- Two motor modules
- 9V module
- Slider module
- Card stock
- Plastic solo cups
- Conductive ink
- Hole punch
- Hot glue
- Knife or scissors
Step 1: Build a circuit for the robots body
The wheels of the robot will be attached to two motor modules on opposite sides of the card stock. The motors are connected to each other through the holes in the card stock.
Step 2: Making the robot
Now it’s time to make a body for your robot! The body needs to be big enough for the motors to fit inside, but small enough for the ends of the motors to be outside of the body. A good size for this circuit is 2” x 1.75” x 3” with cutouts for the ends of the motors to stick out. Glue the body together with the circuit in place and tape the battery to the back of the body.
Step 3: Constructing wheels
For the wheels, pull some plastic cups out of the recycling bin and give them new use! Have an adult cut the bottom of the plastic cup off. Add hot glue to the edges to give the wheels more traction. Cut a small hole in the center of the cup, push the exposed ends of the motor through, and hot glue it in place. Now your robot is ready to move!
Step 4: Add art to your STEM project.
Now it’s time to get creative and add details to your robot. We added a neck, head, and face. Plus we drew some details on the front.
Step 5: Watch your robot go!
Your robot is ready to move now. Turn it on and take your buddy for a walk!
