Triangle Robot

Hi All,

In this instructable, I will share, how to make a simple robot at home with a dc geared motor. This project can be used to introduce simple robotics to kids

• DC geared motor
• 9V Battery and connector
• Cardboard
• Popsicle sticks
• Skewer or toothpicks
• Superglue
• Cutter
• Soldering iron

• We need 4 equilateral triangles with 8cm sides and a rectangle with 5cm x 8cm
• I have used box cardboard, which is thick
• Drill holes on the triangle at 1cm from each corner

• Cut 6 pieces popsicle sticks of 2.5cm in length each ( cut few extras, just in case )
• Drill a hole 0.5 cm from the edges
• Glue toothpicks on popsicle sticks, on one hole only
• Let this dry for few hours, donot rush

• Superglue two triangles and rectangle as shown
• Add support to avoid the triangles bending or moving away from the intended position

• Superglue two toothpicks on the motor
• Fix the motor in the body, such that the toothpicks can move easily
• Add toothpicks rails, all these should be easy to move, with minimum wobble and friction
• Add the popsicle arms as shown, all arms should make an equilateral triangle to match the holes on the triangle
• Glue the arms in place and leave it to dry
• Make sure you stick the rails and arms not the cardboard

• Add battery and test
• Give it to your kid to play

Note

• Make sure that the cardboard does not get stuck with the toothpicks rails or arms
• There may be friction between rails and carboard
• Replace battery based on motor
