Abstract:

The complete contact-less sensory coverage of the workspace represents a fundamental difficulty for the navigation of autonomous mobile systems. Usually, several sensor systems are used in combination which could be complementary or redundant. The task of combining the information into a usable form, suitable for making navigation decisions, is known as sensor fusion. The use of the microcontroller in the robot system gives the opportunity to store a large amount of data gathered about the environment. The algorithms designed for obstacle avoidance during navigation are also easily executed. In this paper, a microcontroller system designed to control the navigation of a mobile robot while avoiding obstacles in its route is presented. A system of 24 ultrasonic sensors was designed and the operation algorithms were described.
