i'm working on obstacle avoidance robot for my semester project & i need some help to complete my project and give it final touch.

The project is designed to build an obstacle avoidance robotic vehicle using ultrasonic sensors for its movement. A microcontroller of 8051 family is used to achieve the desired operation.

A robot is a machine that can perform task automatically or with guidance. Robotics is generally a combination of computational intelligence and physical machines (motors). Computational intelligence involves the programmed instructions.

The project proposes robotic vehicle that has an intelligence built in it such that it guides itself whenever an obstacle comes ahead of it. This robotic vehicle is built, using a microcontroller of 8051 family. An ultrasonic sensor is used to detect any obstacle ahead of it and sends a command to the microcontroller.

Depending on the input signal received, the microcontroller redirects the robot to move in an alternate direction by actuating the motors interfaced to it through a motor driver IC.

This concept in future can be extended in such a way that if a destination is fed to the robot, the robot can map the whole terrain and can reach its destination by deciding a suitable path and avoiding obstacles.

Applications:

1) This line following robot can also be modified to a walking robot in any surface by using only one motor with homemade fixtures as per the detailed instructions give.

2) Similarly the same walking robot can be attached with special magnetic material as per instructions to climb a wall of any vertical metallic surface say a refrigerator body.
