Leveraging Shifting Ultrasonic Sensors for Three-Dimensional Cargo Volume Determination

The logistics sector is overburdened trying to keep up with the demand for package shipments due to the impact of the growth of online sales on various platforms that make it easier for people to shop. However, there are still a few manual parts involves measuring and calculating the cargo volume. This research proposes a solution with a three-dimensional package measurement approach based on the Ultrasonics HC-SR04 sensor, Arduino, and DC motor to make volume calculation easy, cheap, and automatic. Volume measurement is equipped with a moving arm mechanism from 3 axes simultaneously. The system's ability was tested using a variety of package shape measurement scenarios. According to the measurement results, it can measure package dimensions and volume with an overall success rate of 82.66%, a flat box-shaped package success rate of 93.35%, a cylindrical shape success rate of 96.65%, and an irregular shape success rate of 33.33%. According to the test findings, it can be concluded that this method is highly effective to contribute to calculating the volume of regular-shaped package objects. This is because over 90% of the package shapes received are regular-shaped. However, measuring irregular shapes requires more enhancement to achieve accurate results.
