One of the main goals of the study of robotics today is to understand not only the control systems used to stabilize the position, motion, and other forces of the robot, but also to allow robots to effectively work via sensors and actuators in dynamic environments.

The field of robotics has its origin in science fiction, the term ROBOT was derived from the English translation of a fantasy play written in Czecholosolvakia around 1920. It took another 40 years before the modern technology of industrial ROBOTS began. Today robots are highly automated mechanical manipulators controlled by computers.

First, let™s decide what a ˜robot™ is. To be a robot, it should have the ability to think “ make decisions. This may sound hard

IF FRONT LEFT WHISKER SENSOR IS ON THEN

STOP, GO BACKWARDS 2 FEET, TURN RIGHT, CONTINUE.

This is a very common ËœIF-THENâ„¢ statement.

A machine that can perform this instruction is truly a robot. So, the conclusion is that to be called a robot; you really need an on-board brain and a way to program it.

Classification of ROBOTS:
Robot like devices:
Prostheses
Exoskeletons
Telecherics
Locomotive mechanism
Classification by coordinate system:
Cylindrical coordinate robots
Spherical coordinate robots
Jointed arm robots
Cartesian coordinate robots
Classification by control method:
Non-servo controlled robots
Servo controlled robots
Point-to-point servo controlled robots
