An embedded system is a large or small computer system that is built into a product, a piece of equipment or another computer system, and that performs some task useful to the product, equipment or system. It is a computer system that is programmed to perform a particular task
All embedded systems have these features:
they perform a very well-defined task for the product, equipment or system in which they are found
They do not permit user interaction with their operation except where such interaction may be the task of the embedded system, and
they are considered to be a component of the (usually much larger) product, equipment or system.
Various fields of Embedded systems include
Biomedical
Heart Beat Monitoring systems
ECG and EEG Monitoring
Pulse oxy meters
Anesthesia controller
Blood Glucose meters, etc.,
Robotics
Fire Fighting Robots
Autonomous Robots
Material Handling Robots
Two Axis and Multiaxis robots
