One thought on “Solar Brainium”
It is a great idea to put rubber bands on the wheels. Do you think that makes a difference? The solar panel is flat. That is beneficial since the sun may be in different spots in the sky while you are doing your race. Is it adjustable at all or does it stay in one spot? Great job!
