Step 1. Prepare two LED lamps and a burner-shrink cable sleeve

These two lights will form the robot's eyes. Prepare a burn-shrink cable sleeve to add color. You will need a maximum of 13 cm of sleeve for this project.

Step 2. Cut out the sleeve

Cut two small pieces of sleeve, each about 1 cm long. This piece should be small enough that the LED leg will stick out once it is inserted into the sleeve.

Step 4. Shrink the sleeve with a soldering iron

Turn on the soldering iron and hold it close to the LED lamp and sleeve. The heat from the iron will shrink the sleeve. Hold the LED with pliers to protect fingers from heat.

Step 5. Select the battery case

Get a battery case that is about 3 volts. This case will hold two AA batteries.

Step 6. Strip the LEDs and resistors on the battery case

Take some insulating wires with the ends peeled off. Solder all these components in the following way:

  • Strip the negative (black) wire from the battery case to the short terminal of the LED light.
  • Take a 100 ohm resistor (or a resistor close to this value). Without a resistor, the lamp will turn off.
  • Patriot one leg of the resistor to the positive battery lead.
  • Patriot the other leg of the resistor to the positive terminal of the LED.
  • Connect the two positive legs of the two LEDs.

  • Connect the two negative legs of the two LEDs.

Step 9. Glue the motor to the battery holder with hot glue

Glue the motor over the battery holder with hot glue. Attach the battery mount cable to the motor leg.

Step 10. Finish the robot

Support the robot with the legs of the paperclip. Insert the battery and watch the little robot light up and move. Place it on a flat, soft surface so it doesn't roll over.

Tips

  • For safety reasons, wear safety glasses and use a fume extractor when brazing.
  • Add some sleeves on the legs to make them even more stylish.
  • Ask an adult for help if there are things you can't do on your own.
