Track Specifications

Isometric View of Track showing both the day side (white plywood with black tape) and the night side (black plywood with white tape). Dowels are placed at the center of each arc and must not be knocked down by the robots:

Top View of Plywood with Dimensions in Inches
Note: The black sheet of plywood is shown in gray so that the centerlines are visible.

• All dimensions are in inches with the origin (0,0) located in the lower left corner of the plywood.

• All dimensions are measured from the origin.
• Dimensions to the centerline of the tape lines are shown.
• The radii of all arcs are 12.00 inches.
• The (X,Y) coordinates of the five arc centers are: (24.00, 24.00) , (72.00, 24.00) , (24.00, 72.00), (72.00,72.00), and (48.00,48.00). The center of the dowels will be placed at each of these locations.
• The joint between the two plywood sheets runs parallel to the X axis.
• The Finish Line is the 24” long piece of black tape located 30.00” to the right of the origin.
• The Start Line is the 24” long piece of black tape located 66.00” to the right of the origin.

Materials:

• Two 4’ X 8’ X ¾” sheets BC or better grade plywood.

• One quart of White Glidden Premium Flat Interior Paint (Home Depot # GLN9013-04).
• One quart of Glidden Premium Flat Interior Paint (Home Depot # GLN9013-04) tinted black.
• Five hardwood dowels with diameters of 0.75” and heights of 3.00”.
• One roll of ¾” wide black vinyl electrical tape.
• One roll of ¾” wide white vinyl electrical tape.
• 2”x4” boards and fasteners for constructing a substructure to maintain flatness of the plywood.

Construction Procedures

• Paint the best side of one sheet of plywood with one coat of flat white paint.

• Paint the best side of one sheet of plywood with one coat of flat black paint.
• Place the two sheets of plywood on a flat surface to form the 8’ X 8’ base for the track.
• Draw light construction lines as shown in figure 2 to locate the centers of the arcs and centerlines of the electrical tape.
• Draw dark ¾” diameter circles in the locations where dowels will be placed.
• Apply the 3/4'” wide black vinyl electrical tape so that the centerline of the tape is coincident with the appropriate centerlines on the white sheet of plywood.
• Apply the 3/4'” wide white vinyl electrical tape so that the centerline of the tape is coincident with the appropriate centerlines on the black sheet of plywood.
• To provide for maximum flatness, a 2”x4” substructure should be constructed and attached to the track.
