circuit) internally. The controller can’t drive a stepper motor which requires above 5 Volts, for that reason we required L293D driver externally.

AIM:RS232 TO RS485 CONVERTERS For Controll Applications project is designed to implementation MODBUS protocol using RS485 half duplex transmission.In the present days the field of electronics has took lot of developments and the security services in the presence and the absence of manpower. The industrial security system comes under the class of emerging embedded technologies.

DESCRIPTION: This project is designed to implement a MODBUS protocol using RS485 half duplex transmission. At the transmitter side data that is transmitted by the master is transmitted through LTC485 transceiver and at the receiver side the data is received through LTC485 and the resulted data will give to PC through RS232 communication. Max232 is a driver for rs232 communication. It is used in multiple master slave applications, RTU applications, HMI’s, innumerable gas and oil substation applications. Advantages are simplicity, standard Ethernet, availability of many devices.

The main scope of PC OPERATED ROBO USING WI-FI project is to control the Industrial Machines by using Wi-Fi Technology. An embedded project is a combination of hardware and software designed to perform a specific task. The main scope of this project is to develop the application for industrial automation using wire less communication as Wi-Fi embedded technology to reduce the complexity in design.

Wi-fi also known as 802.11b uses radio waves to send information at speeds of up to 11 Megabits per second over a range of up to 300 feet. When combined with a wireless access point or wireless router, it provides users with wireless high speed internet access. 

In our project we tried to demonstrate the wi-fi technology using small application. The project work includes study and design of hardware unit and software. We programmed Wi-Fi module which is interfaced to the micro-controller unit and some analog circuit which in turn drives the loads. So the complete project can be divided in to two modules i.e. Design of the user interface application and the other is the microcontroller Unit and its software which will be written in Embedded C Language.

PC controlled Robot using ZigBee network projects main idea is to develop a robot application which can control through remotely using a ZigBee network. This network is one of the widely used open source wireless network available in the market. This can be used for developing projects.

To control the direction of the robot we are using Xbee modules one as transmitter and the other as receiver. The transmitter is fixed to PC and the receiver is fixed to the robot on the other end. We send signals from PC through the Xbee (transmitter) to the receiver which is in built to the robot.

We can use this process to visually control the robot direction even though we are far away by connecting a camera in front of the robot.

Aim:The main aim of PC BASED SYNCHRONIZING AND SPEED CONTROLLING OF DC MOTOR project is to control the speed of DC motor and on/off the motor using PC.

Description:  If the voltage is varied, the motor would not be able to deliver the rated torque when operated at voltages lower than its recommended operating voltage. This problem can be over come by using PWM technique. PWM stands for pulse width modulation. The speed of the DC motor controlled by PC. This data is transferred to Micro controller serially. Here in Microcontroller  produce a square wave with variable duty cycle. The variable duty cycle in effect dictates the speed of the motor. Here the fundamental frequency of the square wave is constant for only the ON and OFF, time is appropriately manipulated. More ON time will cause the motor to run at higher speeds. As the ON time is reduced and proportionally the time is increased, the motor would slow down.

Typical 50% duty cycle: Equal On time and off time.
