Design and Implementation of Mars Rover Using Wireless Technology
Aim: The main aim of this project is to develop a computer controlled mars rover with RF camera.
Project Description:
The main modules of this project is microcontroller, RF decoder, RF encoder, wireless camera, computer, motor, three wheeled vehicle etc. The RF data receiver is standard 433 MHz receiver and it can support 4 bit data type. The decoder chip used is 12D which has totally 12 address bits and 4 bit data, these 4 bit combinations is used to control the movement of car.
For Example
0001 - Forward
0010 - Reverse
0011 - Left
0100 - Right
In the computer side user can control the car by sending the commands to the microcontroller and the microcontroller will send these data into RF encoder & RF transmitter. Mean while the video signals send by the camera is captured by the PC using TV tuner card.
In the vehicle the RF receiver will receive the signals and decode it as commands using decoder chips, this decoded value is read by the microcontroller and will control the movement of car. Watching the video we can control the movements of the car.
