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. The sensors are the powerhouse of a robot’s feedback system and act
as eyes and ears. A wide range of sensors is used in a robot system to perform the tasks.
These include:
• Cameras allow a robot to construct a visual picture of its background.
• Microphones are used to detect sounds.
• Thermometers in some robots are used to sense temperature.
