A pocket-size ultrasonic bladder-volume sensor has been constructed and tested with successful results. This paper describes the sensor and presents results from its use on healthy volunteers.

We introduce a soft robot actuator composed of a pre-stressed elastomer film embedded with shape memory alloy (SMA) and a liquid metal (LM) curvature sensor. SMA-based actuators are commonly used as ...

Water level monitor using open-source microcontrollers (Arduino, ESP8266, ESP32) and ultrasonic sensors HC-SR04 / JSN-SR04T and similar with Trigger and Echo signals. Arduino Core & ESP-IDF ...

A real-time object detection and distance measurement system using the HC-SR04 ultrasonic sensor, developed in Embedded C for the LPC1768 microcontroller using Keil μVision.

Abstract: This paper presents a multi-ultrasonic-sensor system designed for Simultaneous Localization and Mapping (SLAM) on the open source robot Kobuki Turtlebot. The operating system used in this ...

Ultrasonic time-of-flight (ToF) sensors come to rescue indoor sensors, which often fail to detect and avoid barriers like plexiglass walls, translucent doors, and glass windows. Here is how ToF ...

It claimed this would be the industry’s first 3D ultrasonic sensor operating in air receiving such certification. Sonair’s acoustic detection and ranging technology equips AMRs with omnidirectional ...
