HELPMATE is a mobile robot used in hospitals for transportation tasks. It has various on-board sen-
sors for autonomous navigation in the corridors. The main sensor for localization is a camera looking
to the ceiling. It can detect the lamps on the ceiling as references, or landmarks (http://

BR 700 industrial cleaning robot (left) and the RoboCleaner RC 3000 consumer robot developed and
sold by Alfred Kärcher GmbH & Co., Germany. The navigation system of BR 700 is based on a very
sophisticated sonar system and a gyro. The RoboCleaner RC 3000 covers badly soiled areas with a
special driving strategy until it is really clean. Optical sensors measure the degree of pollution of the
aspirated air (http://www.karcher.de). © Alfred Kärcher GmbH & Co.
