The Nasdaq Foundation's Economic Opportunity Grant Program drives impact through five key areas—regional revitalization and rural wealth building, access to capital, employee and community ownership, ...

Abstract: Radar technology has been a cornerstone of numerous applications, from aviation to meteorology, offering invaluable capabilities for object detection and tracking. Traditional radar systems, ...

This project demonstrates an Arduino-based Human Following Robot using IR sensors and an ultrasonic sensor. The robot detects a human presence in front of it and follows smoothly while correcting its ...

This project implements a real-time closed-loop motor control system where motor speed is dynamically regulated based on obstacle distance. An ultrasonic sensor provides the reference input, an ...

Existing defect detection tools using ultrasound rely on phased array ultrasound. In this method, many transducers are pointed in the same direction to generate an image of that specific area. This ...
