- Rotary car parking systems utilize a mechanical system to minimize the space required for parking cars by rotating vehicles stored in cages or pallets either clockwise or counterclockwise. This allows parking of 6-40 vehicles in the space typically used for only 2 vehicles. - The system described uses an Arduino Mega microcontroller, keypad, LCD display, motors, motor drivers, and other components to control the rotation and retrieval of vehicles from the parking structure. User inputs the space number using the keypad and the system parks or retrieves the vehicle accordingly. - Rotary parking systems provide advantages over traditional parking by minimizing land usage, reducing parking damage, and eliminating time spent searching for vehicles or spaces.

3. INTRODUCTION
О An automated (car) parking system (APS) is a mechanical system designed to minimize the area and/or
volume required for parking cars. Like a multi-storey parking garage, an APS provides parking for cars on
multiple levels stacked vertically to maximize the number of parking spaces while minimizing land usage.
О 1st Multi-level Automated Car Park was built In 1905 in Paris, France at the Garage Rue de Ponthieu.
О With Elevator.
О Most Famous car park in History of this type is in Europe named as ‘Car Tower’.
О Currently Largest Automated Car park in the World is in AL Jahra Court Complex in Kuwait having 2314
Car Spaces At a time & Mumbai also have Largest ACP in India with 1100 Car Spaces Made by ‘WOHR
Multiparker 760’.
О In the early 1990s, nearly 40,000 parking spaces were being built annually using APS in Japan. In 2012,
there are an estimated 1.6 million APS parking spaces in Japan.
О Type of Automated Car Parking System
О Robotic parking garage.
О Rotary Parking System
О Automated parking facility (APF)
О Automated vehicle storage and retrieval system (AVSRS)
О Mechanical parking.

4. О Rotary Car Parking System is similar to a giant wheel mechanism, Where vehicle is put in the cage or
pallet, the same can rotate either clockwise or counter clockwise (bidirectionally) in rotary movements.
This design enables you to park either 6,8,10, or 12 upto 40-50 vehicles in the space of only
2 parking spots.
О A rotary parking system (RPS) is a mechanical system designed to minimize the area that is required for
parking cars. On the other hand, Rotary parking is known as “robotic parking garages”, however, this
technology is not used a lot in traffic engineering everywhere. Nowadays, with the huge increase in
number of cars it becomes difficult to find a parking place; therefore, many countries such as Germany
and Japan tend to build rotary parking systems in the areas near to the buildings and markets. The
concept for automated parking system is driven by two factors:
О A need for parking spaces and
О A scarcity of available land.
О However, the RPS utilizes a mechanical system to transport cars to/from parking spaces (rather than the
driver) in order to eliminate much of the space lost in a multi-stage parking garage. While a multi-stage
parking garage is similar to multiple parking lots stacked vertically. An RPS is more similar to an
automated storage and retrieval system for cars.
О China has current largest Rotary Parking System in GAOTANG COUNTY, Shandong with 280 Spaces
having 24 unit of 12 car capacity each. Placed within 0.2 Acre which near saves 1.7 Acre space. Which will
be used if that 280 cars parked Traditional side by side.
О India’s 1st made in India Rotary Parking System is at Mumbai build by Kamala Builders & Developers having
capacity of 6-20 cars.

5. Why It’s Necessary
To use Such Systems
• Use of Minimum Land Space for Parking purpose
• To Eliminate much of the space used in a Traditional Parking.
• To Eliminate Minor parking lot damage such as scrapes and dents.
• To Eliminate time used in Walking/Driving around for searching of the
parked car/parking space.
• To ensure car security during parked in Parking lot.

The Arduino Mega 2560 is a microcontroller board based on the ATmega2560
as shown in Figure. It has 54 digital input/output pins of which 15 can be used
as PWM outputs, 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz
crystal oscillator, a USB connection, a power jack, an ICSP header, and a
reset button as show in Table. It contains everything needed to support the
microcontroller; simply connect it to a computer with a USB cable or power it
with an AC-to-DC adapter or battery to get started.

11. Working principle of circuit:
The control circuit contains keypad that user will press the room’s
number through it, if the code is right the room will be ready for
parking, user park the car and exit parking area, then the gate
will be closed when he presses ‘HOME’ push button or after 2
minutes delay. In returning car case the system will operate in
the same principle.
Connection Circuit:
Computer simulations have become a useful part of mathematical modelling of many natural systems to observe their behaviour.
It allows the engineer to test the design before it is built in the real situation; the simulations for this system were performed
in PROTEUS program shown in Figure. These software applications are widely used in control engineering for both simulation
and design. And as shown in Figure explicated system Inputs and Outputs.
System Flowchart:
A flowchart is a type of diagram that represents an algorithm,
workflow or process, showing the steps as boxes of various kinds,
and their order by connecting them with arrows. This
diagrammatic representation illustrates a solution model to a
given problem. Flowcharts are used in analyzing, designing,
documenting or managing a process or program in various fields.
The flowchart illustrates the principle of system.

12. • Space required for two cars in RPS Max. 6.5M×5.2M
• China's Gaotang County, Shandong has 280 car spaces
Means Approx. 8085m2 (2 Ac) land required if we park that
280 cars traditionally side by side.
But due to RCPS this system placed within only 800m2 (0.2Ac)
Land. Thus 1.7Ac land was saved.
• Cost of RPS : As per Manufacturers Catalogs
(https://www.indiamart.com/)
Approx. 2 Lakh to 4.75 Lakh for unit of 6 cars and capacity
upto 2.5-3 ton each pallet.
Approx. 5Lakh - 7.50 Lakh for unit of 10 cars
Also it will varies from Manufacturer to manufacturer & part,
capacity and automation used in system.

13. Designing and manufacturing of a rotary parking system is one of the responsibilities towards our country as
these types of parking will help to solve the traffic jam issue in Palestine.
This prototype including the mechanical structure will moved using suitable electrical actuates which will be drive
and controlled by microcontroller system "Arduino Mega"
Finally, several points have been concluded throughout the preparation of this repot, such as:
1. Choosing a suitable microcontroller type that fit the requirements of our application.
2. Building the appropriate connection of the electrical circuit.
3. Controlling and driving the project actuators
4. Develop a full solid works drawing for mechanical structure
CONCLUSION
Future Scope
The RPS can be installed with a safety installation such as, whenever there is human movement in the system, the rotation of the
system should be immediately stopped. The platforms can also be equipped with safety sensors guiding the movement of vehicles in
the platforms. Moreover, the model can be programmed in such a way that the trolleys traverse the minimum possible distance during
parking as well as the retrieval of the vehicle.
It can be fully automated by integrating it with a panel board, such that whenever a particular number is called on the panel board, the
respective platform should appear at the ground level. This calling can also be made more secured by providing each platform a
specific password, so that only whenever a particular password is typed the platform is retrieved. A turn table can be incorporated
with the system in front of the ramp of platform so that cars can be easily turned and parked into the platform. This is very useful in
the areas where cars cannot turn easily to get into the platform.
