Abstract—Rotary Automated bicycle Parking System (R.A.P.S) is a smart and flexible parking system aimed to make maximum utilization of the available space. The parking system currently available does not efficiently make use of the available space and does not have adequate automation features. To overcome this, a smart and flexible system needs to be designed. The vertical rotary mechanism is favored over the horizontal setup as it requires lesser space and can accommodate more number of bicycles in one unit. This project aims to design and develop a rotary automated bicycle parking system with the use of a rotary mechanism. The system can hold a maximum of 12 bicycles at a time. It consists of 4 docking stations, supporting frame, drive mechanisms, PIN code Reader and PLC. The work space of the system is 4m in width, 4.8m in height and 4m in length. The system is fabricated using Mild Steel which is treated and powder coated to avoid corrosion. Using Mild steel reduces the cost factor and improves the overall strength of the structure .The rotary docking stations are rotated about a fixed axis and are driven by a motor of 31 HP. Each docking station has the 3 inbuilt cycle stands. A PLC and a PIN code reader are used to collect Input from the user and process the same information into memory locations of the cycles. When the user inputs his/her PIN code the PLC detects the empty docking station in the system and allots that space to the user. Now the user places his bicycle in the docking station. The system locates the specific memory location when the user inputs the same PIN code again and rotates the system based on the memory location to the exit point.
