Introduction to ECE Project Topic on PC Controlled Temperature And Obstacle Sensing Robot:
An obstacle avoidance and temperature sensing robot which is supervised by the computer is presented in this paper, this computer based temperature and collision control robot based on the radio frequency technology, implemented under the embedded system ultrasonic technology for its design, the main objective is to control the movements of the robot by not manual operation but using radio frequency technology we can achieve wireless control over the mechanical robots, this systems send commands to the robot through the micro controller, here we use a low power and high performance 8051 microcontroller with 8-bit processor, 32 data lines using different memory types such as UV-EPROM, Flash and NV-RAM these commands are derived from the control systems and based on the computer vision library we can attain obstacle detection through stereo vision, in this system sensors play a vital role in receiving the data, these are the perceptual system in the robot , the temperature sensors i.e.
Thermostats are the high sensitive temperature elements we use here, our project consists of the following major components, RF receiver and transmitter, RF decoder and encoder, ADC, motor drives for various power ranges, ultrasonic sensor, crystal oscillator.
The radio frequency technologies paved path for the wireless communications, these RF waves i.e. electromagnetic wave can propagate with the speed equal to light, finds enormous applications in radar, television broadcast divisions. Our project is mainly divided into two sections, Hardware implementation, and Firmware implementation.
In hard ware implementation we discuss about the design and assembly where as in firm ware implementation we come across the micro controller programming, software installations, the project design and implementation is explained with the help of a functional diagram. This sample circuit is implemented by interfacing with the computer and the experimental results are found to be satisfactory proving it is an reliable and effective device for controlling the mechanical movements of the robots with obstacle detection and with minimum collision.
