DIY STEM Project: How to Build a Motorized Bot

I love doing projects with the kids to help them learn hands-on. We received 2 motorized ArtBot kits from KitHub, and we had so much fun building them. Here is what we did for this DIY STEM project.
Each kit includes:
- Paper cup
- Hobby motor
- AA battery
- AA battery holder
- Coin cell battery
- Electrical tape
- 2 pipe cleaners
- 2 googly eyes
To build each bot, these are the steps we followed:
- Insert the AA battery into the AA battery holder.
- Attach the AA battery holder to the side of the cup with electrical tape.
- Fold a piece of tape around the motor shaft on top to make a flag.
- Test the motor. Attach the red alligator clip to the exposed metal of the (red) positive lead of the battery holder. Repeat for the black alligator clip and the (black) negative lead). If the motor spins, disconnect the wires.
- Tape the motor to the base of the cup so that the motor shaft does not touch the cup.
- Insert the wires of the LED through the cup to make a nose.
- Connect the coin cell battery to the LED wires and secure (we used a mini chip clip).
- Decorate your bot with pipe cleaner arms, googly eyes, and anything else you wish.
- Reconnect the wires and watch your bot wiggle and dance!
The look on my son’s face when the bot started moving was priceless. I wish I had 2 extra hands so I could’ve snapped a picture as soon as I connected the wires. I love seeing him connect the dots of how things work and how to create.
This project reminded me of my science projects when I was in school. It would be great for the classroom, homeschooling, or an educational after-school/weekend activity for home.
Have you done a STEM project at home? I’d love to hear about it!
