A coffee machine makes use of a valve arrangement for controlling the coupling of a water heater outlet selectively to one of two or more outlets, such as a steam delivery nozzle and a brew chamber. The valve arrangement comprises an active valve between the inlet channel and a first one of the outlets and a passive valve downstream of the active valve from the water heater outlet, coupled to a second one of the outlets. A cam surface controls the active valve, wherein the angular position of the cam surface controls the coupling of the inlet channel to the first one of the outlets. The rotation may be driven by rotational coupling to a brew chamber motor. This coffee machine design makes use of a single valve arrangement to provide the flow control from the water heater. This provides a compact arrangement with a low component count and simple control mechanism. It also enables all valve mechanisms to be outside the water or steam flow.

An autonomous mobile robot is configured to move across a floor area in accordance with a floor covering strategy and includes: based on a topological map of the floor area, designating a location of a current cell that is bounded by a primary boundary; executing a series of double strokes into and within the current cell, while mapping obstructive objects within the current cell onto an obstacle map; from the obstacle map, determining a secondary boundary of the current cell that encloses an area of the current cell covered by the executed double strokes, and distinguishes between secondary boundary portions thereof at which an obstructive object is located, and secondary boundary portions thereof at which no obstructive object is located; and adding the determined secondary boundary to the topological map of the floor area.
