| Summary: | Assistive Technology (AT) is designed to aid elderly individuals and those with disabilities in overcoming tasks that
may pose challenges or be inaccessible without support. Despite substantial research and innovation dedicated to the
advancement of AT, opportunities for further improvement persist in this domain. This study aims to enhance existing
technology by proposing an innovative, efficient, and environmentally friendly outdoor laundry garment hanging and
retrieval system. The proposed system employs the OMRON CPM1A PLC system as the central controller for the
motorized mechanism, offering a straightforward yet intelligent approach. The prototype harnesses solar power to
operate the automated clothesline system, contributing to energy and carbon emissions reduction, and promoting energy
efficiency and cost-effectiveness, hence improving sustainability. The prototype allows both manual and automatic
modes for controlling the DC motor's actions in extending or retracting the scissor-like cloth hanger. In manual mode,
a push-button switch governs the cloth hanger's movement, while automatic mode relies on input signals from rain and
temperature sensors to dictate its behavior. The DC motor will operate to extend the hanger (for drying) whenever the
rain sensor detects no water droplets, or, the light sensor detects more than 150 lux, or, the temperature is greater than
24.5℃. Otherwise, the motor will move to retract the hanger back into its original position when these criteria are the
opposites. This proposed solution not only reduces physical strain for elderly and disabled users during laundry drying
but also contributes to their enhanced well-being, accessibility, and improved quality of life. |
