OBSTACLE AVOIDANCE ROBOT

ABSTRACT

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.
