Additional Info

• What you will learn:

  • Science: The student learns about material recycling

  • Engineering: Mechanical engineering, programming

  • Technology: 3D-modelling and printing, basic electricity and electronics. 

• Expected Time:

  40h

• Materials & Recycled Materials:
  • Different size cardboard (3 boxes of around 30 x 30 cm)
  • Cardboard or plastic pipe (D=20-30mm)
  • Face mask string
  • Tape, hot glue, permanent marker and scissors
  • 6 servomotors nano-size
  • Arduino Servo Shield
  • 5V 1.5A power supply
  • 2 m electric wire 1 mm2
  • 1 m wire organizer cover
  • Additional for further step:
  • Arduino Uno 
  • Seeed Grove IR-movement sensor
  • Velleman 1W audio amplifier
  • 80hm speaker
  • 10kohm log potentiometer
• Guide:
  • 1. Plant the Arduino Uno inside the bigger cardboard box
  • 2. Cut two side holes in the cardboard box for arms and hot-glue two servomotors inside.
  • 3. Cut another hole for the robot head and hot-glue another servomotor for it inside.
  • 4. Choose two servoaxes to hot-glue arms cut from cardboard. Screw the arms to the servomotors once the glue is hard.
  • 5. Hot-glue the round servoaxis inside the neck pipe. Screw the neck to the head servomotor. Leave enough space in the neck pipe for the wires to go through.
  • 6. Cut servomotor holes in the headbox for the mouth and eyebrows. Hot-glue mask string to the headbox and servoaxis to form the mouth and eyebrows.
  • 7. Hot-glue a servomotor for head nodding to the neck pipe. Glue the headbox to the servoaxis.
  • 8. Connect the servomotors to Arduino’s corresponding connectors. Connect the servomotors and Arduino’s usage voltages together and wire all of them to the 5VDC power supply.
  • 9. Transfer the downloaded program to the Arduino and test the movements.
• Further Steps:
  • Try adding musical feature to the robot using the additional parts in brackets.
• Software used in the project:
  • - Solidworks
  • - Ultimaker Cura
  • - Eagle.
