Abstract: The article dives deep into the complications and inspects the development of a real-time obstacle detection system designed for UAVs and drones with the integration of advanced computer ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

This project measures the height of static objects using ultrasonic echo-ranging. The sensor is mounted at a fixed height (30 cm), and the object's height is calculated by subtracting the measured ...

Abstract: This paper presents the simulation and experimental investigation on mapping done using ultrasonic sensor(HC-SR04). Issues related to exploration, mapping and localization are discussed.
