This paper presents a theoretical model with a system providing an assistive guided robot for a visually impaired person. The overall operation of this system works together with OBJECT DETECTION and LOCATION DETECTION. The robot consists of two parts - the HOUSING: is composed of five units: Main Unit (Arduino) , the Obstacle Detection And Avoidance Unit (Ultrasonic Sensors) and the Location Detection Unit (GPS , GSM , and micro SD card adapter ); and the HANDLE: is equipped with a Thumb-Controlled Joystick to control the robot and also provides significant force feedback to the hand of the user to help guide their path.
