New vacuum cleaner robot, that is able to virtually clean the entire floor of a flat. It is completely made of scrap materials, mostly from broken vacuum cleaner parts. It is tracking items (chairs, tables, etc) and by turning around them it vacuums the edges. It also tracks walls to vacuum wall edges and corners as well. While its not tracking an item or wall, it draws spirals to cover the most of the surface of the floor.
In this video, you can see it cleaning around a couch by actively tracking it.
