INTRODUCTION
The nature’s most spectacular creation is human brain. The main feature of the human brain is its ability to sense the obstacles and respond according to them. The men always want to transplant his ability to the artificial things so that they can not only sense the problem but also respond according to that.
In this competitive corporate world every organization wants to improve the efficiency as well as its productivity. To improve the efficiency of organization, automation is a preferred solution.
Robots help automate thousands of factories around the world, making the delivery of mail, packages and materials fast and efficient. Scientists and engineers have been experimenting with snow ploughs and even passenger cars that can follow magnetic lines in “smart” highways. These robotic vehicles can sense the road, obstacles and each other, eliminating traffic snarls and making our highways safer and easier to travel. Someday we’ll simply tell our cars where to take us and line following circuitry will help get us there safely and without effort.
Our project is RF based obstacle sensing robot, this project is microcontroller based we are using two microcontroller 89c2051 Atmel Controller and PIC Microchip’s controller , 89c2051 controller is used for sensing the RF signals and taking decisions according to that and PIC microcontroller is used for sensing the distance according to value given by distance sensor.

AIM OF THE PROJECT
Problem of moving a robot through unknown environment has attracted much attention over past two decades. Such problems have several difficulties and
complexities that are unobserved, besides the ambiguity of how this can be achieved since a robot may encounter obstacles of all forms that must be bypassed in an intelligent manner
Our aim is to design a robot that finds its way in a complex route. This Robot is going to be React on facing the obstacle It will move in other direction as the obstacle comes in its way robotic system capable to be navigated within its environment through logically acting on the sensed data to avoid such obstacles. The robot tries to locate
hindering obstacles, both stationary and moveable, plans ways to bypass these objects and, finally, acts according to the resulted plan.
