This paper introduces a novel method for arm flexion/extension angles measurement using wireless ultrasonic sensor network. The approach uses unscented Kalman filter and D-H kinematical chain model to ...

Many industrial processes involve particles in a carrier fluid, and it is often of interest to monitor the size of these particles noninvasively. The aim of this paper is to develop a theoretical ...

What if the tech you thought was obsolete still had a place in your life? The original Raspberry Pi, a tiny computer that debuted in 2012, may seem like a relic in 2025’s world of multi-core ...

Autonomous robot car powered by Raspberry Pi, using C and GPIO libraries to implement line following (PID control) and real-time obstacle avoidance with ultrasonic sensors. raspberry-pi real-time gpio ...

A new report says a plane equipped with advanced sensors for deployment to chemical disasters could have helped authorities avoid needlessly blowing open five rail tank cars and burning their ...

HC-SR04P or HC-SR04 Ultrasonic Sensor(s): Single Sensor Mode: 1 sensor. Multi-Sensor Mode: 1 to NUM_SENSORS (configurable, up to MAX_SENSORS defined in config.h). Note: The HC-SR04P variant is 3.3V ...
