Hello Everyone,

In this Instructables, I will share how to make a Triangle Robot, using a combination of recycled cardboard, skewers and 3d printed parts.

Design considerations

  • Environment friendly, use of recycled cardboard / wooden skewers
  • Reduce 3d printed parts and hence reduce iterations to improve model, avoid PLA wastage
  • Print only parts that I could not make
  • Reduce time to 3d print / build the robot

Step 1: What Do We Need?

  • DC Geared Motor with 2 sided arm
  • 3d Printed parts
  • Cardboard
  • Wooden Skewer (3mm diameter)
  • Super glue
  • 9v Volt battery
  • Wires and connectors
  • Paper cutter

Step 2: 3D Printing

Step 3: Body

  • The body is made from cardboard
  • Draw 4 - 8cm equilateral triangles
  • And a rectangle of 5.5cm x 8cm
  • Mark and drill hole about 1cm from each corner as shown
  • Superglue two triangles to the rectangle as shown

Step 4: Arms

  • Cut wooden skewers with 2cm as length
  • We need 6 for the arm
  • Superglue the skewer to the arms and leave it to dry for a couple of minutes

Step 5: Assembly

  • Superglue The arms to the motor joint/connector
  • Make sure each is glue at 90° and aligned to the rotating arm of the motor
  • Install the motor in Place
  • Add two skewer axles, make sure the arms and axle make a U and not a Z
  • Attach the two triangle legs
  • Cut excess skewer and super glue the caps

Step 6: Final Steps

  • Add additional cardboard to keep the motor in place, as shown
  • Connect 9V battery to the Motor, using ires and switch
  • Add some hot glue at the bottom of the body and the legs for friction
  • We are ready, switch one and play
