Introduction

when we decided to make our graduated project,we thout in this way:

Since 1980, the robot has established itself in manufacturing. Now new demands for robots are spreading to other industrial fields like the construction, transportation, medical, military, and other fields.

The purpose of our project was to design a mobile robot that can overcome the terrain roughness, climb, stairs, run over trenches, … etc.


A crawler moving design was choosed for this purpose.


The movement of our robot is controlled by three D.C motors, the movement of camera is controlled by a stepper motor, and the overall system is controlled by the PIC microcontroller. RF link was used for the wireless communication between the robot and the PC. Depending on the command sent to the robot from PC, either the robot moves, or the camera moves. Image is transmitted back to the TV adapter card of a PC through the video sender unit of the wireless camera.

Our mobile robot equipped with camera mounted on top to transmit an image of environment in front of the robot.
 
This image will be received on a PC using wireless communication. An image is required to provide the required information about the environment to the operator controlling the robot movement.

Our Robot is called A Tele - Operated Robot.
