Design and Implementation of a Stick for Blind Humans Using Artificial Intelligence System and FPGA

Blind people need a means of assistance to help them carry out their daily activities without relying on the people close to them, so the researchers thought of using intelligence methods to make a smart stick that helps them bypass the obstacles they face while walking, the research examined the use of an image as a blind environment in a fuzzy logic system to find a path and avoid obstacles for blind stick. This demonstrates the effectiveness of the fuzzy logic algorithm for the smart stick and ensures the path by performing path behavior and obstacle avoidance to identify the best path for smart stick can access the target and avoidance obstacles. In this paper, one of the methods of artificial intelligence is presented, which is the fuzzy logic of making a smart stick, where an algorithm has been built in the Matlab program to avoid and bypass obstacles and cross safely and then upload a code in FPGA then connect with power supply, flat Vibrator motor, ultrasonic sensor, buzzer that alert when detect an obstacles. The result use of fuzzy logic gives the best results for overcoming obstacles because fuzzy logic depends on the principle of probabilities and the use of the FPGA chip is the best chip from the Arduino and the Raspberry because the FPGA works in parallel with several inputs and sensors. Thus, a smart stick has been designed with artificial intelligence techniques and a FPGA chip with great success.
