This paper introduces a pioneering approach to ultrasonic-based distance measurement using ultrasonic sensors. Recognizing the influence of diverse weather cond ...

This Arduino code utilizes an ultrasonic sensor to measure distances. When an object is detected within a fix distance , the connected motors trigger a sequence: move backward, turn right, turn left, ...

In this paper, we build a micro-ultrasonic motor in the 2–3 mm scale, combine it with a tunneling magneto resistance (TMR) sensor with dimensions of 1.4 mm ×1 mm, and construct a closed-loop system ...
