Do you think you could build a robot on the head of a toothbrush? Bristlebots are simple, tiny robots that buzz around like bugs. They are easy to build and fun to play with, and you do not need any previous experience with robotics to make one. You can even build two bristlebots and race them against each other! Move on to the Materials section to see what parts you need to build bristlebots, and the
instructions for step-by-step directions on how to build them.
Use these free STEM lessons and activities to explore robotics with students. From designing and building simple robots to thinking about how robots can be used to solve real-world problems, these hands-on projects help students gain circuit-building and robotics engineering skills.
The free STEM lessons, projects, and activities below help introduce students to robotics, robotics engineering, and the kinds of algorithmic thinking used to program,…
Science Fair Project Idea
Have you ever wanted to build your very own robot from scratch? Bristlebots are a cheap, easy, and fun-to-build robot made from the head of a toothbrush, a battery, and a small motor. Once completed, they buzz along the top of a table like bugs. How can you make a bristlebot go faster? In this project, you will build bristlebots from two different types of toothbrushes, and race them against each other to find out.
