Warning

Be careful if you are using a razor blade to cut tape. It is super sharp.

Info

You can use any strong double-sided tape instead of foam double-sided tape.

Foam tape is compliant. You can wipe it with alcohol and reuse it. It comes with a kit box.

Step 0: Parts lists

Parts used in this step

• 2 of servos
• Cardboard body

Attach double-sided tapes

• Attach two tapes at the left and right bottom corners.

Attach servos

• Tape the servo to the right and left corners of the body.
• Make sure blue servo edges are aligned with the body edges.
• Make sure that the servo shaft (white) is sticking out of the body.

After attaching both servos

Step 2: Installing ESP8266 and battery

Parts used in this step

• the Step 1 item
• ESP8266
• battery

Attach double-sided tape on the back of ESO8266

• Attach two tapes at the left and right bottom corners.

Attach ESP8266 to the body

• Tape the ESP8266 to the middle of the body.

Attaching the battery

• Tape the battery onto the ESP8266
• Make sure you don't block the servo pins (3-row headers)

Wiring the battery

• Connect the JST battery connector

Note

For attaching ESP8266 to the body, you may need to have a few layers of tape or use a piece of cardboard if you use non-foam tape.

The back of the servo shield is not flat.

Step 3: Connecting Servo

Wire left servo to D1

• Plug in the servo into D1 on the servo shield (the second from the bottom headers)
• Servo cable color codes-> Brown':' ground, Red':' Vin, Orange':' PWM.
• The brown wire should be outside (to the left)

Wire right servo to D2

• Plug in the servo into D2 on the servo shield (the third from the bottom headers)
• Servo cable color codes-> Brown':' ground, Red':' Vin, Orange':' PWM.
• The brown wire should be outside (to the left)

Step 4: Installing Tag

Parts used in this step

• the Step 3 item
• Aruco Tag (ID 1)

Tape the tag on the battery

• Tape the tag in the same orientation as pictured.
• The middle of the QR code will be the robot's origin. The arrow direction is x axis.

Step 5: Wheel Assembly

Parts used in this step

• the Step 4 item
• wheels
• servo horn

Attach double-sided tape on the wheel

• Attach tape at the center of the wheel.

Attach ESP8266 to the body

• Tape the servo horn
• Make sure the center hole aligns with the servo horn hole

Taking a screw

• Get a screw from the servo horn bag

Insert a screw into the wheel

• Insert the screw into the wheel hole.
• Make sure to insert from the cardboard side (not from the plastic horn side!)

Attach the wheel to the servo

• Insert the wheel into the servo.
• Screw in. You can use a plastic card or a razor blade if you don't have tools.

Repeat for the second wheel

Step 6: Attaching Head Support

Parts used in this step

• the Step 5 item
• head support

Fold the head support

• Fold the head support as pictured.

Attach the head support to the body

• Tape the head support to the body front


Test Drive!

Your kit comes with firmware pre-flashed. So now, let's get tested!

  1. Power on the robot (press the power button or connect the battery)
  2. Check if the ESP8266 blinks blue LEDs
  3. Open your phone's wifi setting
  4. Connect to ESP_xxxx (your ESP serial number)
  5. Go to your web browser, type in 192.168.4.1
  6. Now, you should see the "Yay Robots!" screen.
  7. Drive around!
