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.
This Arduino library provides a simple C++ class for ultrasonic distance sensors (SRF04, SRF05, HC-SR04). It supports measuring distances in centimeters or inches, object detection within a threshold, ...
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 ...
As robots increasingly enter human spaces, robotics companies will need to think about safety differently than they did when robots were largely siloed from their human counterparts. Sonair thinks its ...
Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (October 2025) that make the cut: ...
Abstract: Flexible proximity sensors mounted on robot arms boost obstacle detection in human-robot collaboration (HRC). However, most of the flexible sensor placements lack further analysis to exploit ...
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 ...
Metal Frameworks and Structural Elements in Robotics Every robot you’ve ever seen, whether it’s one zipping around ...
