Abstract

Efficient storage and retrieval of electronic components remain challenging in laboratory-scale environments due to reliance on manual handling. This study presents the development and experimental evaluation of a laboratory-scale three-axis Automated Storage and Retrieval System (ASRS) prototype designed for electronic component management. The proposed system uses a combination of servo and stepper motors to provide controlled motion along the X, Y, and Z axes. It is managed by a Programmable Logic Controller (PLC) integrated with a Human–Machine Interface (HMI). Manual operation is used for system calibration and motion adjustment, while automatic operation facilitates sequential storage and retrieval processes. We evaluated the system's performance by measuring positional accuracy and deviation at multiple target rack locations. The results show that the system achieves positioning accuracy of 84.62% - 95.38%, with absolute deviations between 0.3 and 1 cm. These findings demonstrate that the ASRS prototype is a feasible solution for effective laboratory-scale automation in storage applications and for PLC-based educational purposes.

Abstract

The community service activity conducted with the partner GreenFarm Hydroponic aims to address the partner’s issue of conventional temperature regulation in the hydroponic system, where temperature levels fluctuate depending on environmental conditions. This instability reduces dissolved oxygen levels and inhibits plant growth. The activity includes training on the installation and operation of an automatic water-cooling system. The developed cooling system utilizes an Outseal Mega V2 Slim, NodeMCU ESP32, DS18B20 temperature sensor, evaporator chiller, outdoor AC unit, LCD, relay, contactor, and Blynk-based monitoring. This device is capable of maintaining water temperature at the ideal level of 27°C through both automatic and manual modes. The implementation of this technology not only enhances temperature stability and production quality but also facilitates remote monitoring and reduces manual intervention. This program demonstrates the role of vocational higher education in providing practical technological solutions that support the sustainability of hydroponic enterprises. The activity was successfully carried out, with GreenFarm Hidroponik now able to operate the automatic cooling system either via panel buttons or through the Blynk IoT application.
