Intelligent mapping and locomotion system for blind guidance robot

Robot movement in its working environment requires tracking the correct path between the start point and the end point. This paper employs artificial intelligence methodologies in mapping and path search procedures for robot navigation. Robot localization was determined using dead reckoning method with a new error correction algorithm. A topology and odometry unit along with a motion control unit is designed using a PIC microcontroller that controls the motors using PWM to drive the robot.
