Abstract: An innovative application of negative group delay (NGD) circuit embedded in a mobile platform for the real-time prediction of arbitrarily moving object position is developed in this article.

This program controls a robot using four servos and an ultrasonic sensor. It was developed for a competition using an Arduino Mega board. The ultrasonic sensor is used to detect obstacles and prevent ...

Tilt sensors are essential components in security alarm systems today. Standalone tilt sensors sense tilt angle or movement. Tilt sensors can be implemented using mercury and roller ball technology, ...

Before the digital age, when transistors were expensive, unreliable, and/or nonexistent, engineers had to use other tricks to do things that we take for granted nowadays. Motor positioning, for ...

Here is the schematic diagram of a Human-following robot circuit. This design incorporates three ultrasonic sensors, allowing distance measurements in three directions front, right, and left. These ...
