Controller
Human beings and animals sense their surroundings through their sense organs and then react
accordingly based on the sense organs’ feedback. Robots use the same response system as human
beings—the feedback system. The CPU of a robot does the same thing based on data collected by
its sensors.
There are mainly two types of controllers that determine the robot’s behaviour. They are:
Simple Controller: Pre-Programmed robots use the simplest form of controller. These controllers
repeat the same operation over and over. Pre-Programmed robots are insensitive to their changing
environment. Car manufacturing robots are such kinds of robots.
Strong Sensory Controller: Autonomous robots are intelligent and change their response
according to their ever-changing environment. These robots have robust sensory tools that
allow detecting changes in the background. Humanoids, astronaut robots and robots used in the
educational and medical fields come under this category.
Sensors
Without the data supplied by the sense organs, the human brain cannot perform intelligently
in any given situation. Similarly, controllers would be unable to perform if the robot’s
sensors do not constantly feed the controller about their position, force, temperature, etc.
