Drawbots School Project, Competing Robots!

I've run a school robot build project a few times at local schools, where turn the classroom into an assembly line & test center for the day.
Students, with parental help, attach 3 marker legs, a vibration subassembly (that I kit ahead of time), & decorations to a tin can or plastic bottle.
When turned on, the robot buzzes & scoots along the floor, leaving colorful trails. The students test & adjust as needed, until it performs satisfactorily.
This video shows 2 Drawbots from the 2nd build, at transitional kindergarten. I got a little more efficient with my preparations the 2nd time around!

These drawbots are absolutely cute! 🥰
I would like to make one of these in my spare time for my brother's baby girl!
Awesome and creative design, Jason! No wonder you're an awesome inspiration for my project, Dragoma.
Take care. 😎

I'm working on adding details to my infernolab.com website regarding my Educational Outreach experience, & what goes into making some simple robots for youth projects. Thanks.
