Technology integration has enabled value-added services and quality-of-life enhancement in almost all aspects of modern life. In this paper, we present a UAV and low-cost Bluetooth low energy (BLE) tags-based location search system which enables a cart take-home service for shoppers of a supermarket in a model smart colony. The presented system has quality-of-life enhancement as well as carbon footprint reduction effects and can be integrated with the existing security and/or transport system of the model smart colony. Conducted field trials on location accuracy of the system are also presented, showing that carts left by residents outside the home can be located within 6.58m and carts taken inside homes or buildings can be located within 16.43m.
