This is a fantastic invention Sofia! It's great that you have thought of a transparent umbrella so that the solar panels will work in all weathers, but still protect the Rainbow Rubbish Robot. The addition of tracks as the robots feet is very inventive, so they can get to any hard to reach rubbish. It's great that you are thinking of how rubbish effects our planet and thinking of ways to reduce it. Well done Sofia, looking forward to hearing of your next invention!
