Electronic Eye Embedded System Project

With the increase of robberies, people are acting smarter to cheat the concerned security. To avoid this, we need security system and this can be fulfilled by this project “Electronic Eye”.

This project is based on Intel’s 8051 families of the microcontroller. This Embedded system project is based on highly sensitive PIR Sensor. When you are away for your house and if anyone tries to enter the house by any means the device generates an alarm signal, that is enough to chase the thief, Where the thief will run away so your house is protected. So that you understand that something is wrong at your house, you can immediately call up your neighbor to look after your house.

Braille language learning kit for visually impaired people

There are large amount blind people in the world today and of them, many are unknown to specially developed language braille. Braille language is made up only 6 dots arranged in 3 rows and 2 columns. So there are total 64 combinations. In which 26 are used for alphabet and numbers.

We are making a mechanical plus embedded system which can represent Braille letters in some form. We can revolutionize the total process of learning braille.

The main motto of this Braille language learning kit system is to replace old fashioned “braille” books having tremendous weight.

Visually impaired people generally use heavy books having text on one side only. They use all their fingers to read. So to introduce them this language, the trainer takes continuous effort. We are planning to make pc software which can be used as personal trainer. Which contains some dedicated module for teaching braille.

Braille language learning kit Embedded system is developed using arm processor kit. Also, this system is the combination of electronics and mechanical system. So as to develop the mechanical system we are planning to use the combination of DC motors plus some platform.

Online Handwriting Recognition using Motion Sensor based Pen Device

With the advances in current technology, we see a rapid increase in availability, but also a demand for intuitive interaction between man and computer. While recognizing has been developed graphically based on the vision, it has some limitations, such as running a camera in one place, with the advantage of using motion sensors to develop a portable device.

Combining the rapid development of man-computer technology and the growth of portable devices, a handheld device integrated with motion sensors has been proposed to recognize handwriting by capturing interaction writing paths.

The goal of this Handwriting Recognition project is to develop a portable pen movement base for the online reorganization of letters or handwritten sensor numbers. Users can use this pen to write letters or numbers in the air.

Signs generated by hand movements are generated by in-device and transmitted to the PC for processing and additional signal recognition via a wireless motion sensor module. A handwriting recognition algorithm will be developed for recognition signals using measured by the sensor.

A portable device will be developed base pen with motion sensors (triassic accelerometer, compass and gyroscope), a microcontroller and a wireless transceiver. This pen-based motion sensor can be used to enter numbers or letters in a free space at normal speed.

The sensors are used to detect hand movements. The microcontroller collects the hand motion sensors and wireless transmitters signals in the main PC processor for processing and recognizing the additional signal via a wireless transceiver.

A Handwrite Algorithm (DTW) recognition is implemented to perform handwriting recognition using the signals detected by the integrated sensors in the device.

Bus Tracking System using GSM Module Project

Bus Tracking System:

Using  GSM Module and Microcontroller we are designing and implementing a time saving system for daily BUS commuters, which will give the information about the present position of BUS whenever subscribed by the subscriber for a particular BUS, which will have its unique code.

Scope of the Project:

  • Bus Tracking System can be implemented in government, company, college & private buses.
  • Can also be implemented using GPS system.
  • Ring can be developed for blind people to get the status of bus.

Brief Description:

In the Bus Tracking System project, an IR transmitter is placed in bus & IR RECEIVER unit is placed at bus stop. Whenever bus reaches bus stop our unit comes to know which bus has been arrived. The transmitter present in the bus transmits a certain code using RC5 protocol. Carrier frequency for RC5 protocol is 36 kHz.

IR receiver which is present on bus-stop detects the IR signals and gives the coded data to the microcontroller for decoding purpose.  Microcontroller is controlling block of the system. After decoding this code, which bus has arrived is decided.   The acknowledgement is given to the system user through SMS. This SMS is send whenever bus is arrived.  The subscriber numbers to whom the message has to be send is stored in the EEPROM, which is the memory element used over here.

The 89s52 microcontroller communicates with EEPROM using I2C protocol. Whenever a message is to send to the subscriber for the subscribed bus controller  fetches those subscribed numbers & then send the message through GSM module. Microcontroller and GSM module are interfaced through MAX 232. . MAX232 is a device which converts TTL voltage logic levels to RS232 & vice versa.

The GSM module sends SMS to the subscriber which is mentioned in EEPROM through AT commands.  AT commands are used to send SMS from GSM module. LCD is used to display which bus has arrived.

Android Based Bomb Diffusing Robotic Arm Project

Abstract:

The title of Project is Android Based Bomb Diffusing Robotic Arm and we can operate robot through android application. We are using metal detector circuit to demonstrate land mines ( heavy metallic objects beneath ground) .

The main reason why have you chosen this project is this project has easy to use android app and remote operation of robot and it can be useful in real time with sophisticated testing of the hardware for military operations.

Our Final year major Project comes under Embedded Systems domain as it combines both hardware and software.

Existing System:

Generally , bomb squad team goes on site and check for suspicious objects but it has risk of explosion if not handled situation with proper method. In our project since we are using robot, there is no life risk.

Design Explanation:

Design has four gear motors : two rear side with wheels and two front side with dummy motors. It has two more gear dc motors for horizontal and vertical track. Thus we can use gripper to hold objects and move it in vertical orientation i.e up or down. Colpit oscillator circuit is used to detect metal objects.

Tools:

We are using Arduino IDE and Embedded CPP code.

Design Results:

We are also using Proteus simulation software for showing design results .

Future Scope:

Android Based Bomb Diffusing Robotic Arm Project can be extended for unlimited range by using DTMF (Dual Tone Multiple Frequency) technology in which we can use mobile phone and control robot from anywhere in the world. High Detection range metal detector circuit can be used.
