Final Year Projects

The main purpose of the project is to control a robotic vehicle. This can be achieved by using RF technology for remote operation. It uses the 8051 series of a microcontroller to achieve its desired operation. This system uses push buttons at the transmitting end. With the help of these pushbuttons, the receiver is able to receive commands. These commands that are sent are used to control the movement of the robot which gives instructions for either to move the robot forward, backward, left or right, etc. The movement of the vehicle is done with the help of two motors that are interfaced to the microcontroller. The RF transmitter acts as an RF remote control. This RF remote control has the advantage of the adequate range that is up to 200 meters if provided with the proper antenna. The receiver is responsible for decoding and feeding it to some other microcontroller to drive DC motors via motor driver IC to perform the necessary work.
Further enhancement can be done by integrating DTMF technology with the help of which the robot can be controlled using a cell phone as it provides a long communication range as compared to the RF technology.

The project is designed to control a robotic vehicle using a standard TV remote. IR sensor is interfaced to the control unit on the robot for sensing the IR signals transmitted by the remote. This data is conveyed to the control unit which moves the robot as desired. An 8051 series microcontroller is used in this project as the control device.
Transmitting end uses a TV remote through which IR commands are transmitted. At the receiver end, these commands are used for controlling the robot in all directions such as forward, backward and left or right, etc. At the receiving end, the movement is achieved by two motors that are interfaced to the microcontroller. RC5 based coded data sent from the TV remote is received by an IR receiver interfaced to the microcontroller. The program on the microcontroller refers to the RC5 code to generate respective output based on the input data to operate the motors through a motor driver IC. The motors are interfaced to the control unit through the motor driver IC.
Further the project can be enhanced by DTMF technology. With this technology, we can control the robotic vehicle by a cell phone. This technology has an advantage over long communication range as compared to a line of sight communication in IR technology.

Today most of the industries use a robotic vehicle to carry out most of the task in order to automate processes and thereby save a lot of time and avoid many expenses. So in order to make the robotic vehicle free from a collision, here we propose a collision detector robotic vehicle that is not only capable to detect obstacles but also to avoid collisions. The vehicle uses an ultrasonic sensor with an arm controller to achieve this purpose. The ultrasonic sensor enables the robot to virtually see and recognize the object, avoid obstacles, measure distance. The vehicle can be controlled by the user using an android phone. The arm controller decodes users commands sent through an android phone. The system receives these commands through a Bluetooth modem and then processes this data. It then operates the robotic vehicle to achieve the desired movement. If an obstacle is encountered, the system stops the vehicle immediately. The system also makes use of a buzzer to alert the user about the obstacle. Thus now the industrial work can be carried out smoothly without worrying about the collisions with the help of robotic vehicles. This system can also be used in case of military applications or city wars.
