MOBILE ROBOT WITH JOYSTICK

SECTION 1: PROJECT TYPE

Micro controller (AT89C51) hardware design with software development (Device Driver).

SECTION 2: PROJECT DESCRIPTION

           

            This project mainly designed to develop a robot used for moving the robot from source to destination with the help of the joystick (keypad).The joystick is directly connected to the robot. In this joystick we have controls for forward, reverse, right & left directions. In this we also provide the signal for buzzer also. In this we also designed the keys for some specific directions also.

SECTION 4: PROJECT OUTLINE

Ø  A brief introduction to internal architecture of micro controller.

Ø  An over view of programming of micro controller.

Ø  An overview on assembly language.

Ø  An overview on interfacing 16X2 LCD.

Ø  An overview of Buzzers.

Ø  An overview on interface of switches and led.

SECTION 5: INTERFACES USED

Ø  Switches interfacing.

Ø  DC motor interfacing

Ø  4x3 Hex keypad interfacing

Ø  Buzzer, switches, led interfacing with micro controller.

SECTION 6: SOFTWARES USED

Ø  A Cross compiler for compiling and linking the code written for AT89C51.

Ø  Serial communication software for downloading code to AT89C51.

Ø  Operating system: Windows XP.

REMOTE CONTROLLED PC BASED SPY ROBOT

  ABSTRACT

                 The main aim of the project is to capture images from dangerous areas and highly terrain areas where human access is not feasible. For this purpose we design a camera subsystem which captures the images and sends

 them to computer for further processing. The entire project is composed of 4 main sub-systems which are as follows:

·         Design of robotic rover

·         Mechanical design of robotic arm placed on rover

·         Interfacing RF (transceiver) circuit for transmitting the controls to arm.

·         Processing & rectifying the captured images in PC

             The control of robotic rover, camera is done by using RF. The camera is mounted on the robotic arm. The movements of rover and robotic arm are controlled with the help of a PC. Depending on the command transmitted through RF module to camera mounted on robotic arm, the camera moves and captured image is transmitted to serial port of PC. This captured image is processed in MATLAB using image-processing techniques for compression to make it easy for further transmission, as an ordinary image occupies a large memory on disk, now is the image is compressed and made available for transmission. The wheels are designed to move on any type of surface.
