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

Step 1: What Do We Need ?

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

Step 2: Prepare : Cardboard

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

Step 3: Prepare : Popsicle Sticks

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

Step 4: Body

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

Step 5: Assembly

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

Step 6: Testing

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
