GoBabyGo Car: Team Tygen

Remove all of the supplied parts from original box and assemble the car per the directions within the product manual.

Step 1: Circuit Check

Remove the seat screws and seat to check for the necessary electrical relay for the kill switch.

Step 2: Find "hot" Wire

Using a voltmeter, locate the "hot" wire coming from the pedal by testing both wires. The wire supplying 2.5-5 amps is the "hot wire" (in our case 3.02).

Step 3: Drill Hole for Kill Switch

We are placing the kill switch on the back, left, lower corner of the car for easy access. This allows a parent to flip the switch with their foot if the child is about to crash. After drilling the hole (1/2in. in our case), secure the switch into the hole and cover with the provided rubber sleeve to prevent from unintended snagging.

Step 4: Rerouting Electrical Current

Connect the "hot" wire found in Step 3 to either lead coming from the kill switch. Connect the other lead of the kill switch to big red. Then close the circuit by connecting the opposite lead of big red to the negative of the pedal (opposite of the "hot" wire). Wire tie the wires in place just below the connections to take any tension off of the connection and to secure the wire to prevent any potential snags below the car.

Step 5: Seat Belt Redesign

We cut slits in the seat to allow a path for a chest strap to be installed. The slit was cut on the edges of the seat to allow room for the child to grow. Then pass the Velcro chest strap through the slits and adjust the length according to the provided measurements of the child.

Step 6: Big Red Install

Remove the face of the steering wheel and remove any tabs that were set to align the face. Cut a thin piece of wood that covers the back side of the steering wheel and also has an ID less than the OD of big red. Attach the wood piece to the back of the steering wheel and mount big red on top.

Step 7: Wiring Rerouting and Organization

After mounting big red to the steering wheel turn the wheel to find the amount of wiring slack needed for the tightest turn. Drill travel holes for the wiring needed to connect the foot pedal leads, big red cables, and kill switch. Run the wires and return any wire routing plastic back into place.

Step 8: Steering Bar Design and Build

Drill holes in a PVC pipe to perfect match the holes drilled in the wood piece below big red. Cut the PVC to a length longer than the separation distance of the holes but less than the allowed width within the car. Mount the PVC pipe above Big red using bolts and a light weight spring. Proper spacers allows for the pipe to remain above big red until the spring is compressed to depress big red.

Step 9: Oxygen Tank Mounting

We designed 2 brackets to be used in the bed of the truck in efforts to secure the needed oxygen tank. These 3D printed brackets mount to the sides of the bed and create a cradle for the O2 tank to rest in. A mounted Velcro strap (similar to the one used for the chest strap is mounted on the floor of the bed and a gives an easy way to secure the O2 tank within its mounted cradle.

Step 10: Oxygen Tubing Guides

Using one piece of Velcro that has soft and looped material, cut into thin strips. The soft side will be mounted to the car and the loop side can be closed over the oxygen tubing, allowing for quick and easy removal at any time.

Step 11: Design Details

Add any design features to help the child feel as though the car is more personalized to him/her. We added Moana stickers, a WSU engineering hood sticker, and a laser engraved license plate.
