1.
Background
An
automated guided vehicle (AGV) is a type of robot that moves along a wire or
marker block on the floor through visual navigation or laser navigation, which
is mostly used in industrial production, in the workshop, warehouse
transportation [1]. It can programs a few paths and uses laser navigation to
make decisions about the path to advance. The advantages are saving manpower,
improving efficiency and reducing errors. At present, Shanghai Yangshan Port
Terminal has become the largest automated terminal in the world [2]. The figure
1 shows the automated guided vehicle; the figure 2 shows the Shanghai
Yangshangang port automated vehicle.

The
aim of automatic car parking system
Based on
the background, the group aims to apply the automated system to parking lot to save
manpower and improve parking efficiency. Therefore, the objective is to use
smart cars, cardboard and a variety of sensors to implement an automatic
parking system and apply it to the simulation of automatic parking in a real
large parking lot.

The
design of intelligent car parking system
In this
design, the entire system is divided into two parts, the parking lot has a
sensing system, and the car itself has a system. This intelligent parking
system will perform three functions. One is to sense the location of the car
when it enters the parking lot. The second is to perceive the number of
vehicles that have been parked in the parking lot. The third is to feedback the
actual road conditions and parking conditions of the parking lot to the car.
Therefore,
the simulated smart car will complete the following actions. First of all, it
can automatically execute the parking instruction based on the received parking
position information. The second is to re-route the route according to the
actual situation, for example, the obstacle appears in the original path, and
the car can execute the circumvention command.

Materials
and structures:
The
entire project is consisted of several programs and components which are shown
below.
Parking
board:
1)
Infrared sensor (To detect the
car or obstacle on the board)
2)
315hz wireless communication module
(To send the order from board to the car)
3)
Led screen (display the
essential information)
4)
Program (The main program of
this project which can plan the route and park the car without help)
Smart car:
1) Motor
2)
Velocity sensor (detect the rotating angle of the wheel and control the car)
3) 315hz
wireless receiver (To get the order from the board)
4)
Infrared sensor (the backup plan)
5)

The
plan for five weeks
Week 1:
Discussing
the final aim of this project and create a clear flow chart for entire system.
Week 2:
Testing
the components separately and making sure that all components can work as the
expectation. Then we will build the board and car to test the functions of
them.
Week 3:
In this
week, an initial model will be built for project (only a part of the parking
board and one car). We will try to make the project in a small board and adjust
the cooperation between the board and car to achieve the basic aim.
Week
4-5:
The
group will continue working on the function of the system and improve them to
achieve the final goal.
Week 6:
The
final test
