WSU GBG Batmobile (Lonnie)

Introduction: WSU GBG Batmobile (Lonnie)

About: Students at Wichita State University run a program that modifies off-the-shelf ride-on toy cars for kids with disabilities. Our cars feature more technical builds with joysticks and arduinos. We post our instr…

Lonnie is much adored by his family. He has a genetic deletion and epilepsy. They are considering an ASD diagnosis as well. He is walking but seizes frequently, so the quality of his walking varies a great deal. This family loves Botanica and going to the park and Lonnie has started darting/running unpredictably. We modified a car in hopes to keep him engaged as he responded well to something similar at school. A big red button was attached to the steering wheel to allow Lonnie to start and stop the car easily. We added a foam pad to the door and seat for protection in the case that he seizes while he was in the car. We also added a cup holder because Lonnie likes to ride around refreshed. For our decorations, Lonnie said Batman was his favorite character. We decorated the entire vehicle with bat symbols, including bat signals that will shine through the headlights. We also included a batman mask and cape to complete the look. Finally, we added a kill switch in case Lonnie was feeling too heroic.

Step 1: Put the Car Together

Assemble the car according to the instruction provided.

Do not attach seat to allow easy access to wiring

Step 2: Big Red Button and Kill Switch

Throttle pedal was disconnected from the power supply, which was then spliced with the Big Mac Button

The car used a magnetic wedge to power the throttle so this wedge was soldered and stabilized to simplify the mechanism

The button was then connected to the power supply via the positive side of the circuit

The entire wedge mechanism was taped in under the hood to avoid moving or damaging it.

The positive wire between the power supply and rear wheel control was spliced with the kill switch.

This ensured that all power to the wheels was killed if the switch was flipped, but the vehicle remained on.

The wires were stripped, crimped, heated, and taped to ensure good connection and durable build

A hole was drilled in the back of the car and the kill switch was threaded through the back (a washer on the outside of the car helped keep the switch in place.)

Step 3: Attach Big Red Button, Handle Bar, Seat Belt, and Cup Holder

A wooden mount was cut out on the laser cutter to house the Big Red Button

A hole in the center of the wooden mount was cut for the wires

Holes were cut on the outside of the mount for the handle bar mechanism

The handle bar mechanism is then mounted on top of the big red button, using the springs and washers for suspension

The seat belt was screwed into each side of the plastic bench with two screws

The seat belt fabric was fed through the clips and a lip was sewn so that it the fabric doesn't pull through

All of the raw ends were burnt with a lighter to prevent fraying

The cup holder was mounted with 4 screws to the side panel

Step 4: Decorate :)

Apply vinyl

Apply LED lights under the car for extra style
