For a mobile robot to be able to work with people in their everyday environment it is essential to have the ability to localize itself using its internal representation of the environment. At the same time the robot needs to maintain this representation in response to the dynamics of the environment. This is very important because, for example, the appearance of a room in a house where a mobile robot would operate is not static over time: new objects are sometimes added, existing objects like pictures or carpets may be changed or moved, and old objects may be removed. This means that the map which the robot has built could become out-of-date after some time in a changing environment.
Our research focuses on how to update the robot’s internal representation of a changing environment during long-term operation. To this end, we introduce the following datasets which contain omni-directional images and/or laser scans along with odometry information recorded inside changing environments over a relatively long period of time.
