A new Robot vacuum cleaner can clean the house so we can have
more time for ourselves. The Robot was created by Rodney Brooks
at M.I.., in Boston Massachusetts. The robot is named Roomba.
When it moves through the house it avoids anything that is in front
of it. When it comes to stairs it turns away from them. The Robot
