I look forward to teaching students about the Engineering Design Process through the building of BrushBots every year. Brushbots are robots students make using toothbrush heads, DC mini motors with leads, AA batteries, a battery pack with leads, and art materials of their choice. If you are looking for a way to engage your students while teaching the the EDP, this is the unit for you. Each student learns about EDP while going through all of the steps to build their own unique BrushBot. During the process students investigate the forces of motion that contribute to the way the BrushBot moves, and have to problem solve, collaborate, and engineer. Students learn how to make an electrical circuit to transfer the chemical energy inside of a battery into electricity, making their motor turn. They then realize that they have to off balance the motor to create strong enough vibrations for their BrushBots to move. I have taken a ton of time collecting pictures and creating a presentation (PPT presentation has been converted to a PDF so files cannot be edited.)that will take both you and your students through the experience of creating a BrushBot. I have included all of the tips I have learned over the years building these bots, links to where I order the motors and battery packs from, and lots of student examples. This is a STEAM unit your students will remember for years to come!
