Following method for a car-like mobile robot using two IR sensors

In this paper, the embedded based fuzzy controller is implemented and applied for a car-like mobile robot (CLMR). We present the design and implementation of a fuzzy controller by using a microcontroller. The fuzzy controller utilizes a look-up table to realize fuzzy logic algorithm. The controller of the CLMR receives the information from the IR sensor via two analog-digital converters and a control servo motor via serial communication. These types of sensors and controller are simple and relatively low-cost devices. An illustrative example is given to show the experimental result for an accurate S-type wall-following and its robustness.
