Abstract
In recent years, many luxurious buildings have been built in South Korea. Luxury shops and services such as health clinics, fitness centres, beauty salons and banks – which place a high importance on their image – have moved onto the second, third, fourth and fifth floors of buildings. For the owners of these businesses, it is important to keep their windows clean – not to mention the shop itself. However, it is hard for them to clean their windows as often as they want, when their shops are located on the second floor of a building or higher. The aim of this study is to establish the performance criteria for an external window-cleaning robot that uses new renewable energy, and to develop a driving mechanism that meets such criteria. Through an interview with experts and research on the current state of related technology, the performance criteria for the robot were defined, and then the driving mechanism for its implementation was developed. The possibility of avoiding any obstacles without a stop was identified, but it is evaluated that there are limits to its applicability in that the system became more complex and more energy was consumed when implementing this functionality.
