ROBOTICS:

A robot is a virtual or mechanical artificial agent. In practice, it is usually an electro- mechanical system which, by its appearance or movements, conveys a sense that it has intent or agency of its own. The word robot can refer to both physical robots and virtual software agents, but the latter are usually referred to as bots. There is no consensus on which machines qualify as robots, but there is general agreement among experts and the public that robots tend to do some or all of the following: move around, operate a mechanical limb, sense and manipulate their environment, and exhibit intelligent behavior, especially behavior which mimics humans or other animals.

TRACK FOLLOWING ROBOT:

The line follower is a self operating robot that detects and follows a line that is drawn on the floor. The path consists of a black line on a white surface (or vice versa). The control system used must sense a line and maneuver the robot to stay on course, while constantly correcting the wrong moves using feedback mechanism, thus forming a simple yet effective closed loop System. The robot is designed to follow very tight curves. The robot initializes in seek mode, where it searches for a black line

to track. Wheel synchronization, during seek mode, allows the robot to travel in a straight line without guidance. Once a black line is found, the robot tracks the line

Practical applications of a line follower: Automated cars running on roads with embedded magnets; guidance system for industrial robots moving on shop floor etc.

Working Principle:

The aim of the line following robot is to search for a

black line on the terrain. Once the line is found, the robot

tracks the line from end to end. Four infrared sensors have

been mounted under the robot and connected to the port

of the AT89C51 do line sensing. The line follower is a

classic introductory robot design and requires a minimal

amount of resources. These line follower robots can use

microcontroller or simple digital or analog control

systems.
