Abstract
In recent years, various infectious diseases have spread worldwide, and handwashing is considered a crucial preventive measure. However, the method and timing of handwashing vary among individuals, and not everyone can wash their hands appropriately to prevent infectious diseases. Therefore, we developed an automated handwashing system to ensure that everyone washes their hands correctly. The system comprises four mechanisms: one for hand recognition, one for hand washing with a brush, one for dispensing hand soap and water, and one for drying hands. Upon hand insertion, the distance sensor recognizes it and the system starts operating. Hand soap is dispensed, and the camera captures an image to determine the hand size and the number of washes required. The system includes a brush that performs a set number of washes on the hands. The hands are then rinsed with water from the shower and dried with warm air. Once all hand washing operations are complete, the brushes are cleaned to maintain the cleanliness of the system.
