Control follower robot speed based on ultrasonic echo

Abstract

In this research the dynamic speed profile generation system made up of fuzzy logic and ultrasonic sensors is evaluated. The echo power signal measurement permits us to endow the robot with capacity for pursuing and approaching to mobile target within short time and protect the robot and target of collision. Furthermore, given that the echo power-PWM controller provides a variable switching frequency, so high response will achieve for change target velocity and position. The proposed scheme is verified by simulation.
