Title: Building a Basic Junior Solar Sprint Car


1
Building a Basic Junior Solar Sprint Car
  • Building a solar car can be intimidating the
    first time you attempt it. Watt Watchers of
    Texas has created this very basic car building
    power point to give you a starting point. Part
    of the Junior Solar Sprint program is to design
    the car. After you have figured out the basics
    of building a working car, expand on that
    knowledge by adding different wheels, creating
    different shapes, or testing different
    configurations of the parts. Good Luck.

2
Collect Materials
  • You will need
  • JSS solar panel
  • Wheel and motor assembly
  • Foam board and other construction materials
  • X-Acto knife or other cutting device
  • Glue gun
  • Velcro tabs
  • 2 Binder clips

3
Building the Car Frame
  • Cut out a base that is a 11cm x 33 cm rectangle
  • Write front and rear at either end of the
    rectangle on both the top and the bottom

4
Building the Car Frame
  • Draw a line 3.5 cm from either end of the base.
    This is where you will attach the axles. Draw
    this line on the top and the bottom of the frame.
  • Cut out a notch on either side of this line to
    allow space for the wheel attachments.

5
Building the Car Frame
  • At the rear end of the base, draw a line
    perpendicular to the axle line about 4cm in from
    the side. This line should go beyond the wheel
    attachment line.
  • Cut out this line so your hole is 1cm wide. This
    space will accommodate the gears.

6
Solar Panel Riser
  • Cut a piece of foam board 17 cm x 4 cm
  • Draw a line 4 cm in from each end
  • Score that line so you go through 2/3 of the
    material. You will be bending along the scored
    line

7
Solar Panel Riser
  • Bend at the scored lines to form a U shape.
  • Place the riser on the car in front of the notch
    you made for the gear with the arms of the U
    pointing toward the front of the car.
  • Glue this riser on the car frame.

8
Solar Panel Riser
  • Place the solar panel on top of the car and angle
    it down toward the front end of the car. Shave
    off the arms of the riser to reach your desired
    angle

9
Solar Panel Riser
  • Place a 2cm piece of fuzzy side (loop) Velcro
    on top of the riser and at the front of the car

10
Solar Panel Riser
  • Place the solar panel on top of the car again,
    making sure the metal leads are at the rear of
    the car. Mark the bottom of the panel where the
    Velcro should line up.
  • Attach pieces of scratchy Velcro (hook side) to
    the solar panel on your marks.

11
Front Wheels and Axles
  • Put the front wheel and axle kit together
  • Create or attach bearings
  • Ideas for bearings include
  • Cardstock bridge
  • Straw
  • A paper tube

12
Front Wheels and Axles
  • Attach wheel bearings to the line at the front of
    the car

13
Rear Wheels and Axles
  • Place the axle through the largest gear.
  • Attach bearings and the wheels to the axle.

14
Rear Wheels and Axles
  • Line up the gear with the notch you made in the
    frame
  • Attach the axle to the frame using the same
    method you used for the front wheels

15
Motor
  • Set the motor in the mounting bracket by placing
    the shaft through the large hole and securing
    with a screw.

16
Motor
  • Attach the largest gear (from the motor bag) to
    the shaft of the motor.
  • Place the motor next to the gear attached to the
    rear wheel assembly so the teeth line up.

17
Motor
  • Attach the motor to the car frame making sure the
    gear teeth are lined up.

18
Connections
  • Place your solar panel back on the car and
    connect the motor wires by placing the wires
    between the leads of the solar panel and applying
    a binder clip to maintain a secure connection.

19
Finished Basic Car
  • Your finished car should run forward and straight
    for the best results.
  • Now, expand on your knowledge and design a car
    with style and flair and a bit of solar ingenuity.
