roomba docking station sensor


The roomba vacuum cleaner can sense the docking station and reach it following the shortest path.

Does somebody knows what kind of sensor is roomba using?

Here a video of the roomba reaching the docking station.

Thanks for your attention,

They use infrared emitters and detectors to find the way home but also to detect the virtual walls/lighthouses. The little knob in on the collision detector is the detector, the other devices have emitters that look almost identical.
