What is Sensor Based Robots?

Any real time system is not functional without the employment of sensor inputs almost all the electronic systems needs some inputs for desired outputs so there is a great need of different kind of sensor to sense different parameters present in and around environment such as infra red, light , sound ,heat, pressure, smoke, etc.

In sensor based robotics the sensors used are infra red, ultra sonic etc.., their function may vary for different applications. Some of the applications of these sensor can be used in line follower robots, obstacle avoider, obstacle follower, and many more.
