With the cities having modicum parking spaces compared to the escalating number of cars, this paper represents a meticulous design and development of a Compact Automated Parking System (CAPS), employing a vertical-rotary mechanism to maximize spatial efficiency. A functional prototype has been fabricated with seamless integration of Internet of Things (IoT) technology. This system enables users to remotely access the information of availability of parking spaces and park their car via secured smart cards, enhancing both comfort and security. The system presented in this paper is capable of storing 16-20 cars in the surface area typically required for just 2 cars. Engineered for resilience, the structure brings a lightweight sustainable solution. While the prototype in this paper uses Pulley-belt mechanism to lift cars, it can alternatively be accomplished with a Chain-sprocket system also. Furthermore, the utilization of the Blynk IoT platform ensures a user-friendly interface. Moreover, A highly calibrated control system facilitates smooth and precise operation. The performance of this system is evaluated through time and user based metrics and brought satisfactory results. The integration of automated vertical-rotary mechanism and IoT can be considered a novelty compared with existing systems. By and large, this innovative solution expects a paradigm shift in the domain of urban parking.
