1.Mission Statement
The mission of this design project is to build a scale model of a physical site to enable the user to simulatevehicular movement around the site.
2.Model
All dimensions and weights have a tolerance of ± 10% unless otherwise specified.
Figure 1 - Model Overview
Figure 2 – 3-D Model Overview
2.1.Overall Structure
The model shall occupy an area of 8’ by 4’ by 1.5’. The model will be divided into 4(four)2’ by 4’ partitions for ease of transportation. The model will be designed to be used indoors.
The entire model will weigh 140lbs ± 20%. Each partition will weigh 35lbs ± 20%.
2.2.Detailed Structure
The model shall be a generic landscape with various buildings and terrains.
Terrain
The terrain shall consist of mainly flat land covered with grass and turf. A rock/hill will also be included.
Scale
The model will be designed to a 1:43 scale.
Power
The model will require a 120V power supply connection.
2.3.Stationary Objects:
Model Base
The model base will be made with a combination of medium density fiberboard (MDF) and lumber studs.Each partition will have a surface made of a single MDF sheet and a support structure consisting of 2 (two) 2” by 4” by 2’ studs and 2 (two) 2” by 4” by 4’ studs.
Each partition will interlock with two adjacent partitions via groove/tongue stud connections and mechanical fasteners.
There will be three electrical connections between the partitions. The electrical connections will be made with power cables commonly used for computer hard disk and CD-Rom drives.
Buildings
The model will contain 5(five) buildings of varying colors and dimensions – One (1) 3-story building, three (2) 2-story buildings and one (1) single story building.
Building scale
1:43
Material
¼” thick polystyrene
Model Interface
Fastened to the model by detachable metal clips.
Roads
Roads will be represented by slot car tracks. Roadways will include an overpass, an underpass, left and right turns, and straight stretches.
Material
Slot car racetrack
Dimensions
302” long by 4.5” wide by 0.3” deep.
Model Interface
Tracks will be fitted into a groove engraved in the model base. Tracks will be removable from the groove.
Hill
There will be a single hill in between a section of the road and the border of the model.
Material
Molded grass mat.
Dimensions
8” diameter by 4” height
Model Interface
Glued to the model. Removable.
Vegetation
Trees and grass will be added to give the model a realistic look. A single forest will be represented by a cluster of trees.
Tree material
Artificial tree products.
Grass material
Vinyl grass mat
Model Interface
Grass mat will be affixed to the model base.
Trees will be removable.
2.4.Moving Objects
Vehicles
Vehicle with Indefinite Track
There will be a single mini-RC vehicle whose control is completely dependent on user input.
Quantity
1
Controller
Handheld remote controller with speed and direction controls.
Dimensions:

Vehicles with Fixed Track
2slot cars of different sizes that follow fixed tracks, whose velocities can be controlled by the controller.
Quantity
2
Controller
Built into model control panel. Forward and reverse speed control knobs for each vehicle. Includes one knob to supply power to the model.
