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)
Example Wiring Diagram
Use insulated connectors or terminals for safe and easy maintenance.
