A new category of sensing technology transforms mobile robot vision from 2D to 3D, improves safety performance and provides 50-80% cost savings compared to traditional, LiDAR-based systems and sensor ...

This project uses an HC-SR04 ultrasonic sensor to measure how close an object is. A buzzer and LED react depending on the distance, similar to a car parking sensor. < 10 cm → buzzer and LED stay on.

Abstract: In this letter, we proposed an ultrasonic sensor-based resolution tunable displacement measurement system by using an extension spring. In the proposed method, a linear extension spring is ...

Abstract: Thanks to their ability to withstand many harsh environments and their low intrusivity, optical fiber sensors are now widely used. Fibers can measure various physical quantities, including ...
