GoBabyGo Instructions

This page will include information on modifying a battery-powered car to be used as a mobility device.

Project Overview

GoBabyGo is a nationwide program that modifies battery-powered ride-on cars to provide mobility for children with disabilities. As a high school robotics team, this project lets you apply engineering skills to a real-world cause while giving back to your community.

Materials Needed

Ride-On Car Base

• Fisher-Price Power Wheels or similar 6V or 12V ride-on toy

• Must be large enough for the child to sit upright comfortably

Electrical Components

• Large push-button switch (easily activated by hand, foot, or head)

• 12V battery (if upgrading or replacing)

• Inline fuse (15A–30A depending on motor)

• Toggle switch (optional, for caregiver shutoff)

Tools

• Screwdrivers

• Wire cutters/strippers

• Drill

• Soldering iron and solder (optional)

• Zip ties, Velcro straps, heat shrink tubing

Adaptation Materials

• PVC pipe (for supports or harness frame)

• Pool noodles (for padding and safety)

• Foam for seating support

• Velcro and fabric straps

• Hot glue, duct tape, zip ties

Build Steps

1. Choose a Car and Assess

• Select a suitable ride-on car based on child size and needs

• Test existing wiring and motor function

2. Disassemble for Access

• Open the car body to access wiring and battery

• Remove or disable original foot pedal

3. Install Activation Switch

• Replace the foot pedal wiring with a large, easily accessible push button

• Use a Normally Open (NO) switch

• Mount the button in a location accessible to the child

• Add an inline fuse for safety

4. Add a Parent-Controlled Power Switch

• Wire a toggle switch in series as an on/off control for caregivers

• Optional: Use a wireless remote shutoff if available

5. Build Seating and Support

• Use foam, straps, and padding to ensure upright and safe seating

• Use Velcro or screws for removable and adjustable support structures

• Do not glue or drill into the battery compartment or structural parts

6. Add Safety Features

• Cover all hard surfaces and corners with padding

• Ensure speed is limited (typically <2 mph)

• Consider adding a soft harness or seatbelt if needed

7. Test and Iterate

• Test the vehicle without the child first

• Verify motor performance and button reliability

• Conduct a test ride with caregivers present

• Adjust as needed

Safety and Legal Considerations

• Always work under adult supervision

• Consult with physical/occupational therapists if possible

• Get signed parental/guardian consent before modifications

• Label all modified parts

• Document everything

Extra Features (Optional)

• LED lights

• Sound buttons (horns/music)

• Remote control override

• Adjustable or modular seating for future use

Working With Families and Therapists

• Listen closely to caregiver and therapist feedback

• Customize button placement and seat support as needed

• Offer post-delivery adjustments

• Communicate regularly

Documentation

• Take photos before, during, and after the build

• Maintain a modification log

• Create a printed user manual for the family

  • Charging instructions

  • Button use

  • Safety tips

Delivery Day

• Present the car in an accessible, open space

• Involve the whole team for a celebratory moment

• Provide final instructions to caregivers

• Take pictures and share (with permission)
