A doodlebot is sometimes called a scribblebot or a wigglebot. It's a simple form of robot. There are all kinds of suggestions on YouTube and Pinterest on how to create one. The most important supplies are a battery and a small motor. The motor must be off-balance to create vibration. This will make the doodlebot move across the paper. We tried it with a battery pack and a DC toy motor, but it was too heavy. A cheap or old electric toothbrush does the trick really well. Here's a link for the instructions (you can see the picture above to see how we adapted ours):
A great book to read when inventing is "The Most Magnificent Thing" by Ashley Spires. We have it at the Ellison library, and we were lucky enough to talk to the author via Skype just this week! Why don't you try making a doodlebot or some other magnificent thing at home?
**This doodlebot is named Clara the Cow. She lives in Ms. Vicki's classroom and enjoys long naps on the bookshelf (when she isn't working).
Here are some three-legged scribblebots made by Grade 2 & 3 students with Mrs. Kurio in the library. They had a blast!
p.s. Toy, DC, or hobby motors can be ordered from Amazon. Locally, you may also find some at ABC Hobby on Dilworth & Harvey or at Wytek Electronics Parts on Dolphin.
To make a spinbot, all you need is:
Afterwards, kids can write words along the paths, if they like. A fun book to read together before or after the activity is "Happy Dreamer" by Peter H. Reynolds. You check it out from the school library. Have fun dreaming, creating, and spinning!
