2. Assembling your robot chassis

These are instructions for making a basic driving bot. If you've set your sights on winning the challenge, you'll likely need to customize your bot beyond this basic kit.

1. Assemble the chassis kit. Refer to the images below for guidance.

2. Push one end of a thick black wire through the top metal loop on one motor and bend the wire end into a hook to affix it to the loop. Hint: Solder will provide a more stable connection, but this will work for testing purposes. Hook a thick red wire into the bottom metal loop of the motor. Repeat these steps for the other motor.
3. Carefully feed the loose ends of the 4 wires through the holes in the chassis so that the emerge out of the platform. Affix the free ends of the motor wires to the screw terminals in the H-bridge (red-black-red-black). Hint: To affix a wire to a screw terminal, use a screwdriver to loosen the screw, push the wire into the door firmly, then tighten the screw well. See the photo below.

3. Gently plug the Feather board into the breadboard. Push firmly until it is seated all the way into the breadboard.
4. Attach six female-male jumper wires to the pins of the H-bridge as shown in the photo above. Connect the two pins labeled motor A to the Feather's pin 4 and pin 12. Connect the two pins labeled motor B to the Feather's pin 5 and pin 14. Connect H-bridge GND to the ground rail (-) of the breadboard. Connect H-bridge VCC to the power rail (+) of the breadboard.
5. Use a male-male jumper to connect the same breadboard ground rail (-) to the GND pin of the Feather.
6. Add 4 AA batteries to the battery holder. Plug the black wire into the ground rail. Then, plug the red wire into the power rail. Hint: You might want to leave the red wire unplugged until you're ready to drive the car in lieu of an on/off switch.
7. Optional: Add an on/off switch to your bot by following the circuit diagram below.
8. Plug in the USB power bank to the micro USB slot of the Feather board. If your battery pack's red wire is not plugged in, confirm that the black wire from the battery pack is plugged into the ground rail, then plug in the red wire from the battery pack into the power rail. You should see red and blue lights on on the Feather board and a red light on on the H-bridge.
9. Use a ziptie, rubber band, tape, or other mechanism to hold the breadboard, battery pack, and USB power bank to the chassis platform.

Your circuit should look like this. Note that H-bridges vary in design and screw terminal order and pin order might be different. Refer to the markings on your H-bridge rather than the specific pin order shown in the diagram. The right motor pins should go to pins 4 and 12; the left motor pins should go to pins 5 and 14.
