Go Baby Go is a national, community-based research, design, and outreach program that provides modified ride-on cars to children from birth to age 3 who experience limited mobility. My class of 2018-2019 inthe PLTW Pre-Engineering program took this assignment upon ourselves, and this is the step-by-step documentation of how we did the project.

Step 1: Material List

Step 2: Optional

Paint bare car base if desired (optional) with chosen colors.

Step 3: Optional

Paint the rest of the car by taking parts separately off and painting then returning them.

Step 4: Optional Music 1

Now install any newly decided parts you wanted to add. For us it is a music player and this is the code for the music player.

Step 5: Optional Music 2

Open up SFEMP3Shield file folder even when it is not seen as a valid library file.

Step 6: Optional Music 3

After entering the selected file, click on SFEMP3Shield.cpp to access all your needed files and check that they are all there.

Step 7: Optional Music 4

Proceed to click on the folder and go over to your coding sketch and upload them by clicking on manage libraries and finding the folder (remember only the SFEMP3Shield folder is required).

Step 8: Optional Music 5

After this the folder should be added to the coding sketch, and you should be good to go.

Step 9: Optional Music 6

Construct a wiring diagram for the music player to be added to your car.

Step 10: Optional Music 7

Create a start and skip button for the music player.

Step 11: Optional Music 9

Solder electrical wire and connect with the music player.

Step 12: Optional Music 9

Purchase and build a selector switch that will be used for the child using the car, to pull on a lever and hit a button to play songs when using it.

Step 13: Optional 9 Music

Obtain a leftover power cord from somewhere in your class and use it to power your newly created display.

Step 14: Optional -Underglow

While wiring up your LED headlights, if you wish, run extra electrical LED strips underneath the car on its bottom rims for an under-glow effect, hooking the ends however and wherever you wish.

Step 15: Optional-Underglow 2

Next, if you are adding the under glow, test out your LED strips while hooked up along the bottom of the car to see if they need fixing.

Step 16: Optional-Underglow Final

This is what the under glow should look like once completed.

Step 17: Building Car 1

Gather all car parts to be used.

Step 18: Building Car 2

Assemble the basic car base.

Step 19: Building Car 3

(Leave out the wheels for easier access to the car until the end.)

Step 20: Building Car 4

Make sure lights can handle available batteries and that lights are installed.

Step 21: Building Car 5

Decide placement of emergency items and possibly wanted add-ons.

Step 22: Building Car 6

Begin using desired shapes for car seats. On an easy to cut material, cut out diagrams for reference.

Step 23: Building Car Final

Construct wiring diagrams and plans however you like for lights or other things you want to change.

Step 24: Wiring- Connecting the Car System

Solder electrical battery terminal wire.

Step 25: Wiring- Connecting the Car System

Shrink wire sleeve for battery terminal wire.

Step 26: Wiring- Connecting the Car System

Cut into an early part of the breaking wire to wire in kill switch as a replacement. Use your soldered and shrunk wire for the new wiring.

Step 27: Wiring- Connecting the Car System

Wire your kill switch to your area of choice.

Step 28: Wiring- Connecting the Car System

Secure kill switch and wire it to the on and off button 3-D printed for car.

Step 29: Wiring- Connecting the Car System

Attach 3-D printed on and off button to the location of your choice.

Step 30: Wiring - Connecting the Car System

After this, make sure the car runs and that you wired everything to it correctly.

Step 31: Wiring- Connecting the Car System

Drill hole for electrical wires to be hooked through for lights.

Step 32: Wiring- Connecting the Car System

Construct electrical model for the plan to wire the lights.

Step 33: Wiring Connecting the Car System

Wire all your needed wires to the kill switch button once it is completed.

Step 34: Wiring-(Replacement) 1

Solder electrical wire for headlight installation if you wish to replace them.

Step 35: Wiring- (Replacement) 2

Next, wire up your new LED strips into the headlight and to the wire, soldering on more wire as necessary.

Step 36: Wiring Replacement 3

Continue and heat-shrink wire to go together as you finish the lights. Also note to make room for the music player and for the harness.

Step 37: Wiring-Connecting the Car System

Using your model diagram, finish hooking up your light electrical system.

Step 38: Reminder

At this point, you can begin to put the car parts back together as you finish areas of it. This allows you to work on parts that need the car to be more fully assembled.

Step 39: Harness Construction 1

Construct supports into which to drill the harness.

Step 40: Harness Construction 2

Hook and run the harness around the seat with the drilled supports and holes in the seat back to make it able to secure the child.

Step 41: Drafting-

Design ideas for a button for an off and off switch for the car.

Step 42: Drafting-

Make precise measurements for the button so that it will fit in the car.

Step 43: Drafting-

Enter the sketch into Inventor with accurate numbers.

Step 44: Drafting-

3-D print the design and finish the button. (Draft Buttons included.)

Step 45: Drafting

Unscrew button in order to make sure your springs are functional (draft button included).

Step 46: Drafting

Cut out an area to install the on and off drafted button.

Step 47: Drafting-

Apply part to the car.

Step 48: Seat Installation

First, cut material with foam cutter in the desired shape and measurements for a seat back.

Step 49: Seat Installation-2

Measure PVC pipe to use with your cut out shape for the back of the car seat (to reinforce it and give it structure).

Step 50: Seat Installation -3

Finally, install it inside the car (by drilling holes and connecting), making sure the seat back is firm with reinforcements and secure it to the car spot chosen for it.
