Abstract. In an autonomous mobile robot system the ability to control the robot
manually is needed. For that reason a mechatronics system and control algo-rithm on carrier robot are designed and realized using Fuzzy Logic Controller. The carrier robot system which is designed consists of the robot mechatronics unit and the control center unit. The commands which are sent from the control center unit via local network received by the embedded system. These com-mands are forwarded to the microcontroller and translated into carrier robot’s maneuver. An error correction algorithms using fuzzy logic controller is applied to regulate the actuator’s speed. This fuzzy logic controller algorithm is imple-mented on embedded system which has a limitation on computational resources. The fuzzy controller gets its input from a rotary encoder and a mag-netometer installed on the robot. The fuzzy logic controller algorithm using direction error protection has been able to detect and correct the direction error which the error value exceeds the predetermined threshold value (± 3 ° and ± 15 °). The carrier robot system has been able to run straight as far as 15 m with average deviation value of 22.2 cm. This fuzzy logic controller algorithm is able to give the response in the form of speed compensation value to maintain the direction of the carrier robot.
Keywords: fuzzy logic controller, fuzzy, embedded system, carrier robot, pulse
width modulation.

Introduction
In this paper the design of the control system is realized on a two-wheeled carrier robot. The robot has two wheels which have the functions as actuators and a passive wheel on the back of the robot. The robot uses two wheels control system so that the space needed for the robot maneuver is smaller. The fuzzy logic algorithm imple-mented in the robot controller is used to correct the directional error of the robot when the robot moving in a straight line.
