When Dustbot arrives you use a touch sensitive screen to open it. You can fill it with up to 40kg of rubbish.
The robot has everything built inside it. It has something called a gyroscope to help keep it upright, a GPS navigation system so it can find it's way around and sensors so it doesn't bump into people or get vandalised!
Dustbot is small and can get to places that rubbish trucks can't.
The fact that it comes to you at your convenience also means there aren't piles and piles of rubbish bags all over the streets!
Right now Dustbot is only in its early developmental stages - but interest from places like Japan means it could be patrolling streets in many parts of the world pretty soon.
