How to make worm robot

In this project, we will learn how to make a worm robot using basic techniques. This project is great for a maker space or mechanical engineering challenge at school, library or home.

Once you learn the basics, you can experiment with different body styles and designs to make your robot faster. You can also set up a competition between friends to see who can build the fastest worm robot. Make STEM education fun!

Materials Needed

The good thing about this project is that you can get most of your “robot” parts from the trash. You can use recycle bottles, ice cream sticks and many trash items to create the body of your worm robot. Get creative!

For this project, you will also need the following materials:

Bottle caps
DC gear motor
Battery
Switch
cardboard
Battery connecter
Tongue depressors/ice cream sticks
Kabab sticks
Round sticks
Screw with bolt
wheel

Required tools:
Glue gun
Knife cutter
Pen cutter

Step 1: Robot Body

First you have to cut down the cardboard according to the given dimension as given below

Bend the cardboard to make this shape

Step 2: Cut the Rectangle
Make a rectangle of of 2.5 inch length, 0.5 inch of width

Cut the measured rectangle with the help pen cutter

Step 3: Drilling
Make the two wholes in a wheel both 1cm away from each other just like as shown in the given figure

Step 4: Shaft making

Take an ice cream stick and make two holes in it at 3-inch distance from each other as shown in figure given below and remove the extra part from it

Attach the motor, wheel and forward part of shaft with each other and pass the shaft from the rectangle hole

Now attach the backward part of shaft with the body of robot with the help of kabab stick

Step 5: Mount the Wheel:
Now it’s time to mount the wheels on the axle of the propeller car. If the cap is a little loose, you will need to add hot glue to the middle. Make sure the wheels are kept as straight as possible while the glue is hardening
