					About two hundred years ago, nobody could imagine mechanical devices running on
electricity walking and talking like human beings and doing all the work as good as
humans can do, if not better. The visionaries who dreamt of building such devices
were laughed at and their designs and suggestions were not taken into serious
consideration. Nobody could imagine that a day will come when satellites would be
manned by such devices; biped mechanical creatures would help doctors to operate on
patients; these devices would have Olympic games organized just for their
participations and they will spawn a whole new field of studies that will have the
world of scholars, scientists and the student community hooked to it.
 Welcome to the fascinating world of robotics, where impossible is nothing; where
you have robots designed to work in heavy industries in place of man performing all
the tedious and difficult duties with great results; where doctors rely on robots during
operations or treatments of patients; where spacecrafts are left in care of these bots etc.
From military technologies, to space explorations, from medical studies to commerce
or education, robots have made their mark everywhere and still continue to do so.
Robots can perform various tasks which human beings consider to be tedious and
difficult as well. There are robots which can deal with various harmful radioactive and
nuclear chemicals/devices. Robots have recently been used to explore inside human
blood vessels to detect any clot and subsequently remove it. Researches are going on
worldwide in renowned labs and universities to bring about revolutionary changes in
the field of robotics and small miracles are created almost on a daily basis. Such is the
great potential of robotics that many companies have come forward to build robots
commercially in association with labs. People have been buying bots for various
purposes, domestic, industrial or research. There have been robot fairs, exhibitions
too.

 What is a robot? It is defined as a mechanical device which is capable of interacting
with its ambience. It contains various sensors with which it can detect changes in the
environment which send this data as feedback helping it to act accordingly.
Microcontrollers form an integral part of robot construction. Designed solely for
embedded systems, these electronic devices are computers designed on single
integrated circuits with a memory, processor and programmable input and output
peripherals. These are preprogrammed and can interact with other hardware devices
which are the main controllers for robots needing intelligent automaton.
 The internet contains microcontroller tutorial which robotics hobbyists can
download to program their chips. Many websites are dedicated solely to explaining
8051 tutorial and also C for microcontrollers which are needed to program the device.
You need to learn Embedded C or C for microcontrollers as it is popularly called for
this purpose. Study the 8051 tutorial carefully, go through the datasheet to know the 8
pins and their purposes, the power requirement, the memory and other details. There
are excellent robotics websites with forums available in the internet where you can
ask questions and also share your views and get tips, suggestions etc.
 Apart from knowing about building the chassis, motors, power supply, sensors,
people must learn microcontroller programming to build a robot.
