This project involves modifying a children's car to allow them to use their possible abilities. The cars will be designed with safety in mind and will include other modifications based on their needs.
Create a plan on how to make the modifications needed for the car and gather materials needed for the modifications.
Add the modifications to the car and test the car.
Ready the car for the client.
Step 1: Getting Tools and Materials
Hot glue gun
Drill with drill bits
Number 2 and 1 Philips head screwdrivers
Mercedes Benz coupe
Back up camera with extra camera
Nuts and Bolts
Heat shrink connectors
16-gauge wires: red and black
PVC 10ft schedule 40
PVC T x2
PVC 45 x 2
PVC 90 x 2
PVC cap x 4
Drywall screw 8 1/2" x 8
Vex standoff x 4
Hitec mega giant 2BB servo
Arduino Uno R3
Sun founder joystick PS2 module for Arduino and Raspberry Pi
Active buzzer module
10 pcs male header pin
Sparkfun MP3 player shield
120 pcs multi-colored DuPont wire 40 pin male to female
6V Voltage regulator
2 channel 5V relay module
Ice cube Relay 12VDC
100 pcs 5mm pitch PCB mount screw
DC 5V ultrasonic distance sensor x 2
Step 2: Making 5-Point Harness
The 5-point harness was mounted on the PVC structure that was attached to the 3-D printed mount.
We used rivets and grommets to hold the 5-point harness on the bar. The other 3 points were screwed into the car.
Step 3: Wiring
The diagram shows how the car was wired into the Arduino. The battery was wired to the kill switch, and then it was wired to the Arduino. All the electronics were wired to the Arduino. The servo was mounted on the axle of the vehicle and strapped by Vex c channels. We relocated the charging port to the right side of the vehicle. Then the joystick was wired in and was shrink wrapped. Wire management was the last thing we did.
Step 4: Code
1. Download Arduino IDE
Plug the Arduino into the computer with Arduino IDE installed via USB.
3. Copy the code from the GitHub link and correct any formatting errors.
4. Test the board to ensure it is giving the correct outputs based on the wiring diagram found in the "Installing the Arduino" section.
5. Check that all components are functioning properly before installing.
Step 5: Camera and Sensors
Cameras were mounted on the front and the back of the car's bumper. Sensors were mounted underneath the camera for distance sensing. The LCD screen is mounted on the table so that Greyson can see what's going on behind him. If he does get too close to something the sensors will go off and then halt backing up.
Step 6: 30 Degree Seat and Table
Lumber was placed underneath the seat to prop up the seats at a 30-degree angle. The table made of plywood was placed on the place where the dashboard was. Wires were pulled from the side of the table for the camera and joystick.
Step 7: Summary
Remove all components in the car. Cut then installed in a table to the necessary size. Mount the computers in the hood. Mount the chair at 30 degrees and use lumbar to close open space. Cut a foam board for the back of the seat. Wire the components and do wire management. Then present your car after cleaning and vacuuming your car.
Step 8: Finish Car
You are now done!
