Clearing litter is a vital job Ruben, we need inventions just like yours to help clean up our streets! A robot is useful because it eliminates the need for human helpers, robots can cover a lot more ground and get things cleared quicker, they also don't get as tired easily! It sounds like your robot would be really helpful in organising rubbish into trash cans where it should be, that way we can enjoy a cleaner and more attractive landscape. Thanks for your waste clearing efforts Ruben, keep inventing!
