Do your kids think robots are cool? I know mine do. We started off with our wigglebot and wobblebot which both moved in fun ways while more or less staying in the same spot. Then I made a propeller car which moved in a straight line by pushing air with a propeller. The supplies for all of these projects are fairly inexpensive EXCEPT the propeller we used was around $4. Since I’m pretty cheap, I wanted to find a new method of getting a bot traveling without a propeller. This new “robot car” directly attaches the motor to the wheels with a rubberband, so it’s definitely cheaper to make. Also, the googly eyes are really what sell my kids on thinking this is a robot. :)
