For cleaning purposes I recently built this little robot. It uses a modified toothbrush to sweep floors. While doing so it whistles happy melodies in order to indicate how much it enjoys that work! With its infrared ‘eyes’, the robot detects obstacles and avoids them.
Getting never tired of cleaning
Since my household is now extraordinarily clean, I don’t need the little robot anymore. So I decided to release it in Brasília as you can see in the video above.
