This project implements a real-time closed-loop motor control system where motor speed is dynamically regulated based on obstacle distance. An ultrasonic sensor provides the reference input, an ...
This project demonstrates an Arduino-based Human Following Robot using IR sensors and an ultrasonic sensor. The robot detects a human presence in front of it and follows smoothly while correcting its ...
Abstract: Traffic congestion remains a widespread issue, often stemming from inefficient signal timing, weak enforcement, and poor traffic management. Traditional traffic lights follow fixed timers, ...
Abstract: In this paper, we propose the use of ultrasonic sensors for autonomous parking systems. In general, LiDAR sensors are evaluated to be advantageous in autonomous parking systems, but this ...
