Özet

This study is about a mobile robot, a sub-genre of robots, especially used in the production sections of industrial areas to a high degree. In the study,  a mobile robot is designed for Electric Powered Wheelchairs to move by following the lines automatically in social areas if required, for the motion system to decide considering the obstacles that may appear in front of the vehicle and for helpers to control the system remotely. Unlike the works in the literature of robotic systems, Arduino Nano card has been used among dozens of varieties of Arduino card and thus the size of the circuit board is minimized. The body of the robot is printed out from a 3D printer. QTR-1RC infrared sensor couple has been used for the the system to detect white strip and MZ80 infrared sensor has been used to detect obstacles. Two iron wheels have been used in the front as the moving mechanism and two servos have been used in addition to a dual motor driver card for thrust and direction operations. Radio frequency model car control receiver has been added to make the power unit of the system active-passive remotely. In addition, hardware structure of the system has been completed by using side circuit elements such as connection cable, resistance, led and the Arduino card is programmed subsequently. While designing the software, cases such as led lights to inform the user according to data from sensors and sudden speed drops while making motor directions has been considered. In the tests performed after the implemetation of the system, no problem has been onserved in motion, but robot has been detected to go out of lines in curved roads sometimes. The system has reacted correctly in the tests performed to observe the situation when an obstacle appears in front of the robot, and the system has turned off the power to motors. It has been observed that, the power unit can be deactivated in case of emergency by controlling the system remotely, without cable. I has been observed that, the system can be used by modifying in accordance with the structure of electric powered wheelchairs.
